The crashes are always different. Sometimes the screen goes completely black, sometimes it flickers badly, and other times everything just freezes. I always lose contact with the computer when a crash occurs and the little colored lamps on my mouse and keyboard are turned off. Also, if I restart the computer with the power switch, the screen freezes either a) right before the boot screen appears, b) when the Windows Loading screen shows up, often resulting in a mass of blue dots on next to the progress bar, or c) five minutes after I enter Windows.
The only thing that helps is rest, apparently. If I don't touch the computer for half-an-hour, I can work with it for approx. 15 min. If I don't touch it overnight, I can work with it for two or three hours.
*sigh* Help?
