- Is your PC not booting? Try these helpful tips and lean the methods I use when troubleshooting PCs.
- Just to add something here; I also recommend purchasing a small PC speaker that plugs directly into your motherboard if yours doesn't sport Dr. Debug or troubleshooting LEDs. The beeps codes can come in very handy in the event your computer refuses to POST.

before you start to troubleshoot your pc you will want to get a drink.
whisky, vodka, rum, gin, whatever, you will need a drink.
100% agree
I've found I've had better success troubleshooting pc issues with red wine than beer or hard liquor.
I tried to troubleshoot my PC when drunk once.
The pins fell out of a molex connector, i put them back but got the 5V and 12V lines crossed...
Impressively loud bang that shot the CD drive tray open and literally exploded the CDROM controller chip on the drive. (luckily no damage to the rest of the PC)
Ever since i don't recommend PC troubleshooting + alcohol ;)
A good beer works best.
Thats where im at right now😥
Have you tried turning it off and back on again?
Also unplug the power cord, leave it unplugged for a minute or two, then plug it back in and try again. I've found that worked when the PC has been dead after a power outage.
It's always worth trying the simple, easy to do, things first.

Hahaah none of them got the joke
no, mom, i haven’t
IT Crowd, anyone?
Did you... Step on it?
or... drop it?
oops wrong channel
lol, that was linus break tips
he did step on 1 of his x99 motherboard n the pin bend
Foo Rui Fung ty captain obvious
No, he fried it by messing up molex connectors.
I prefer to shoot my troubles with my RGB ram sticks
No, but they're boneless

if u can afford ones :)
I managed to plug the 4 pin CPU power plug in backwards once, double check cable orientation and DON'T FORCE ANYTHING
LOL ouch
Spencer Reynolds I've done that too ur not alone
I managed to miss the PCIe slot when installing a GPU once lmao.
Vhox what did you plug it into lol?
Spencer Reynolds Me 2
Had a friend once dismantle his entire PC when it was just the power button the whole time
In my recent build my resetpins in the front of the case were connecting causing the PC to boot loop without getting into POST....
@@Psyche-D I once plugged the power button into the reset header and the reset button into the power button header
@@BenCos2018 LOL I hate those reset and power pins, they are literally identical and so easy to mess up if you aren't paying attention.
I believe this might be the same thing happeneding to my PC
How do you fix that tho? I know I’ve wired everything correctly but nothings working. Nothing turns on.
missed the first thing clean the pc of all dust etc that could be the reason the ram slot does not work
Don Marr thanks man for tip 👏🏾
Lmao thx
My pc hasn’t been working for a while now. Looked around for a while. Still nothing. I was about to buy a new cpu when I watched this and turns out my gpu slot had died. You saved me a lot of money.
I would add, that while a computer would likely POST with no cooler, most mobos will not post unless they detect something plugged into the CPU_FAN header.
I'll give ya a LIKE for the thumbnail alone.
I didn't even have to force the tears.
They truly are tragic times. We've all been there. (staged for videos or not ha)
Science Studio sometime is just the output Cable some monitors r set to VGA or Dp and if u plug in HDMI it won't post...u have to set ur monitor to HDMI or whatever default port it supports for the time and ur good to go. I had the same issue and I was just about to return my gtx 1070 and my mobo, but I just tried that solution randomly as I was exhausted troubleshooting each and every part and it worked. Lol.
AMD didn't give you an R3 sample? Guess that using a 7350k as a box opener isn't enough intel hate.
Its because he openly trashes companies/products on their flaws, because remember, if youre a big company and make a shitty product people arent aloud to call it bad
It probably because he is honest
One additional thing is a improperly installed riser stud grounding out the board!
yes! that was my problem.
MyWasteOfTime is a riser stud the little metal part in on of my places that were I'm supposed to screw in but I can't because there is a tiny metal thing with my board
Vix i dont know what you mean but there is one that you cant screw in
Elite Gaming oh well dude my PC won't turn on and it's newly built :-;
Please explain
me when my pc doesnt boot for the first time:
this aint the first time my pc didnt boot.
