Computer Repair: Quickest Way to Diagnose Dead PC

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.

Some motherboards are very particular about memory and the slot(s) in which it is installed. Checking the motherboard manual is very important.

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. 😭

Thank you for making it so simple.

Thank u mate, i love this vid man

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.

Excellent video! Excellent and succinct explanations! :)

A bad bios battery makes it not come on

The only power I have is the orange light on the motherboard.

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.

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.

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.

But even if its a faulty ram stick, the pc will still turn on, but no picture

I know experience when I see it. Great video.

Will i be able to test my pc with only a bios buzzer ?

Damn so really have to buy 2 pcs

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

Thank u mate, i love this vid man

What to use on the keyboard instead of LB and RB switches

Cheers for the video Brian....Don

Good stuff !

Nice video, very helpful.

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.😋

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 :)

I also had broken USB ports/devices aswell cause that

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.

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.

I can't give you "10" like's !!! Good Video !!!

You know your stuff

can u make a vid on how to install windows 7 on 8th gen intel cpus?

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!

Thank you great video.

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.

Can you provide a list of parts and cables needed for efficient PC troubleshooting?

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.

You can diagnose most computer hardware problems with a DC voltmeter Posted on Facebook, Bye for now Cheers

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.

my m.2 drive is not seen in the bios.

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? 😁

What's going on with the mic sounds like it's recorded in the 80s

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

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.

Excellent, excellent video. Thanks. I wish I saw it 7 years ago and saved time, money and aggravation. Love your videos

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!

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.
