Last night I was calmly typing an essay for homework when my other computer froze. I restared it and as words scrolled on my screen I saw that my computer could not detect the primary boot drive. I restared again and this time it did and showed the windows ME start up graphic but then it said that it could not locate the registry. I have a bad feeling that a virus caused this. Anyone have this happen to them? Anything else that could have caused this?