DBEPIC wait
After 8 months, I decided enough is enough and disassembled my PC and tried to clean it thoroughly!!! After an hour-long Deep Clean, When I put together my rig again, I was started getting boot loops.
Oh boy, I could not pick a better time to screw up my PC as my area being COVID 19 hot zone is completely locked down with 2 hours allowed for shopping essentials and I said to my self what a wonderful world!!!
This video proved to be a great help as I followed your step by step approach and able to fix the issue after reinstalling CPU as well as fixing a few missed wiring!!! Thanks a lot for this great video and TOM'S HARDWARE link!!!
Don't forget to unplug the front panel LEDs, sometimes they can short out and cause a PC not to POST.
Did u experience this? Did it fry all the components on the mobo?
@@heyitsdazy Never had it kill anything and usually the PC will post fine with a dead LED hence why people don't even check, but it will brick some boards until you unplug it 🤷♂
This video saved my friend and I hours of disassembly and testing and reassembling. Very helpful
When your one of the only big youtubers that uses ryzen personally but you dont get a ryzen 3 sample
Robin Clarijs you mean 7700k?
Robin Clarijs Well, if you have the intel laying around and it has better performance than the r7 1800X (like the i7 7820X does outperform it, and the previous 10 core intel CPU's probably did too), than why not use the best CPU you have at your disposal instead of the CPU that is currently popular in the community? That is like having a gtx 1080 or 1080Ti having around and than use the rx 580 (which performs between a gtx1060 6gb and a gtx1070) just for the sake of pleasing the nvidia- bashers...
Brecht Schatteman the cpu is not popular, did you not see his video on why he is using it? It's so he does what he preaches, if he's gonna praise the 1700 for it's value and that everyone should buy it, why doesn't he use it, of course Intel offers better but at a much higher price, and while he might be able to afford it, the majority that watch his channel can't.
FruitCakeTech And because most people are watching his channel can't afford a intel X-series CPU, he has to use the r7 1700? I bet even most people can't effort that, so maybe he should stick to the 1600 which is preached as the best bang for your buck available now. The 'do as you preach thing' has more to do with belief than with scenario's like this, I would link such a saying more to fanboyism than a real tech channel. Why? A tech channel does not only have to think about what the viewers would use in their case of content creation. A tech channel would also look at what gives the best performance for the use case that they have available. I am not saying that he has to go buy a 7820X or 7900X, but look at what they have available. I don't know if R7 does outperform the 6th gen 10 core CPU, but if it doesn't and you have that 10 core CPU laying around, why not use that instead of go out and buy a R7 for content creation. Of course he can still preach that the ryzen lineup for the moment is the best bang for your buck available, it doesn't make him have to use it. How many car guys preach about BMW superior handling but still don't use a BMW as their daily driver? I for the moment am pro android but I have an iPhone 6 which does work just fine, but because I am advising people to go buy a new android if they ask me what they should buy, that doesn't make me have to buy an android. Of course it could prove my point and I could try to get RUclips views with titles like "why I switched to android and why iPhone sucks" but that is all not necessary to prove my point. I don't know this channel enough to know what he used before the R7, if that setup needed a replacement or the R7 is a big upgrade than it definitely is a great way to show 'do as you preach'. But if the R7 only performs on par or worse than his previous setup, than it is not showing 'do as you preach' but more showing either enough money to throw out of the window or a certain degree of fanboyism. I know this channel enough to know that he would try to avoid fanboyism though, their are other channels that don't try to avoid a bias. The reason I started following this channel a month ago was because he tries to be unbiased and can admit it when he is wrong.
Brecht Schatteman your right, but it basically does on par with those cpus with a little overclock, and watch one of his videos, I forgot which one it was, he explains why he's doing it. So even if it's not the smartest thing, I applaud him for making a bold move.
If your motherboard heat sinks aren't getting warm on boot, it's likely dead (i concluded this on my broken motherboard)
I went through the troubleshoot up to where I should bypass my video card and connect my screen straight to my motherboard but there was no where to connect my cables so i was unable to illuminate that. This might be my next clue. Thanks
I used to work at a PC parts/repair shop and this is some sound advice. Almost exactly what we did in the back when a system wouldn't POST.
