So, my mobo is shot and most likely my vid card as well. I've done some research and here are the parts I think I'll get to replace what I currently have.
Mobo: A8N-E
CPU: Socket 939 Athlon 3000
Video: Radeon X800 256MB (does 128MB even exist?)
Now the only thing that worries me is that the computer repair guy who pronounced my current system dead thinks the cause of death
might be the power supply. I don't know much about PSUs since my case came with one already installed so advice on that is welcome.

EDIT: *returns from checking Froogle for 5 seconds*
Geez, power supplies are cheap. I'm not so worried anymore.
son of EDIT: I have an Antec 380W Truepower PSU btw.
