My System Specs

Default Random Reboot

Hey all:

My computer has been perfectly stable for a few weeks now (since my last hardware/system changes). However yesterday I got a random reboot while idling in desktop (I wasn't there at the time). Today I got another one while watching a movie, and it's quite strange. There was no error message, no blue screen, just instant power off and reboot, similar to when you hit the reset button.

Specs:
Intel Core i7 920 D0 @ 3.67Ghz (37C idle, 75C max Prime95; stock VCore; Coler Master V8 + AS5)
Gigabyte EX58-UD5 (BCLK @ 175Mhz)
G.SKILL 3x2GB DDR3 1333Mhz @ 1400Mhz
ASUS GTX 470 (driving dual 24" 1080p monitors)
ASUS Xonar Essence ST
Corsair AX 750 (750W 80Plus Gold certified)
Windows 7 Professional 64-Bit

I know, I know, first thing to question when these problems occur is the overclock. But because there were no error messages or BSODs, and I tested my overclock pretty extensively (12 hours of Prime95 blend and 50 pass of IntelBurnTest), I think it may not be caused by the overclock. All my temps are fine, and the system has been stable in this state for a few weeks without any problems. Obviously if it happens again I'll lose the overclock and see, but I'm just curious as to what else these random error-less reboots could be caused by.

Just a side note, I haven't re-installed Windows for quite a while (half a year), and I've gone from an ATI 4850 to a 5850 to a GTX 470 in that period (I used Driver Sweeper when switching to nVidia). Don't know if it could be caused by that?

Any tips are appreciated, thanks in advance!
