Windows t freezes on games

[Guest]

Hello,

I have three computers but the newest one with Windows 7 64bit edition freezes on any game I've had my nephew try. They freeze right in the middle of the games. The only way to stop this is to reboot the computer then it works fine again; until you try to play a game again.