One quick thing to try: pull out all RAM and expansion cards and re-insert. Sometimes oxidization on the copper pins causes problems and the heating/cooling/heating/cooling of a PC over time cause things to become un-seated. Re-inserting cards and RAM can 'scrub' oxidization off the copper and forces a re-seat.
Actually, removing any peripherals beyond the essential is a must. On my first build, I had mistaken a Floppy drive plug for a fan one. Somehow it must have shorted something, and wouldn't even turn on. When I unpluged the fan, everything booted up fine. So unplug everything that's on ur mobo, except cpu power, mobo power and gpu.
UNDEFINED_// ILLUMINATI do u need a graphics card for the pc to work? Cuz I’m currently building a pc and I don’t have a monitor yet but I wanted to test if everything is working but when I press the power button it turns on for a second and the cpu and system fan comes on then it shuts off and no I don’t have a graphics card in yet, but I don’t wanna continue spending money on parts if I know it’s not gonna work :(
@@castashin u need a GPU for the PC to post
Ben C this depends entirely on the cpu. If you’ve got an iGPU (integrated gpu) in the cpu, you can use the DisplayPorts/HDMI-ports/vga whatever you have on your mobo to post and even boot. However if that works then most likely the gpu is at fault. Could also be the pcie lane
Hey Greg!
Just to let you know, it can also be a faulty CPU, i've seen one that caused 2 RAM slots not to work, while the other 2 slots were fine. :) Another thing to note is that shorted USB will cause the computer not to turn on at all, happens to me much more ofter than i'd like to.
I found that my motherboard kept shorting because of the case standoffs created a short which turned my PC on and then off again. Then the PC boots and works for 2-8 hours and repeated the process. I had no choice but to buy a new case which worked perfectly. The old case is working with my newer machine which makes no sense. Anyway, great channel man. Keep us learning and I'll keep this Computer Fire burning inside me.
I once had a PC (Back in the pentium 4 days) it wouldn't post as long as 1 specific USB port was in use...
if i used other USB ports (or none) it was fine.. This meant, coz i used a USB mouse and not a PS/2, the troubleshooter in the store spend 3 weeks fixing it, coz he didn't use usb peripherals...
eventually it the issue was found and i got a new mobo.
Learning by failing, i guess. Just leaving that "tip" here. test things without having usb and other peripherals plugged in. then you can always plug them in, if it posts and see how/if that works
Mikkel H wow! This is a pro tip. Really wish I could up vote you more!
To expand on your advice, I'd say it's a good idea to see test your PC with everything removed that can be removed. Remove Fans, graphics cards, all pcie cards, sata connectors, use one USB port at a time, use one ramstick at a time (test your 1 ramstick in a different computer that is working). See if it POSTS.
Then start re-adding each component one at a time.
Look it up with peripherals to see to show it can power all the crap it needs to power.
who ever is on a IT course would love greg to be your tutor 1000%
have been watching jay and linus for years and u just say things different and more professional
Where the fuck is Ryzen 3 coverage?
Didn't receive a Ryzen 3 kit.
Jason Rufener How dare you mention Ryzen, I am an Intel shill and Ryzen is one of my trigger words, please be considerate to us Intel shills please. Thank you for understanding
Science Studio Lemme guess, either AMD does not like you or you arent big enough
Much smaller channels receive samples, so it must just be that AMD doesn't like me ;-)
Science Studio damn amd, want your honest review on ryzen.
One more tip: If you are using an SSD and it occasionally decides to die and come back to life after unplugging and plugging back in, it's actually the PSU that's bad and a fluctuation on the 5V rail puts the SSD in power surge protection. I know this because I changed an SSD and a motherboard just because of this weird symptom.
Great Video. One more thing I would recommend (you may have mentioned this and I missed it) is remove all peripherals. If you get a post, then start plugging in peripherals one at a time.
I always turn on subtitles(auto-generated) everytime I watch your videos. Damn you speak faster than jay or linus:D
JayzThreeCents Studio speaks normal
When Greg said to drink caffeine, he definitely wasn't kidding. I used to live off of coffee when I was working as a computer tech in a small repair shop.
