When it shuts down does it just restart or is it actually turned off? If it is actually turned off, its probably the board thats needs replacing since you have troubleshooted everything else. And those evga nforce boards have got the worse power regulation, and poor components. Otherwise if its restarts it may be settings that cmos is not reseting correctly. This could be reason for different times of shutdown.
The computer justs turns off as if someone had pulled the plug out of the back.
The XFX tech guy asked if both fans were working on the MOBO, and they are.
However, the mobo has an idle temp of 45 to 47 degrees celsius. Under heavy load it goes up to 65 degrees celsius.
Case ventilation is good with 4 fans on the case.
Could this be the cause?
How can I cool the board more?
