I've come here in a gasp for help, since i'm utterly scared of what may be happening to my computer. Enough talk, I'll talk you through the facts:
Built computer, stable for over 2 years (specs at the end). Today, having arrived home tired, i went to play a few rounds in call of duty mw3. I do just that, playing with no problems for what i think was about 2 hours of gameplay (had firefox, mumble, mw3 opened). Then out of the blue, my monitor displays "no signal", as if the vga cord was unplugged, i stopped hearing all sound, and the computer continued running. So all the fans are working properly, the correct LED's are flashing, the temperature is no where near critical (the gfx card was the hottest at under 55C). No beeps, no warning signs, no logs, nothing at all.
I am then forced to halt the computer by holding the power button. It does not work. Reset button neither. I can't do a thing at this point, except turn off the power supply. I do that, click the power button to release residual current. Turn on the power supply again, and turn on the computer. The computer turns on, no display, no sounds. I unplug it again. Open the case, reseat the RAM sticks, gfx card, unplug all except 1 hard disk, unplug all non esential peripherals. Turn on the pc, it works. I boot to windows normally, navigate to the event viewer, check the ID of a critical log i find, and it's EVENTID41 (guess it's standard and doesn't say much). At that time, the same crash happens. From then i cleaned some dust off the gfx card's contacts. Proceed to boot, and now the same crash happens while im in the BIOS, in the windows 7 boot logo, and in POST.
I'm clueless as to what could be causing this. I highly appreciate any help i can get guys.
Dual booting Windows 7 ultimate x64 and x86.
geforce xfx 8800gt
amd phenom II x3 720 BE
12 gb of ddr3 ram, 2x2gb + 2x4gb (all gskill)
2 hard disks (IDE & SATAII)
Keep in mind that this has been a stable build for a couple of years. Nothing is overclocked neither has been in the past.
The ONLY change i made to the system in the last days was install the 295.83 nvidia driver
, and a couple of msEXCEL addons.
I'll be checking the thread regularly to supply with any information you guys may ask.
Sorry for the large post.
PS: Typing from a laptop.
EDIT: It seems that the longer the pc stays off, the longer it prevails before crashing.
