Live Crashes Computer

Hi, whenever I load Live 07 and play games, the computer crashes and either get's a blurred screen of the game and everything freezes, or I get a blue screen and it says it's dumping memory, then the computer restarts. This happens every time start a game and play just about 1 minute. I have reinstalled Live and installed the appropriate patches and updated my drivers, but it still doesn't work.

Computer specs:
AMD Athlon 64 X2 Processor 4600+
NVIDIA GeForce 6150SE
320GB Hard Drive
2048 MB DDR2
Windows Vista
