PC Random shutdown issue.
Right, heres the scenario.
I have a fairly small case, but with a fan at the front and back for decent airflow.
I own a GTX 280, which I've set it's fan speed to be 100 percent by the time it gets to 60 degrees celsius.
This GTX 280 requires 40A on the 12V rail of the PSU, my current one provides 38A
Now, my PC works fine on games like San Andreas, but I tried EVE, and GTA IV, and after a while my PC turns off, no error code or anything.
I turned my PC back on, loaded up EVGA Precision, and it read my GPU as 73 degrees celsius. Bear in mind that it must have had time to cool down on load-up etc.
So, what do you think the issue is, heat? Or the power supply?
My GTX 280 came factory OC'd (very little). Would Underclocking it a small amount help, or not really?
