My computer just rebooted when I was exiting Halo. I have a 6600GT running on a 305W PSU (6600GT has recommended 350W PSU) and I don't think my temps were too high. I'm just wondering, if this is a power supply problem, why would it crash when exiting Halo and not while I was playing it? Also, the temp of the video card was around 65C when I checked it right before quitting. Any help on this would be appreciated.
