I have a cobbled together pc, the top of two cd drawers says " Compac RW 52-32-52" I has started opening and closing on it's own agenda, over and over again. It does not stop with restarting. It does not respond to my pushing the button to operate it manually. It does not stop if I put a cd in it and ask it to play. It keeps opening and closing, over and over. Could this be a hardware problem - or is it likely a virus? thanks for any ideas you can send!
