My computers won't start! :? Suddenly and for no apparent reason, they both are dead (heretofore nice units, freebies from the local middle school). I've pulled the boards, reset them, reseated the ram, checked all the plugs. The little green power light doesn't come on, and the hard disc starts spinning, then stops. Black screen on both too. I'd like to keep one of these running, because the kids enjoy the old school jump start games and triazzle. Any help would be greatly appreciated.
