[SOLVED] Help: PC restarts randomly

[Bobkwando]

Since yesterday my PC has been restarting by itself at unpredictable times. No blue screen. The link below is a event viewer file showing errors before a restart, I do not know what is causing the problem. I have updated all my drivers but to no avail. I also stress tested my GPU for 15 minutes as crashes mostly occurred when gaming, and it crashed 1/3 of the times so I'm not sure what to make of it. Please kindly advise on possible solutions!

Sounds like it could be an overheating issue if your computer suddenly shuts off without warning.

Try running speccy and watch the thermal temps while under load.

Heat or a dying psu would be my guess. As above monitor the CPU and GPU temperatures. Also please list full pc spec including make and model of psu.

I had a Corsair Hx750w begin to restart the pc on me. Would restart playing games or just browsing, maybe twice a week that happened. Could stress test prime95 or ibt and it would be fine. It was random.

First i tried another set of ram. Still did it. Reboots like that are usually either ram or psu. Replaced psu and haven't had a reboot since, going on 4 months now. Psu was obviously faulting in my case, bad caps probably.

Evga Supernova G2 if you consider.

My canned random reboot Rant
Random reboots are usually caused by the PSU, the RAM or software AND in that order of likely-hood.
PSU - If you can borrow/swap a PSU for testing. sibling/friend you can swap out the PSU and each system will be testing the other.
RAM - run the system with one stick of RAM see if stability returns if not Test all the RAM with memtest 86 for three passes or overnight. if you get no 0 errors after more than three passes the ram is good. with the random reboots I would suggest running this test after the PSU swap or after the PSU has been cleared.
Software - Drivers or other issues can cause reboots. Boot to a linux distro on a USB drive. mint linux will boot to memtest86. you can run the OS from the USB and await reboot.
