That's the problem, I can't figure out any detail to tell. Basically any program I open it will crash after certain time. It even come to an extend when I'm playing warcraft 3, my game minimized but there's no way I can tab back in because it disappear from application task but the sound is still running. Whenever I open my winamp, it crashes instantly but I'm able to use it after moving the crash report away. There's also MSN problem where I can't send out messages, so I used alternative messenger; trillian, but guess what, it crashes too after a few message.
The only program that hasn't been crashing so far is Rise of Nation offline. I've been playing it for hours and nothing happen.
