So, several months ago I built up a new gaming rig -- Core i7 920, GTX 285, ASUS P6T6 Workstation Motherboard, Corsair 750W Power supply, and 6 GB DDR3 ram. It is also watercooled with dual loops.
Within the past week or two, it will (seemingly) randomly turn off, no warning, just off. Several seconds later it will turn back on -- sometimes. Sometimes it will try to turn back on and it will just flicker the power several times until it turns on, but does not boot and has my CPU-DIAG led light on and blinking.
I have a couple of ideas as to the problem, but could use some feedback.
1) Power supply is dieing
2) Motherboard is bad
3) Ram is bad (just ran Memtest86+, no errors, but it did shut off during it...)
4) My two pumps (18W*2) are running off fan headers on the motherboard, maybe they are stressing it?
5) CPU is dieing (not overclocked, completely stock setup except watercooled)
I really appreciate any advice or ideas that you have. This is a pretty depressing problem with my new baby...
