I'm at my wit's end trying to narrow down the problem(s) with my PC.
Specs:
i5 2500k (usually overclocked, but stock for all this testing)
ASUS p8p67 Deluxe
4x4GB Corsair Vengeance LP
2x GTX 460s in SLI (overclocked in windows)
Crucial C300 128GB
Seagate 1.5TB
AX1200 PSU
Long story short, my displays go blank randomly. (as if it were sleeping)
I thought it was memory, ran memtest 1 stick at a time. I found one stick that failed all over slots. But the other 3 sticks seem to go bad randomly (i.e stick two passed slot one 8 passes, failed in slot 2, would cause video card to not boot in slot 3) Stick 3 in slot one had the monitors go black during testing the first time, and passed 13 passes the second time i tried. etc etc.
I would almost say this points to a bad motherboard to have sticks pass in one slot, fail in another, and have another stick fail in that first slot and pass in the second.
When I tried to test my ram in slot 3, it would cause my primary gtx460 not to turn on with the VGA LED lit on my motherboard. It can't be my graphics card overclock because that same thing happens before the computer makes it to windows. But could the faulty ram/board be causing the card not to turn on? sometimes all the lEDS on the card will flash for a second and all go out. If these cards are in SLI, if one card goes bad, shouldn't I still see the other monitor if each monitor is plugged into a different card?
i don't really have the ability to try the shotgun approach of replacing everything so I want to narrow it down from the motherboard, ram, gpu, cpu, and psu before I replace something.
If anybody can be of further assistance and help me narrow it down, that would be much appreciated.
EDIT: this issue mostly happens overnight when idle (or in the middle of memtest)
