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.
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? 😁
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?
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.
@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)?
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.
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.
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. 😭
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.
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.
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.
