ok, so ive had my custom pc for about 3 months now (asus k8v se, amd 64 3200, 1 gig crucial ram, 6800 gt, 2 raptor hdd's, etc) and its been working fine up till the last 2 weeks
i have everything overclocked (gt at 440 and 1.20 and cpu at 220mhz FSB)
and with those settings, i was on the threshold to system lock ups, but the machine ran fine, even for days straight
but lately every now and then the computer would freeze up, or id come back and itd be shut off (i have no virus')
so i underclocked everything (gt to 425 and 1.15, cpu to 210 FSB)
but after i ran 3dmark and aquamark, then did a defrag, the computer shut off on its own again, and now it wont turn back on
if i turn off the psu, then turn it on, everything will run for half a second, then die, but the LED on the asus mobo stays lit all the time
any theories??
something shorting out maybe?
