Computer randomly shuts down and turns back on by itself - How to diagnose a faulty PC power supply
HTML-код
- Опубликовано: 31 июл 2024
- Having stability issues on your computer especially while gaming? random reboots? computer turns off and turns back on? most probably its your power supply which is faulty, however you should test other components as well like RAM and GPU on another computer. So in this video I show you how to test the voltages on a power supply.
Buy the Corsair VS550 550 Watt power-supply:
amzn.to/2vU0EmM
Multimeter:
amzn.to/2etNFC3 (FLUKE)
amzn.to/2xGmb4f (Mastech)

This is very frustrating, especially the hopelesness feeling after it happens multiple times in a day

For anyone wanting an update, bought a new power supply, it happened again, $100 down the drain, messed around with pc battery savings over the co ur we of 2 weeks and now it’s fixed

So what is the solution?
Thank you for this, finally. Someone who gives answers instead of posting a video saying they have the same issue and asking others for help
It happens to me even when I'm just watching a movie not only by playing a heavy game like horizon zero dawn, So what i did is i removed my gpu that is gtx 1660 super Evga and tested my pc with the integrated onboard graphics that is intel hd 4600 nothing happens even when playig light games but when i plug in my gpu that is gtx 1660 super pc keeps restarting itself with a buzzing noise/sound. Can anyone help me?

Thank you very much for the explicit video , I watched many videos before this, but your video was the most clear and direct to potential solution.
You are right on the money! I was having this problem and after watching other videos, I was even more confused. It appeared to come down to replacing something and the power supply was a lot cheaper than the other components. I replaced it and now no problems! Thank you as you were right.
Sorry for bother you. But i want to know that your earlier power cable was okay? Though your power cable is okay you use a new power cable? Is it like that?
@@ummehafsa243 Thanks! The cable itself was fine, it was the lack of power causing the problems. One thing I learned...you can never have too much power but lack will cause problems.
I’ve been searching for a vid like this for a long time! I’m glad I know what’s most likely messing up my pc now, thankyou
You are not alone 😿
Thanks man you really saved me
You deserve 1 million subs
Well done sir on a video that gives me answers to my problems and not a could be or maybe. Top work
So much nerves were lost because of such an issue, and I did suspect that my Power Supply was the possible issue. Your video just futher confirmed it. Big thanks from Russia.
Simple, clear and to the point..for that, new sub.....mine restarts everytime i start playing fs2020....the other games play just fine
i had this problem it was super random. I tried taking out the ram, cleaned it and placed it back but it still shut down i thought it had to be the power suppy till i tried placing the ram into the two different outlet AND IT WORKED!! THANK YOU!
I like the temp reader in you 5 1/4 drive bay!
Man this issue has been driving me mad for the past 4 months. A friend recommended to me this video. Thanks man.
Hey, I hope you were able to fix your PC? 😊
I can tell your a big co puter fan i hope one day u get blesseed with a really nice set uo so you can teach us all more tips. I almost shed a tear when u said u couldent rub tomb raider lol
Really awesome troubleshooting video man.
Most helpful - my CX750M needs then to be replaced. I have seen other videos that this particular model is giving issues.
Extremely helpful man!!!
I've had this issue for a few weeks now and I've gone as far as replacing the thermal paste on my GPU because it hadn't been done since factory. That helped a lot because the original thermal paste was rock solid. Once I put my system back together, it was still doing it. Mine only restarts when I'm playing games which is why I thought GPU at first. I'm going to buy a new PSU and if it works, great, and if not, I'll keep the PSU and start building a new system piece by piece.
Me too
It's so annoying I restart the computer a million times a day
@@epid8671 I still haven't tried a new PSU yet. Honestly losing all faith in my PC at the moment lol
@@MrHowardMoon same mate. im losing hope too
@@epid8671 Replaced my PSU and the problem has gone. Games also seem to be running better in some areas.
Can you please tell me ? About my problem... actually I brought a gaming pc which has 16gb ram 2666hz, 1050ti gigabyte that doesn't take any extra power and i5 8th gen running with cooler master 650watt, but the problem is while turning on sometimes later it's off then on , cause it's related with GPU, it's not working GPU doesn't supply signal to monitor or turn on , I have tried many tricks but not working, I just replace mob battery then open pc then I have watched my GPU fan turns spinning but my pc turns off it also turns off so that I ask you if my power supply damaged or not please help me kindly!!!
Yep, the power supply is bad. I had the same issue and my PS was no good. As soon as it was under a load like playing a game it would shut down and turn back on.
Thanks mate mine doing the same right now whenever I play game, so now I know what's the problem. Will buy a better psu on eBay.
@@itachiuchiathesoulking6553 and did you? And did it fix it? Thanks!
Mine just does it without any relation to how much of the CPU is running. Have three tabs of chrome open? Off! Playing Starcraft 2 on high graphics? Perfectly fine for a full hour. Playing Super Mario Sunshine for 10 minutes? Off!
@@MrWin-pj4sg Mine does too.. and it started yesterday. I wonder if you found the solution. I reformatted my build & checked RAM, temperature and problem continues.
I am having issues randomly.. it does not happen when I am on desktop not doing anything. But it happens when I try to run any problem (regardless of what it is).
My build was just fine until yesterday.. so I am pretty sure its hardware issue although my parts are less than 1.5 yrs.. I just bought a new PSU and gna see if PSU is the issue. I had previous build where PSU was the issue.. but it only restarted when it was under some loads.
@@jaydenlee4879 It's tricky for me to tell you if it's fixed or not, but I deleted a LOT of unnecessary files and it's working perfectly.
I'm expecting it to get worse again soon, but I am enjoying being able to use it for now.

