Spontaneous reboots - NO BSOD
Have a pretty new ASUS notebook and in the past few days it has started doing spontaneous reboots randomly without a BSOD.
I have 6 Gbytes of RAM and my first thought was that I must be running into some bad memory. Tried running the Win 7 memory diagnostics tool manually, but I can't even tell if it is running. The power light stays on and the screen goes blank. Attempts to hit F1 to bring testing options up does nothing. I left the computer in that state for about 15-16 hours from yesterday afternoon until this morning with no change - power light still on and screen blank. I can hit the power switch when it is in this state and it will shut off. Then it will reboot, sometimes normally or sometimes giving me the B&W screen asking if I want to boot normally or in safe mode, etc.
I'm lost. The computer is a refurb and the warranty only has about 2 weeks remaining.
Update: I got it to boot up and run Memtest86. I'm running that now and will let it cook all night running that.
