All in Wonder Up and Quit all of a sudden

Hi,

I have been using my AIW 7500 for about 2 years with no problems. Last night I played a movie in Windows media player and fell asleep. When I woke up. The screen was black. I rebooted and there was still no video output during POST or when windows XP booted up (i know windows boots, because I can hear the startup/shutdown noises). Does anyone have any idea what the problem might be or how to fix it?

Thanks,
Lance
