People like to complicate the troubleshooting a dead computer, but it really is easy when you use common sense and not over think the computer problem in front of you.
As a PC Repair tech for over thirty years, I once had a problem where none of the above helped. Not to belabor the solution, an online help response gave me the answer: REPLACE KEYBOARD. It WORKED, unbelievably! Holy Crap!
Good vid Brian :) Back in the mid.late '70's when I started messing around with amplifiers/electronics the rule my dad taught me when you have a 'problem' was - always start with the Power Supply. Over the years it's saved me much time :)
Thanks for the video, but, I have to mention something about substitution testing that you didn't mention. As an ex-military aircraft tech, this is something that I have encountered. There could be a remote fault that is causing, say, a short circuit that is damaging a particular component. So, you swap out the suspect component, power up, and bang, the new component is also damaged by the same fault! That is the one drawback to substitution testing. I felt I ought to mention that.
3:37 You have presented a lot of good information. An alternative for testing the power switch, I would recommend using a screwdriver to jumper the pins on the motherboard. It is usually the set next to the spacer. It is a lot quicker process, and usually finding a screwdriver is much easier than the standalone power cable that has been stored away.
Power Supplies have always been the ones that fail first for me, the other was a fan failing and causing over-heating auto-shut downs or something of the sort.
I fixed a pc a couple months ago that had a bad start button. I just started the pc with a screwdriver on the jumpers. I've got a couple large boxes full of extra parts I can use to swap out for testing.
Some good tips especially when your PC dies and logic goes out of the window when entering panic mode 👍 Your out-tro regarding subscribing etc is very low on volume with your voice not sure if this is intentional to get us to listen more intently? 😁
@britec09 when you run into a black screen instead of seeing the desktop and Ctrl alt delete isn't doing anything and the mouse is the only thing you see that resembles Windows do force shutdown windows (hold the power button until the computer shuts down)?
I had this 10 years ago that the power unit suddenly after 2 weeks burned out, this was with a completely new ready-made system (what can those power units smell) the power unit was some cheap thing and too weak for the system. For me never a ready-made system again, I build it myself know, and I know whats inside.
Brian, my PC came up with a disc error couple of times then a couple of days later it crashed and will not start up. I assume this is a bad hard disk? Also, my motherboard might have died too however, it's still for Windows 8. Should I also get a new motherboard while I'm at it?
Always check to see if the cpu fan is working properly if your computer has any kind of issue. Especially if it's a recurrent issue, because an overheating CPU or GPU is a huge culprit for those. Especially if it has a cooler with some sort of coolant or something. If your fan breaks in the wrong way it can spill the coolant... Which is very bad if it ends up on a cpu or gpu. That's a fried processor. That's bad. If you can't tell, this happened to me. 😭
IT Services Gold Coast Hello, I have this laptop HP Pavilion x360 - 14-dh1038nia, which had an update a while ago thus making the mouse touchpad unusable after Windows boot up. Have tried several methods like drivers update via HP Support,Windows 7,8 & 11, Linux but the device can't be detected by the system. However, on loading up the bios the mouse works fine but as soon as the OS loads it disables, thus being forced to use an external mouse.How can i revert to the default OEM drivers or what could be the issue.
For laptops: try a hard reset with the laptop unplugged (hold power button for 30 seconds) Then unplug the battery, see if it works without the battery. If that doesn't work, remove the ram, drive, fans, heatsink and wifi card, and see if it powers on. If that works, put each piece back where you found it, one by one until you've found the one that prevents it from turning on. If that doesn't fix it, you probably have a bad board.
Anyone else having trouble with humidity? I thought my Motherboard was dead but it was just damp from the humidity. I built an xbox one cased computer for my channel and i nearly thought i lost it.
The problem might be a combination of humidity and dust. The dust absorbs the humidity and short circuits the computer. Carefully vacuuming out the computer might help.
I know who you are talking about, they think the beeps and motherboards LED's don't mean much and think every hardware problem is due to a memory module.
hey ,if anyone else is searching for repair guides try Saankramer Electronic Magazine System (Have a quick look on google cant remember the place now ) ? Ive heard some interesting things about it and my m8 got excellent success with it.
I will think maybe 20-25 years ago PCs could be repaired but not anymore. everything is just replaced. when they brake people just replace them no business in PC repair anymore.

Sounds like a legacy bios problem

It sure does.

