I recently got a blue screen, rebooted, and no output. I get a screen while windows is booting, but after it goes to load, no image/source. I have speakers and it loads just fine, intro music, and when i plug in a new device i get the little noise...so windows is running just fine...but i have no output from my video card. This happened to me last week, I reformatted windows and it worked fine, but i dont want to have to reformat every week...