Oh my god I know this is late but your giving me ptsd. I worked at a computer shop when I was 15 I loved it and hated it. I used to get treated like shit because I was young and would often find myself getting yelled at by customers. Alot of the time it was the people that thought they knew everything about pcs but made a very simple and minor error that anyone that's ever built a pc wouldn't make. Like forgetting mobo power/cpu power. It was great because I was broke and was gaming on a shitty pc so I loved benchmarking customers pcs
A year after starting PC building and I just learned the "Post" is an acronym. Not even LTT taught me that. If I wasn't already subbed, I would be now.
I'll share a PC troubleshooting nightmare story. Long story short, motherboard w/ bad socket fried the CPU. Shortly after installing Windows, random BSODs would happen with different error codes. Swapped the motherboard not knowing that the CPU was already fried from the first one. Had to take it to a professional who diagnosed the bad socket on mobo #1 and that the CPU was now dead. It was a friends build that I helped put together and troubleshoot the issue. He ended up eating the cost of the diagnosis and dead CPU, BECAUSE HE THREW AWAY THE BOX RIGHT AFTER HE GOT THE THING! NEVER DO THIS! KEEP THAT SHIET FOR AT LEAST 30 DAYS! That's the moral :)
Or keep the box forever is the best thing
What really happen was the i5 shit itself when Ryzen 3 released
Jobu jishuko those two aren’t even competitors. More accurate would be Ryzen 5. Ryzen 3 is an i3 competitor in both price and performance.
IN performance a r3 is equal to i5 4460 or 4440
HAHAHAHAHAHAHAHAHAHAHAH
About to build my first PC here soon, perfect timing lol
Same here, have literally every part except the CPU, hopefully newegg is fast :P
Bruce Austin appreciate it, haven't gamed since cs 1.5-1.6 but battlegrounds got me interested again.. figured perfect time to build one finally
Greg, you're absolutely right about making sure the RAM sticks are pushed all the way in. I've had that happen to me with the last computer I built and, to my shame, it took me a while to find the reason why my computer kept beeping like crazy and wouldn't boot.
Love the vids, dude. Keep it up!
Directed here from a Fix or Flop. Great that it became an official series!😁
I've had it as simple as the HDMI chord was not all the way into my graphics card
Wow man... I was building my first gaming PC. I didn't know my graphics card had a slot for the HDMI because it had rubber plugs in it which I didn't even know it was removable. So I saw your comment and wondered (wait... An HDMI can plug directly into a graphics card..?). Sure enough I took the rubbery things out and plug an HDMI in and there it went, it finally turned on after 2 days working on it. I'm not surprised it was so stupidly simple that I feel like dumbass. Thanks a bunch!!
Profile picture checks out
A few months ago I built a PC for my friend, and it just wouldn't give any signal to the monitor (monitor only had a HDMI port) and I searched up a bit and I found something simple that fixed the problem:
Unplug PSU from wall, turn the PSU switch off and then press the power on button on your case/mobo and hold it for 1+ min and voila it got fixed.
Never understood wth was that and why it happened but I was glad it was that easy to fix
Bruce Austin Oh I see, thanks for letting me know
Thanks
How to watch Greg's videos:
Step 1: Like the video
Step 2 : Lean back
Step 3 : Actually watch the video
Step 4 : Enjoy!
You're the best, man!
I personally have just recently ran into a problem where my pc seemed to not be getting any power. However, I knew that my power supply worked because the computer randomly booted after a few hours of messing with it. But the next morning it didn't boot up and I took it to a repair shop and it booted for them. Well, the other day it wouldn't boot again so I looked up motherboard temperature sensitivity on an off hand chance. Well, I figured out that my board is being temperature sensitive, most likely because of a capacitor swelling because it is a cheaper board. But to start the computer from a cold start all I have to do is blow dry it for like 30 seconds to a minute and it boots right up and plays perfectly. It was very frustrating finding this issue because I spent hours with my computer disassembled and it was starting to affect my day to day life. But thank God for forum posts!
I had such bad expierience with AsRock boards. Literally every board i bought failed after 1-3 years...
