My computer is sick

Mike came over Monday and helped me (well -- I watched while he worked) install some new hardware in my computer. New USB external sound card device thingy, new video card, new cd burner.

When I came home from work that night, my computer wouldn't work.

Mike spent several hours Tuesday trying to fix the problem, but when I got home tonight, very little works and it still freezes up on a regular basis.

So basically I can't manage to do anything, and I'll be lucky if I get this posted.

Bleah.
