|It would help to:|
1. List your computer specs (CPU, RAM, video adapter, other peripherals, etc.)
2. Describe what happens (and what you are doing) when your machine crashes.
3. List the complete version of WindowsXP (SP1, SP2, SP3)
It's less likely that your machine is crashing due to a video-adapter problem than it is for something else to be occurring.