Tell me about it, I think mine just went dead that’s why I’m here. H81 Pro BTC 2.0, checked everything else other then board and PSU
Joseph Kay Damn. Mine’s just over a year old. Hope it doesn’t die🤞
@@iambicpotato2198 I can actually give you an update after 3 years. The new ASRock Boards don't suck as much anymore in my experience. The only AM4 boards that were failing me were from MSI
Indy Thank goodness! Which board are you using now?
@@iambicpotato2198 An AsRock X470 Gaming K4 for my gaming rig and an AsRock X399 Taichi for my Server
To troubleshoot your PC, use a Mac...
Said no one ever
And neither did I.
I Love how you distinctly pointed out that you didn't due to it being that big of a cardinal sin in the pc community.
@volkswagenginetta Only the children of the PC community think that
well yes but they are generally the loudest and an outsider might think that represents us all for a quick glance
I made a hackintosh after my computer broke
i do a lot of these steps with troubleshooting, but there were a couple here i didnt think about, thanks Salazar! you always manage to keep it fresh with this channel =)
Thank you for the step-by-step suggestions for troubleshooting and for posting the link, too. I bookmarked that link, and added this video to my "PC Build Info" playlist, too.
And, yes...coffee is ALWAYS my first step in troubleshooting anything.
That feeling when this video confirms your board is dead on arrival *sobs*
wibblemu9 😰
I think i managed to get 2 dead parts
I just changed my cpu and it would put me in a boot cycle but there was this thing on the back that say 150 and 250 so I flipped it to 250 and it would just keep running. And I reset cmos but I only have 2 pins on mine and no jumper
very knowledgeable and technical i loved this video even if i dont have the source to change out parts, this guy hit every section of the pc dead on
i came here to brush up on some things for a job interview, but i was pleasantly surprised to see a such a cutie explain how to troubleshoot POST.
It could be as simple as (finish the line):
Your display is set to the wrong input.
Don't ask how I know that can be a problem.
- Gnomes
- Cosmic rays
- The magic blue smoke is not secured properly
Seagull 78
You’re hitting the reset button
Stop trying to use the USB port to turn it on
Dude, it’s not even plugged in
Is your power strip on?
Is your power supply on?
You installed the power supply, but didn’t plug anything in... dumbass
You have a ryzen cpu but non ryzen compatible ram
Arctic Line Loool that happened to me too😂
You wouldn't believe it but animal urine does a good job of killing computers too. Those random moments where you just have no idea what killed the machine , or kids spilling water that quickly evaporated before you realized too.
Yanku Marrah hoho I don't believe it buddy. A liquid? Destroying a computer? No way.
One step you might also want to try is removing any usb peripherals. I used to have a Bluetooth adapter that caused generic bluescreens.
Just wanted to add a comment to the boot drive testing mentioned at 8:04. Not quite the same situation, but a few years ago I was upgrading from X58 to Z97. Most of the components were new, but I opted to keep the same case and SSD since I was happy with them. Did the usual test the core components outside the case to validate that they worked before doing the rebuild. Once complete, the system failed to POST. No debug LED on the board so had to do it the old school way.
Took a while, but after stripping it back to the core components (Motherboard, CPU, RAM and PSU) just to get the system to POST, I finally found out my SSD was causing the system problems. Tried it again in my X58 configuration and it was fine. A quick google search later and the answer was my some what old OCZ Vertex 2 drive was not compatible with Z97. So it is possible to have a drive cause a system to fail its POST, but not very likely.
Hey so what Cooler do you recommend for a ryzen 1600 to get it to 4.0 as quiet as possible. Love your channel. Thanks
Agosto D'Andrea noctua nhd15
Agosto D'Andrea any 120+ AIO or the Cryorig H7 and and any higher tier Cryorig
Agosto D'Andrea Kraken X61 if you're going for an AIO and Noctua NH D15 for air cooling
Water cooling will get you the most silent cooling....
Matthew Mirchandani depending on what you mean, custom water cooling yes, aio no. Take for instance my skylake build, 6700k with corsair h110i, the pump can be surprisingly loud, louder than a 3.5" hard drive.
"Can't trouble shoot my PC cause I don't have one"
I still remember when my pc shut down again and again, change the ram, power supply and graphics card and in the end the problem was the sata cable from my hard drive.