Doss testing the molex like you did constitute a test underload? I have never seen that before but it would make things easier.
If this does constitute a test under load I just need to find a free Molex connector to perform the test on correct? You didn't unhook anything to get to that Molex connector right?
I'm assuming I have the same problem without checking the power supply. I added an extra 1 TB drive and after about 30 minutes the PC will restart itself, but I do not get any error reports, it just reboots. With the extra hard drive disconnected the problem doesn't occur, the extra drive may be too much power consumption for the power supply, not necessarily that it's faulty.
Genius , mine have this problem i think its on my power supply too, because i installed it yesterday then my pc shut down randomly, this will very helpful for me thank you so much
love from sri lanka
hey , did power supply solved the problem?
sometimes, my pc likes to earrape me with a sound which is basically knife and fork scratching on a plate combined with nails on a chalkboard and then distort it. i have no idea why, its happened to me twice now and it isnt often. most of the time though, my pc will sometimes restart randomly during or within an hour from startup. never happens when im loading or playing a game. the screeching one has happened while ive been in blender though, but that isnt much to handle. any suggestions?
finally GOT a solution TY
I have problem that my pc might be on like 7 hours before it restarts randomly (black screen comes and instantly after that BIOS text and all those when you turn your pc on and then i need to login again). I have tested several PSU, RAM, i have new prosessor but same model as my old what i sent back to the shop because i tought its prosessor problem but now i have this new prosessor and my pc still random restarts. Could this be motherboar or gpu problem? I thinn not gpu because i have got this restart when doing nothing on my desktop, watching youtube vids and playing. Many different things but i have no idea wich one it is :(

Please make a dedicated video on PC build in different price brackets and from where to buy.
It would be really great
I would love to make a video where I show how to build a basic Budget PC for home and a Gaming PC and maybe use different hardware from Intel and AMD! but I cant, because as an individual its almost impossible to actually go out and BUY PC parts just for a video :( maybe if I get some PC hardware manufacturers sponsors in the near future I would do such a video.
At the moment I buy PC parts from Amazon India, remember to always buy from reputed sellers.
Hey man i have also same king of problem but if i Don't like use the pc for a day it will work fine even under games but if i use it for like an hour or so it start restarting eveb if my pc is under any load its just restart as s soon as i reach windows or even if i enter bios , what cab cause this?
Thanks for this video it helped me a lot!!
Same trouble with my PC, replaced my PSU all working good now
i dont know how to fix or know where to plug in a new power supply maybe we have same problem my pc restart when i play a game ... plz help me
I have this same problem but in a laptop.
Do you think it’s the battery? I tried removing battery and with only the adaptor plugged in, laptop still restarts after approx 30 minutes every time.
what an amazing video man...what a clean and clear explanation and constructively made video
thanks alot
how do you check those error messages at the beginning?
Which is the name of the programm that you used at the start of the video to show you events?
Had the same problem and thought my PC was overheating due to dust at first. After doing research I saw it was a power supply issue. Your video was visual confirmation
J F So it time to upgrade my power supply right? I just use it for like 2000 hour is that normal power supply life time? Or I just use it too much ?some week I don’t turn my pc off at all

