Gameplay Beep Noise
Hey, I'm a 16 year old kid that's just now seriously getting into the computer world, and I'm having a problem with something that I assume is a hardware problem.
Basically, whenever I play a game that has any sort of 3D component, my computer will begin to beep at me incessantly after about 20 minutes of straight play time. I can fix the problem temporarily by exiting the game and coming back after a few minutes. However, it will start up again after a little while more of playing the game.
As I said before, it seems to only happen on 3D based games. For example, if I decide I wanna play... let's say the old 1993 Doom game, it won't beep. If I play an upgraded version with better graphics and a much more complex 3D state, such as Skulltag or something, it will now beep at me. If I play a game such as UT, it beeps. If I play a game like some sort of basic flash game off the internet, it won't beep. But like my friend was doing the other day, if I were to wanna play something like that Myspace game Yoville or whatever, it beeps (it's a 3D app or something, I don't know).
The sound seems to be coming from my video card. I can't identify why it does it, though. My computer is three years out of date, but it has never done this before. It only recently started this beeping problem about... three or four weeks ago.
I'm not sure what information I need to divulge to make it easier to answer this question, so if I should be telling something else, please advise.