Great troubleshooting video Greg. Wish I had these tips when I was in IT back in 98.
In bed with a fever watching this aha trouble shoot me!
BigPaco213 hope you get well soon : ) .
I have checked other forums and such with no luck... but does anyone have an idea what would cause my pc to take like 30 seconds to post?
Maybe you had too much software installed that will activate when the PC boots? Try disabling them.
Or install CCleaner to clean your pc.
An old HDD
Try unplugging components one by one. Ormaybe it's just old. or try checking the bios.
I just built it a few months ago. It has a Ryzen five 1500X and a SSD in it. As for the store for, I'll check, but it doesn't have too much on it. It has a black screen for about 30 seconds then the bios screen, then the boot screen.
Probably just a flaw in motherboard manufacturing. But it doesn't sound like an issue. Cant possibly be a hard drive as that doesnt matter with posting
1st thing is to ATX reset the PSU. remove the power cable and hold the power button for 30 seconds. You don't even need to open it up to try this, it only takes a minute and it does fix a relatively high amount of POST problems.
that was the best thumbnail I have ever seen
Not enough RGB, disliked
GG me
Now I`m scared of building my new Pc :(
Don’t be! Just take your time with it. Greg has some great videos on building, as does JayzTwoCents. Give them a watch until you could just about narrate them yourself and then give it a go!
@@Just_Call_Me_Tim Thanks for the late answer :D.
Just built a pc a few month back myself, so yeah ;)
The best advice, remain calm. With a leveled head you think much better.
This was very helpful. In my case the VGA card was not fully connected, so I checked it again and now it boots fine!
I really thought my CPU was dead
Who else remembers the stuff that happened with the NZXT hue+... Just me... Okay then
Mac the dead meme of computers
thank you man, really helpful tips. Old mobo that won't boot came back to life using different memory slots! I'm really happy and i had to thank you.
8:54 "Even if you don't put any cooler at all atop the CPU and you just try to turn the thing on, usually you'll get a post, and your PC might even stay on for a while, if it's just gonna thermal throttle hard core … it should still run for a few seconds at least" -- Carey Holzman did a video a while back where partway through the video, he took the stock heatsink off a Haswell i3, booted it up, and ran Prime95 for several minutes. (The system was on a test bench, not in a case.)
Had a similar computer with the same issue. Turned out to be that the CPU had somehow lost it's ability to run with quad channel memory... Replaced motherboard, CPU, and then the RAM as well. I'm seeing this issue a lot more lately with the Intel Core i5/i7's from 6th gen on Z170 boards
I respect the fact you have a Mac. Best of both worlds. Colleges tend to lean towards the Mac side of things, if you even use it for college. It is the only reason why I got my Macbook Pro
FWIW, a dead mechanical HD certainly can cause a POST failure, usually of the "It turns off as soon as I turn it on" or "it won't do more than make the fans twitch" types. I've seen this happen many times.
A short in the motor or electronics can drag any of the supply rails down to ground, hence no "power good" signal. Dead giveaway that this is happening is when the drive's power connector gets warm to the touch even though it's only had power applied for a few seconds. The same could apply to SSDs, although I've never seen it personally.
Simplest test: Unplug power cables from *all* drives and if you get a POST, try plugging in each drive one at a time (after powering down, of course) and see which one causes the problem.
One other step is move your SATA plug into a different slot to see. I have had it so that the SATA port on the mobo is going bad, and will cause an error with booting and staying on. The board is trying to access a drive that it can't always get the data to and from and does sometimes cause errors. It can be as simple as the cable came just a little loose, or that the plug is going bad on the mobo or drive. Just know it's one I have had that you may overlook
Haha, very relatable. I spent like 3 hours troubleshooting my PC only to find out that the ram wasn't pressed in all the way.
So a couple things. First, you can grab a power supply tester off of Amazon for less than 20$ with a digital display that is very easy to use to make sure your power supply is working properly. No need to buy a whole new PSU just to troubleshoot a POST issue(if it were turning off under load that would be a different story). Second, a faulty hard drive controller or other ICs on the drive (BIOS chip for example) can absolutely prevent a PC from POSTing, It's happened to me more than once with shit seagate drives. There have even been recalls and class actions over this for drives with especially high failure rates.
