Just to clarify, the hard drives spin, but don't try to boot, they don't get that far. I don't even think they get past POST, because I get NO beeps. I've tried swapping RAM with some that I know to be good, which by the way, One of the systems worked just fine, until I shutdown, and then it wouldn't reboot. I'm totally stumped. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
