While listening to music the screen saver displayed random pics. HD crashed. Reboot and mode selection appears.No matter which is chosen it keeps coming back to that screen AFTER it flashes 'the blue screen of death' . Screen flashes to fast to see what problem is listed. F10 - Edit Boot Options comes up in DOS. 'CHKDSK /F' took 6 hrs - no probs found.Still returns to the 'mode' page. Discs included have no effect. I can't prompt the computer.