Most of this was pretty good, generally speaking, you want to start with the quickest and easiest eliminations with troubleshooting and work your way to the more time consuming procedures. One thing I would add is to check any AIO cooler or open loop pumps and ensure they are working still, high temp states on that initial power surge can trip protection features that can also prevent POST. Also, start with unplugging any non-essential USB devices.
the suggestion for trying each ram really helped me out, for some reason my pc refused to run dual channel. I had to update the bios to get it working
Hey Salazar, got a case for you, see if you can help me out. I'm been building PCs for ages, and from all of the weirdest stuff I've ever came across, this might be the weirdest of'em all, check this (keep in mind that I've already done all the indications you made in this vid):
- Primary basic Gigabyte brand Intel board with 4x4 GB DDR3-1600 Corsair Vengeance LP XMP compatible sticks. (Board has no bent pins)
- Secondary Gigabyte brand Intel board with 2x8 GB DDR3-1333 G.Skill value-rated sticks. (Board had bent pins once, I repaired it myself pretty much long ago)
- Borrowed ASUS Z77 board with 2x8 GB G.Skill TridentX 2400 MHz CL10 CR2 1.65v w/XMP profile
- 3 LGA1155 processors: i5 3570, i7 2600K and i7 3770.
- All boards are made for Ivy Bridge (B75 and Z77 SB)
Diagnosis:
- System won't POST at all on primary board with the i7 3770 and all 4 sticks, but will with only 3. DIMM 1 slot empty.
- System runs perfectly fine with all 4 sticks on primary board, both i5 3570 (XMP enabled) and i7 2600K (XMP default disabled, can't enable it, 1333 MHz)
- Secondary board with i7 3770, this board has 2 DIMMs, both used with it's described RAM sticks, POSTs and works well.
- i7 3770 on borrowed ASUS board works fine with 2 out of 4 DIMMs (all DIMMs tested), though it won't POST on full 2400 MHz speed, even with 1.65v. System runs just fine with altered XMP profile: 2200 MHz, CL10, CR1, 1.55v
I really can't come with a conclusion. All DIMM's slots works, all RAM sticks works, all CPU's and board works. Just can't figure out if i7 3770's IMC is failing or just trolling.
All help is deeply appreciated.
You get a good idea what's wrong by the error code beeps from the case speaker. I'm really surprised it wasn't mentioned in the video.
Sometimes there is power imbalance after a PC is not used for long. Disconnecting everything and re-connecting each cable fixes the issue. Unplugging the PSU also fixes the power issue
I hope thats my problem i let my cpu set for a few months, went to get back to gaming and now no signal! I messed with it for a couple days now and i still sitting here watching you tube videos...im Gunna lose it😡
I really prefer the good ole "Remove bios battery, keep power button pressed for 10seconds and put battery pack in" reset method :D
Hello!! I would like to comment what a great help your video was for me. It was when I was switching displays when my computer suddenly stopped displaying anything after the next boot! The solution to this was your cmos reset option suggestion. I’m thankful for your help!
I don't care what people say Greg. That Mac is a nice sexy looking addition to your desk
Good video for new builders (and old ones that haven't done it in a while).
For those who just want a step by step summary:
- Get a drink
- Check cables, assuming those are all fine (if it's your first time building, they probably are because you will have spent a STUPIDLY long amount of time checking them all first) start pulling parts out
- Greg says check RAM first because it's common, I say check HDD and/or SSD first because it's easy ;)
- Check every other part, if doing it Greg style start with most common things, if doing my way work out which things are easiest to take out (RAM is probably next for me but it takes awhile to check, then maybe GPU)
- If nothing is working uh
- Go contact someone who can physically be there. Try installing an OS. Check if you have a CPU installed. Legitimately all things I've seen people do.
This might be an old video, but I use this video recently for a guide to revive my dead PC. Thanks it's really helpful
Also just make sure if you have a Kaby Lake Cpu you aren't putting it into a Sky Lake Mobo without having already updated the bios. If you don't have a Skylake Cpu (unless the mobo has some sort of quick flash) your only option is to just buy a cheap Skylake CPU, use it to update the bios, and then return it.
