Since last month, my PC started having random reboots and giving 'Machine Check Exception' error, similar to these:

And now from the last 3 days the system doesn't boot. When I power on the computer, all fans start spinning but keyboard and mouse LEDs don't light up. Pressing CTRL+ALT+DEL doesn't reboot system neither does pressing the power button for few seconds.
I suspect that motherboard has gone kaput and isn't completing or even starting the boot process, which is why keyboard and mouse aren't getting any signal or power from motherboard or why restart or power down functionality is working.
Before the system stopped booting, I was trying to solve the machine check exception error by updating BIOS, updating chipset drivers, changing BIOS settings etc. But now I'm thinking none of it could've helped because the board itself was deteriorating.
Also during that time, I would randomly get display glitches (pic below) which could only be solved by restarting the machine so I was suspecting it might be GPU that was causing the problems.
Sometimes it would show chessboard like pattern. I guess this was also because of some issue with mobo-GPU connection?
Anyway before changing the board is there anything else I can try? Changing it is a pain so I'm trying to avoid that. 😂
You're viewing a single thread.
Remove the video card, use inboard video, and use a single stick of ram. If it’s still wonky try a different power supply.
There's no onboard video for this setup.
A second idea if you cannot source another gpu; Change PCIe slots. While I believe your video card is going bad or at a minimum: overheating: consider moving it to the other x16 slot on your mobo as it IS technically possible the slot is having issues. It also doesn't hurt to spray your case out with canned air to get the heat capturing dust out.
I tried without GPU and the problem persists. I'll probably take the whole cabinet to my friend's place when he's available and try replacing components one by one.
Definitely have to do it one by one. Process of elimination!
I've had times where I've pulled the motherboard from the case, laid it on a rubber cloth and hooked everything up one at a time to find the issue. Even had one time where the mobo was shorting out on a case itself. So yeah, it doesn't hurt to do that. Good luck!
