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. 😂
