Right, so this morning, I was using my computer, and it was working the same as always, but then it crashed and I was forced to use a hard shut down. I expected to have to start in in safe mode, but when I tried this, it would load some files, but then freeze, with it making a clicking noise every few seconds. I used a hard shut down again, and when it tried starting up it said it needed a disk check, then got to 9% before freezing and making the same noise. After another hard shut down, I tried skipping the disk check and starting in safe mode, and I tried just starting it normally. It seemed to be working, but after putting my password in it just froze on the welcome screen. It's on vista, and is about 4 or 5 years old. Is there anything anyone can recommend to fix it?
