Dude, why waste your time trying to fix that POS computer? Everyone knows that the best computer is the Amiga 2000. (The great Doom Master even thinks so!) It's a work horse and never has issues like this!

My A3000T is also not working. I think it has a flakey CPU slot on it. It's just a big hunk of metal right now. Dead as a doornail. I have to open it up every so often and reset the CPU card on it to get it to work. Never have this problem with my Amiga 2000's...
