I figured out why my computer was crashing every time I played GTA2. It was because my CPU was overheating. I guess it's ware and tear because it never use to do it at all.

Anyways, the way I fixed is that I turned it down... it was set to run at full capacity at 166 mHz so I turned it back down to 100 mHz. Although the computer now lacks about 25% of the processing power, I haven't felt it yet. No big deal.
