I recently had a problem with my hard drive not working.....while trying to fix that I think I wrecked my computer. My computer now will not boot up.....I disconnected everything and when trying to boot up, it would be constantly. I found out that the memory was wrecked (I think I might have hit it with the hard drive when i tried to move it.) I tried some memory of my roommates, and the beeping stopped. However, it still doesn't boot up. I have tried a different video card and a different power supply. Any suggestions? I have a Abit KT7A motherboard with a AMD Athlon 1 ghz processor with Windows 2000.
