I'm not sure if this belongs here or in gaming or Microsoft or whatever. My problem is that I can run Mozilla or any other program fine. But when I play games it locks up (unable to do anything i.e. no Ctrl+Alt+Del or mouse response). I look in Computer Management under Event Viewer | Application and see no errors or warnings. I've also checked under Event Viewer | System and I have no errors. How do I begin to diagnose what's going on?
