Please help
I recently built a new machine with A8n- SLI deluxe, 1G Corsair XMS, Saphire X700, WD 250G SATA, Ultra X-connest 400W PS. Here is the problem, a few times in the last week the machine would suddenly shut down withour warning and I thought that I may have accidentally hit the reset button although it did not resart. I would have to push the power button for it to come back on. The PS is a 20 pin but I am told that the Asus is b.c. any help would be greatly appreciated.
