GTA San Andreas

I´ve played the game til the end with no prob.
(AMD64 3.0, 1G RAM, XFX 6600 GT)
But a friend of mine just can't play. When he start's the game it boots the computer. (P4 3.0, 512 DDR, ATI 9550(i think))
Anyone?

 

what was it.
it reboots the computer???

 

Yup. I´ve talk with i'm yesterday, he starts the game when he grabs the bike or a little bit after... reboot.
I'll try to install one other San Andrea. Maybe it´s a copy.

 

it may just be that his computers over heating

 

I dont´t think that´s overheating. The Pc has 2 weeks(new). We made a test on him: 11 hours straight of N4SU2. Only then the game shuts down. And BF2 rules well on it!
