My PC keeps randomly rebooting

  Adrian Hajdin 15:56 31 May 2017

As stated in the title, my PC is experiencing random reboots of system. The problem started happening few months ago but I didn't bother as much, and since reboots started to get more frequent I bought a new PSU because I thought I might have less power than needed. As I am writing this, reboots are still happening, so new PSU obviously haven't solved anything. Overheating doesen't seem to be a problem, I checked the temps, CPU isn't getting over 60, and GPU isn't getting over 80 degrees.

Reboot is happening mostly when I am playing Overwatch, sometimes after 10,20,30 minutes and sometimes it can take hour or more to reboot. It's also happening while im writing documents in Word and browsing the web simoultaneously.

The steps I already tried to do are: - swapping different GPU - completely reinstalling windows 10 - removed all other usb devices and kept only mouse and keyboard - checked the temp

My configuration:

CPU - AMD - FX-8120 3.1GHz 8-Core Processor GPU - XFX - Radeon HD 7850 2GB Video Card Motherboard - Gigabyte - GA-990XA-UD3 ATX AM3+ Motherboard RAM - Kingston - 8GB (1 x 8GB) DDR3-1333 Memory SSD - Kingston - HyperX Fury 120GB 2.5" Solid State Drive HDD - Western Digital - Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive PSU - MODECOM Volcano 650, ATX v2.31 (650W)

Any help would be higly appriciated!

I checked, and there are critical errors. Source: Kernel-Power, Event ID 41, Task Category (63)

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

What could that possibly be?

Kernel Power can be caused by many things - see here for the microsoft guide to gaining a bit more information provided by the error codes in the event viewer. Let us know what the error codes you are getting are and we can provide more help.

KP 41 tells you exactly what you already know - it shut down unexpectedly.

If your sure its not PSU voltages or Overheat. then start by updating or rolling back your drivers one by one until it stops crashing - do graphics drivers first.

May also be worth running a check on your hard drive. memory test also worth doing but would have expected a different event code if a memory glitch.

Just to clarify is the system rebooting or restarting? Have a look at your motherboard see if anything looks abnormal then you should start running some memtest and mobo diagnostics.
