I have a new athlon1.4GHz, 256DDR,NVidea GE2 400, with 98SE ( I got rid of ME - too buggy ) the system will hang with a black screen if left. The screen saver works for a while - then black screen. It then will not wake up if I move the mouse or hit a key . Monitor light still shows a video signal. Have to reset to recover ? ? ? ? ? ?
