What Video card you using, or do you use onboard.
There are many reasons for the big blue screen of death on Windows-based systems, but it sounds like your video card fried. When you rebooted, did you do a cold boot or a warm boot? When I get a BSOD, I always do a cold boot: power down completely and wait at least 30 seconds before powering back on. If you still get no video, it's the card.
