If I just open a game in my computer it hangs!

Do you guys have the solution?

Can you say something more about the problem? Like what happens. Does the computer hang only or it restarts? If it restarts then there's problem of Memory, you may need to extend your memory. Or try changing the RAM slot. Besides, Viruses(trojan specifically) also coz such problems. Try scanning your computer. Does your computer hang only when the game is played? If yes, then your computer might not support it. Try increasing virtual memory if nothing works. Good luck! And be more specific while posting such stuffs then only can someone tell you about your problems.
