Whenever I turn on my Dell laptop, it goes through the Dell, Microsoft...Etc. and it always shows a black screen and a little white dash in the upper left hand corner. If it ever does start to load, it always stops at 962 of sixty-seven thousand, five hundred and something and it starts flickering and stays there and does not move. I tried doing the Thing where the computer tries to fix the problem, but when it's done, it always tells me to turn off the computer and turn it on again and it always does the 962 thing. Can you help me? I really need it to work. I think it is Windows 7. It has not turned on in a while.
