He packed up his computer when he left college, and it has worked fine up until about a week ago. Now whenever I start it up from a complete shutdown (power off and everything) and it sounds like it's running and everything, the screen comes on, but all it is is black, I never see the boot-up? screen or log-in or anything. It's just black with two small dots of white at the top left of the screen. It starts in safe mode, but I'd like to be able to get it back to normal if I could.
