computer powers off with no warning then powers on again

June 13, 2013 at 12:13:19
Specs: Windows 7
so i just recently built my rig, here are the specs:
CPU- i7 3770k at 3.5 ghz
GPU- Gigabyte geforce GTX 690
PSU-corsair AX 860
Motherboard- asus sabertooth Z77
RAM- Gskill 2*8 GB at 2400
water cooling on cpu- corsair h100i
and 3 big fans to circulate air.

so everything works perfectly except i have random restarts when doing ordinary things like watching a movie with no warning. its like someone pulled the power cord out then it just restarts without me doing anything. i know its not heat problem because i have sufficient cooling for my system and it is only 2 months old and i have already cleaned it. i checked my drivers and it seems they are ok. i know i dont have a virus either. i have re installed windows 7 and this did not fix the problem. my computer can go for days without the restart and some times for hours only. any help would be appreciated. also i some times get a msg after the restart where my computer checks the C drive for corruption. how can i fix this any help would be appreciated. =)

"3 big fans to circulate air"

A single rear exhaust fan is all that's necessary.

"water cooling on cpu- corsair h100i"

Did you check the CPU temp reading in the BIOS? Why did you feel water cooling was necessary?

Try disabling the auto-restart feature, that way a BSOD will be displayed & you may be able to track down the problem based on the error message.

You don't know the unit is not overheating. Install HWMonitor to monitor the temperatures and voltages in real time.

As riider stated, you only need one large rear discharge fan. I bet you also have a case with a bottom mounted power supply.

I emphasize on what has been said above, and i do find water cooling not necessary unless your planning to do so extreme overclocking

computers are a second home

I checked the temps in real time as suggested and its not a heat problem. sometimes the computer goes for days without a random power off and power restart. i think it might be my power supply? what is causing it to keep powering back on then off again?

Run memtest86+ to determine the issue is not the memory.