3rd PSU corsair vs 550 watt. I don't have voltage checker device so is there other way for checking the voltage
My problem is When Windows Shows Welcome screen the computer poweroff suddenly and start it again but if i enter the bios of mobo it doesn't restart or suddenly shutdown
dude i have the same exact problem like you which lead to a dead mobo. now that i changed the mobo but the random reboot is still there but not that frequent. thinking about changing the psu n i was just thinking issit the psu that is faulty or just my power socket sucks. what do you think?
is it possible that a bad psu can cause the pc to freeze?
what if voltages are good as I monitor with HWiNFO64, And I stressed test CPU and GPU at the same time with powerMAX test for 10min. I ran memory diagnostic test. But my pc restart like your does only if I game. Even if I game it don't restart every time but may be once a day or two. Should I change my PSU?
Happened on two seasonic snow silent 80+ platinum, many other 80+ platinum builds, and now on my pleb corsair.
Yeah my PC just did a random restart for the first time while I was playing a game my pc is less then a year old to lol when it restarted it froze on the log in screen I restarted it again and went into bios and my screen was crackling and it said my GPU was in the mid 70c's and my motherboard was 52c not sure if those are bad or not and I dont know if that was the cause ?

Hi, I just bought a new pc and installed Windows 7 on it. But whenever I start the computer it reaches the welcome screen and then shuts down. .manually restarting the computer again solves the problem. However, once it starts it works fine no shutting down no nothing. Can you pls tell me what the problem is. My specifications are Intel i5 670@3.47 GHz, msi graphics card 1gb, 4 gb ram
hey i have vs 550 als a friend from me so i bought his one by him it was working phine by my not ????
So when I test it with my meter i don't have to disconnect any of my power cables inside thr PC like my components?
I too have the same issue.. my pc turns off automatically and starts again.. but in my case, the voltage stays at 12.07-12.10 while playing the game and still turns off.. and the voltage doesn't drop when the system turns off. It shows 12.13-12.15 when idle. What can be the issue here.. please suggest
thnks alot brother my corsair vs550 was dead and i dint knew what was the issue
I figured my psu is stuffed, its a 860 w corsair from about 10 years ago, pc is always on (except now), mostly ran from a line filtering ups, now it only stays on for about half a second and keeps cycling. It died when i was finishing farcry3 lol, might open her up and inspect some components. was running a 4th gen i7 and 2 1080ti's
Good instructional video mate.
My psu was fine, turns out my bios needed to be reset, then it booted. Now to find out what's wrong with my ax1200i that only worked for a few days.

dude what is my volts are consistently 15 on a 12 volts PSU ? is it still faulty?
My system restart whenever there is a slight fluctuation in power supply. Iam using a vs 650 power supply with on board graphics paired to 3 yrs old Apc bx1100c-in ups which is giving a 30 min backup when power is cutoff from mains also checked battery volts which are 13.41 & 13.22 at discharging state. Please help iam suspecting bios or psu problem
Is it normal to restart my pc automatically. and my pc was only 4 weeks ago and all its parts are new and my psu is 450 80 plus bronze inplay. but when he restarted I did not use him even when pressed
I already have checked everythng.. Changed the SMPS and the cooler as well.. But the PC still restarts, is there anything else which needs to be done?
I use 650w psu its from cosair i think i use i3 9100f and rx 570 i used to think it was over heating issue but my cpu temp is 60c and gpu 50-65c and my gpu draws 105w and i dont have 8 pin connecter i only have 1 8 pin connecter which i use to power my cpu for my gpu i use 6 pin but it requires 8 pin it just works fine but recently it like restarting to much any idea how can i fix it?
Hi, my psu has same voltage with yours 10,8v with multimeter for 12v, but when i check in the bios it say 12,114v for 12v+ pin. Which one is correct? Btw i have same problem with you
thank you. mine had this problem too. I changed my power supply unit and now it is all ok.
Glad I could help