You are amazing!! Thank you for explaining this so well! Your first suggestion fixed my issue.
Been using my PC for years and then one morning I had a solid red CPU light on and no monitor signal. My motherboard didn't have a CMOS-labelled jumper or a button. So, I took the CMOS battery out for 5 minutes to discharge. Placed it back in, did a test run with the tower hooked up only to power, couple lights flashed and disappeared, and then it settled on BOOT_DEVICE_LED. It was ready to be fully hooked up :)
YOU HAVE NO IDEA HOW MUCH YOUVE HELPED ME
Thank for the help. My issue was the motherboard battery so check that as well.
Dude... i had this problem 1 day ago an i had to figure out what the hell to do... i thought my mobo was dead for the same reasons you said. lucky me, no part of my PC was actually dead, i think my problem was that the motherboard was not well adjusted to the case, it was missing some screws and it could be touchng the metal and causing it to crash sometimes until it didn't "post" as you said.
Adjusting those screws and reconecting everything again fixed my problem. Thank you for the video, it was most informative and is good to know i actually did something right here, im just a newbie with the PC building.
Funny thing, my PC is very similar to this one, except my CPU is an i7 6700, everything else is almost the same specs, just different brands,
I've seen some unusual stuff. There was a laptop that didn't post because of the dead hdd and an other one not posting cos dead CMOS battery. I'd recommend removing anything that is not essential for posting. You have an IGPU? Great remove video card etc.
12:04 I did that exact same thing one time. I was looking for the problem for about 3 hours and got so frustrated with myself until my brother came over and pressed the reset button which turned on the PC and I felt stupid. At least I will never make that mistake again
the first thing i usually do is remove anything thats connected usb ports and accessories like case fans, dvd drive, i have had case fans shorting, hdd power supply loose, molex converter being the culprit most of the times. so i usually disconnect everything and start with just the cpu and ram see if i get post then connect hdd and so on one item at a time to narrow down whats causing issue. sometimes all it needs is cleaning the dust off and reconnecting everything
One could also power drain the system. Sometimes rogue current enters the system and cause the safety system to trip.
Unplug the PC from the mains power. Unplug all external peripherals (Keyboard, mouse, monitor, etc). Then press the CPU power button for 30s or more to drain the CPU of the rogue current. Then try booting it.
Most people probably don't have multimeters or old ohmmeters lying around.. but they're the best alternative to test resistance and current rather than buying brand new hardware. If anybody is going to work with PC components regularly, then I would invest in a decently cheap meter personally. Also with proper probes you may even test at the smaller component level.
2 years later still using this video as a guide. I believe after all the troubleshooting I think the cpu was DOA. The new ram was able to light up, cpu cooler and case fans turned on, and graphics card fans were on. I just was getting a black screen
This can also be a mobo problem tho, depends on other symptoms
If debug LED's are off and you get no display, well, after you double-check everything, it's probably the mobo
If the CPU debug light is on, your BIOS supports the CPU, and your 4/8 pin is plugged in, you can be fairly sure it's the CPU
Note that CPUs generally not break, bent pins can happen though
Throwback to when I thought my PC was broken and the ram sticks weren't all the way in.
Edit: great video subscribed
I appreciate it. Thanks for watching.
TMB xd lol I had the same problem when I built my first pc
The RAM not being pushed far enough happens to me all the time. It's the first thing I check now every time I get no post. Also the CPU swap in and out thing happened a couple of times.
Simple enough. It’s pretty straightforward. Good stuff. I’ve always had a habit of actually removing the cmos battery lol even if the new motherboards have an option to reset it.
Thnx to u and jay and jasus naxus now i run side business to build pcs and its fun work for me hopefully i can make a store soon
I had an older PC I did a BIOS update to and for some reason, it would boot very slowly, and the drives would respond slow AF. I went as far as getting a different drive and reinstalling the OS only for the same problems to occur. I checked EVERYTHING, but the recent internal card reader I installed a couple months back. I disconnected it from the USB header, and everything worked as it did before. I even reconnected the card reader and it worked fine. It really does pay off to troubleshoot everything...
