I was told motherboard was bad (opinion did not come from here ... but from Gateway Tech Support) so I put in a new MB in my GT 5082. Replaced because original problem was that the computer froze and though it would power up ... there was no display and reinstalling RAM made no change. Now I still have no display, hard-drive does not power up, and there is a constant, steady, repeating single-beep coming from the rear of the tower. Any ideas? BTW ... monitor is good and hard-drive worked as slave on another computer.