Hey tech guy charlie please help me resolve my problem when i run like the lowest game like roblox i just play that game than when the game is while running i hear a crack noice from my power supply than shut down please help me resolve it
My power is 11.70v when nothing is running and 11.40v sometimes 11.10v when i play games you think this is low enough to restart my pc?
For me it freezed the game and reset .now I can't even boot into bios anymore,it just resets all the time. You think it's PSU?
im having the same problem...my pc restarts randomly when playing games or im on youtube. ive changed the power supply and still having restarts...any other ideas??(ive changed my rams/ssd)

Bro, my pc reboots with saying "power surge triggered". I just bought my new power supply. Is my power supply faulty? (Some days ago I dropped a screw in my cpu but I haven't found that yet. Can this be the reason for it?)
Is it still possible the PSU is the problem even without the kernel power error? Mine has been doing this with no blue screen and no error in event viewer, other than the one that says it shut down unexpectedly
@am1RRR MvM I ended up getting a new PSU and that fixed it, so I guess it is possible
Bro you are awesome 👍
I will definitely change my PSU I will buy corsair vs450
Currently I have a cheap 250watt psu .
Dont buy corsair vs series i have 650 and still problem persist buy rm or cx series!!
Still bad psu because I had the vs650 & still got restarts black screens, has to do with quality of the psu, that delivers perfect voltage I fixed mine with a superflower gold PSU, OC3D from UK had a video about it showing about the peek voltage that's when I decided to buy it even if it was a unknown brand for me
I have a question, I build my Brand spanking New computer today, The case is a Lian Li Mid-Tower Chassis, it has a ASRock B450M PRO4 AM4, Pny Cs900 480GB SSD, Seasonic S12lll 550W power supply with a AMD Ryzen 5 2600. I got almost all the part but the ram , I installed all the cords everything single thing that was needed to be plugged into a mother, and for some reason it's power cycling, and when I found the problem, it was the CPU connecter that is plugged into the top-Left of the board and when I take it out the pc stops power cycling, is it because I have no ram because I need help!!
Dude you need RAM to make your PC work! Without the RAM it wont post!!!
my laptop randomly freezes sometimes, i happens more with linux but occasionally with windows. can u tell what software you are using to detect the cause of the restarts, it might help me in troubleshooting
So it happens not only on Windows but on Linux as well? Probably your hard drive is dying, it can be something else but I also had a similar problem on my laptop and it was my hard drive which had a lot of bad sectors I cant be sure unless I actually have the laptop in front of me for diagnosis! What you can do is on Windows download this software called HDTune to check if there are any bad sectors on the drive. Do you have a spare laptop drive to swap for time being? that is the easiest way to figure out if something is wrong with the drive.
www.hdtune.com/
I use the built in Windows event viewer to check errors and then you can google them to see what they mean.
what kind of event viewer are you using? Mine is very different ??
my pcu makes some noise and when I push the power cable inside it properly then it stops so it could be a faulty cable too right? Somebody please reply
Will this damage my hardware. I have a cooler master g550m smps
Well, a bad or faulty power supply can damage your hardware, so if you are having problems then its best to replace it with a good power supply.

Hi. I've been having the exact problem for months now. So I thought that it would be a power supply issue. It was not - the power supply is perfect. I still changed my CoolerMaster 850 watt power supply with Seasonic 850 watt gold, still got the problem.
I tested the computer in another house and it runs perfectly with no crashes. So, here's my question: if I get an UPS, will it help me to fix my problem? What do you think?
I live in a 19 sq.m. garage where the power cables are a bit thinner than in ordinary apartements. this MUST be the issue....
Did you managed to fix that problem ? If yes then how ?
@@ezty564 yeah I did. The reason was stupid - GPU overheat. The PC was essambled by a friend of mine. He's very good with PCs but this time he forgot to properly screw one of the bolts of the cooler. As a result, the cooler wasn't touching the GPU as it should. Fixed it myself in no time once I found it.

