Ok, so I have a consistant problem as of late. Whenever I boot my computer, either from a full shutdown or from hibernation, it can't find the hard drive on the first try. First try it looks, can't find it and goes to a glowing black screen. Second try it looks, can't find it and shoots me to BIOS. I hit F10, enter and then it looks again. Third try, it looks and boots like normal. Perfect consistancy. I've never opened it up and don't recall installing anything or dropping it or anything else that might possibly affect it. Any idea what could be wrong or what I can do about it?
