Computer randomly turns off

May 3, 2015 at 03:29:25
Specs: Windows 7
I've recently built my first pc. The build went fine and the load of the software went fine too. However when I tried to upload the drivers for the gpu, the pc turned off twice. On the third attempt it finally uploaded the drivers. After that it would turn off when I'd play counter strike. I was able to turn it straight back on. I discovered that I stupidly left the plastic cover on the cooler master heat sink. I took that off yesterday morning and the computer was fine for the rest of the day and let me play whatever games I wanted. I'm only worried because today the computer turned itself off while I was downloading a game. Like always I was able to turn it straight back on and I checked the cpu temperature and it was steady at 35C.

The specs are:

AMD FX8350 Black Edition
Sapphire R9 290 TRI-X OC Edition (OC turned off)
2x8GB Corsair vengeance DDR3 1600Mhz
Corsair graphite series 730T Case
Asus Sabertooth 990FX R2.0
Corsair AX860w psu
Cooler Master Neptol 280L water cooling
Windows 7

Being that it's your 1st build, I have a few questions?

- did you do a bench test before installing the hardware in the case?
- after discovering the error with the plastic cover on the water block, did you properly apply thermal paste?
- did you run memtest86 before installing the OS to confirm the RAM is error-free?
- did you manually configure the BIOS settings rather than just loading defaults?
- after installing Windows 7 (which I assume is 64-bit?) was the very 1st driver you installed the chipset driver?

Did you disable Windows auto-restart feature? Doing so will allow a BSOD to be displayed & the STOP code/error message should be helpful in troubleshooting the shutdown problem.

I thought it was all too easy.
I did do a bench test before installing the hardware.
I had put thermal paste on before realising my mistake. And after realising it, I removed all paste and reapplied a "rice" sized amount.
I didn't perform any tests before I stalling the OP.
I havnt touched the BIOS settings due to limited knowledge (as you can tell)
And the very first driver I installed was the motherboards one, followed by the GPU's one.
How'd I do?

How would I go about disabling the auto restart feature?