After so many frustrating hours finally it was SMPS thanks mate.
I tried everything
1. Ram
2. CMOS reset
3. Hard Disk
4.System settings
Another reason I changed SMPS last is that in the multimeter faulty SMPS power was showing 11.99 so I thought maybe it's ok but later in new SPMS the output power is 12.10v.
So, the problem has been sorted? 😊
@@TechGuyCharlie Yes I can probably say that the problem has been fixed because I have been using system for some time now no crashes or restart issue.
The funny thing is in this video you changed from faulty cm mw SMPS to Corsair vs
But for me I changed from faulty vs550 to cm450 😆
Corsair also failed on me 😂 if you have seen my newer videos, I diagnosed a faulty 3 year old rm1000x which is supposed to be one of the best units, surprisingly the power supply in this video still works to this day.
I have a question,
1)when replacing the motherboard, do you need to remove the components on a laptop?
2)Can I upgrade my desktop computer's RAM with a new RAM which is not designed for it? will it still work?
yes
No
Maybe
Depending on the price range, I think you should get repair if it’s under warranty. If it’s an old laptop I think you should Selvage the hard drive, then get a new one.
Great video, i have the same problem with a litle diference, when the pc shuts down some times i see the windows screen, shooting down the pc, and when i test the psu the voltage goes higher than 12, arround 13.40, this could be the problem?, thanks in advance for any help
Mayito Gonzales found a solution I have the problem right now
I'm dealing with this problem. Replaced psu problem still exists. Gpu happened to fail, replace same issue. Did a few updates, and it seemed fine for a while, but now it is back again after a few months, pc it up to date.. Only things left are MB and ram. I was also thing about trying a new surge protector
Might be a long shot, but my PC randomly restarts too, but it could be within a few minutes of being in windows or not at all for hours or the whole day. I'm not doing much on it besides browsing, watching movies and mining when not in use (gpu temp is fine). So for me it doesn't necessarily restart due to high load or anything, but it's completely random. I've already replaced the mainboard and had the same issue. Might look into replacing the CPU just to test.
Could it be the PSU as well? It's actually a decent one (bequiet with 750W).
If you have replaced the motherboard, chances are its the PSU!! I've built countless PCs and never had a defective CPU! its almost always the GPU or the power supply or in rare cases a bad overclock. What PSU do you have right now?
@@TechGuyCharlie Thanks for the response :-) I have a bequiet Straight Power 11 (750W). CPU Ryzen 3900x and GPU is a very new 6800xt. I've read earlier today that at least 650w is recommend so I should be in the green zone. I have done zero overclocking on the cpu, in fact I only placed the motherboard just today, updated BIOS and then set the CPU VCore from Auto to 1.3 (for some reason Auto yields very high voltages on the 3900x...). I always assumed that if the GPU is faulty I'd see graphical errors on the screen and such, but my issue literally is like somebody pressing the Reset button on my PC case for fun to annoy me. Happens completely unrelated to what I'm doing, so it already occured when I'm literally doing nothing but typing a youtube comment like this or being in full idle.
Edit: I doubt it's the RAM, it is running on XMP and memtest86 was fine with zero errors after 2 hours.
@@w3sp Hey man, did you get it sorted? If so was it the PSU? I got the exact same issue you have, it seems to happen randomly once/twice a week, when idle or playing games.
@@w3sp did I literally have the same issue as you I thought it was the PSU so I changed but still nothing. Pleaseeeeee give me an UPDATE.
@@KevinS47 Nope, unfortunately not. I've also reinstalled Windows and also changed stuff around in Windows (e.g. disabling the Automatic Restart on System failure) etc but it's still as if there's a little troll hiding in my room who secretly presses the RESET button on the PC case whenever he's bored. I bought a PSU tester from Amazon and it appeared to be fine, but I'm not sure if those are 100% reliable.
Three days ago I've changed all of the CPU related voltages in BIOS from Auto to Normal. Before I'd either have those set to Auto or Manual (e.g. 1.3, 1.31 or whatever for Vcore). I haven't had a crash yet since I did that but I believe it IS too early to tell whether or not that was the culprit.
