I should've known better than to try it again - I hate selling old computers to people. I got a new system, and a friend was looking for a server. I put my Gateway Athlon 750 back together and sold it to him. It worked when it left my house (after it inexplicably heated the ram and I had to put different chips in). He said he got it home and it wouldn't work. He dorked around with it and brough it back to me. Tonight I turn it on to see what it's doing and it beeps about 8 times and nothing. No vid signal, you can hear the HD read, and that's it. I'm clueless. Ideas?
