I am currently running Windows XP with Boot Camp on my MacBook Air, because I have to have Windows for my school software. Lately, however, when I'm in the middle of doing schoolwork, I get this blue screen on the upper left side of my computer. It basically tells me to shut it down and restart my computer. When I do so, it has to run this "disk check" which takes forever, and regardless of it saying that you can press any key to skip it, it never works. I don't know why this is happening, or if there is anything I can do to fix it. Please help!
