I was on my computer. i had a download going. i place a movie into my disk drive, goto my computer to open it. my computer becomes unresponsive. i end task it, this ends windows explorer and therefor i lose my desktop. being impatient, i did a hardboot. and now when loading, windows gets to the the screen with the blue loading bar just fine. but takes much much longer there. then the screen goes black for a couple mins. then it loads. any ideas on how to fix this?
