I had originally posted this in the Video Card section but now believe this to be a power supply(Antec 480 NEOPOWER) problem.
My computer shuts down after about 20 minutes of use, no matter weather its games (we thought it was over heating when playing games, but it did it earlier, while not playing games) our not, I thought the Video Card was the culprit, but i never got any graphical anomalies, it just shuts down.
We were waiting about 30-45 minutes to restart it (it does not restart it self), if we don't wait the switch on the computer case does not work, but just a minute ago, i reached around to the switch on the power supply flicked it off and on and the computer case power switch worked.
Could the power supply be overheating? It only has one fan that intakes the air from the case, there is no exhaust fan on this power supply.
I have used this power supply for about 1 1/2 years now with no problems. My specs are: 3.2 intel P4, 3 Harddrives, Sapphire x800XT, DVD burner, and 1 1/2 gigs memory.
