I have an older machine running XP sp3. It hangs every once in a while but is becoming more frequent. While working on the computer, or more accurately mostly while surfing the internet the screen will freeze, I'll hear an audible beep from the computer and my screen goes black and nothing but a hard reboot is possible. As a matter of fact it just did it to me while writing this. The event viewer has zero information about the event. I initially thought that it might be my display but I dont think so because for a second or two before the screen goes blank the cursor id non responsive then whamo the screen goes blank. Not sure how to proceed. Help!
