I'm not quite sure what to do. Let me back up a bit, though. I originally got the new computer last December, so I went on a game-buying spree. I picked up some goodies like Jedi Academy, Doom 3, Far Cry, Splinter Cell: Pandora Tomorrow, Knight of the Old Republic, etc. One day while playing Far Cry, the computer just shut down on me. Black screen, and I couldn't do anything. I thought it might be a glich in the game since I had forgotten to get the update patch. I installed the patch, but had the same problem. Soon after I was having the same problem with Splinter Cell and pretty much anything graphic-intensive. However, I was playing the original Tribes at the time when I first got that message above (it came through my speakers). Also, my computer has been significantly louder since the first "blackout" occurred. It sounds like the fan is working over time right from when I start up. It used to be really quiet. Anyways, any thoughts on this? Specs are in my profile.