Yeah you can do that if you want.
Before you go out and buy a new power supply grab your multimeter and measure to see if the voltage is good. Thanks for the video.
Yes I agree
Excellent, excellent video. Thanks. I wish I saw it 7 years ago and saved time, money and aggravation. Love your videos
Yeah it can be a nightmare when you don't know what to do.
Power Supplies have always been the ones that fail first for me, the other was a fan failing and causing over-heating auto-shut downs or something of the sort.
Yeah bad PSU is the place to start
Nice tips, also with the older power units when they were full of dust the power just did not come on until you used a vacuum cleaner on it lol
As always, the BEST computer repair videos on RUclips. Where can I get the power switch you showed? Now, will you do one on a dead laptop? :-)
Yeah i can do laptop, UK amzn.to/2QdV2AI US amzn.to/33fumok
Im trying to learn how to repair computers and all the other videos are about 60 minutes long, but i luckily found this vid. Thanks a lot
Yes Sir: I had Good Power Just Not enough when i put in a Hungry Graphic's Card...But it did the trick; Game On....Thanks!
You're welcome
Some motherboards are very particular about memory and the slot(s) in which it is installed. Checking the motherboard manual is very important.
Excellent video! Excellent and succinct explanations! :)
Can you provide a list of parts and cables needed for efficient PC troubleshooting?
I see what I can do.
@@Britec09 Ditto on George Wills request!
I can't give you "10" like's !!! Good Video !!!
Thanks
I fixed a pc a couple months ago that had a bad start button. I just started the pc with a screwdriver on the jumpers. I've got a couple large boxes full of extra parts I can use to swap out for testing.
Yeah you can use screwdriver
@@Britec09 I screw with confidence. 🤣
Did the "Kitchen Tech" teach you all this? LoL!
Just kidding... Thanks for the video Brian. 👍
You can't even compare the two, one builds computers and ones a proper tech lol
@@Britec09
Obviously! LoL!
Cheers for the video Brian....Don
You're welcome Don

Your out-tro regarding subscribing etc is very low on volume with your voice not sure if this is intentional to get us to listen more intently? 😁
Thanks, I will look into that.
Thank you for making it so simple.
I know experience when I see it. Great video.
@britec09 when you run into a black screen instead of seeing the desktop and Ctrl alt delete isn't doing anything and the mouse is the only thing you see that resembles Windows do force shutdown windows (hold the power button until the computer shuts down)?
So, we have to buy a complete new setup to replace the components one by one in case of some trouble.It's better to make a new complete build.😋

Thanks
Britec09 your welcome
You can diagnose most computer hardware problems with a DC voltmeter Posted on Facebook, Bye for now Cheers
multimeter is a must have bit of tech
What to use on the keyboard instead of LB and RB switches
Good stuff !
Glad you liked it
can u make a vid on how to install windows 7 on 8th gen intel cpus?
I see what I can do.
Thank u mate, i love this vid man
Thank you great video.
Thanks
4:19 what if you have an all in one ? Mty computer will not come on!
99% of the time it's a dead power supply - especially if you bought a pre-built because they don't come with great PSU's to begin with.
For laptops: try a hard reset with the laptop unplugged (hold power button for 30 seconds)
Then unplug the battery, see if it works without the battery. If that doesn't work, remove the ram, drive, fans, heatsink and wifi card, and see if it powers on.
If that works, put each piece back where you found it, one by one until you've found the one that prevents it from turning on.

I have an issue laptop keeps locking every 30 mins when I watch RUclips I'm on windows 10 any ideas why power options on never and no virus on scan
Will i be able to test my pc with only a bios buzzer ?
You know your stuff
Been doing over 30 years
But even if its a faulty ram stick, the pc will still turn on, but no picture
my m.2 drive is not seen in the bios.
I also had broken USB ports/devices aswell cause that
The only power I have is the orange light on the motherboard.
A bad bios battery makes it not come on
Damn so really have to buy 2 pcs
hey ,if anyone else is searching for
repair guides
try Saankramer Electronic Magazine System (Have a quick look on google cant remember the place now ) ? Ive heard some interesting things about it and my m8 got excellent success with it.
First!
-rchlt 2020 LUCKY!!!
What's going on with the mic sounds like it's recorded in the 80s
Microphone messed up during the recording and did not have the time to redo it.
I will think maybe 20-25 years ago PCs could be repaired but not anymore. everything is just replaced. when they brake people just replace them no business in PC repair anymore.
Thank u mate, i love this vid man
