I've got an Athlon 900mHz system running Windows ME, and for some reason it's begun to lock-up while booting up. It's not consistent - sometimes it will freeze right after the video card has been recognized, other times it will get past the drive identification part. When it freezes, both lights on my CD-Rom drive light up, the monitor blinks off, and I have no keyboard controls, and I can't manually restart the system by hitting the reset button (I have to flip the switch in the rear to kill the power supply). Can anyone help???
