Last night, i was surfing the internet, and my laptop froze. So, after waiting a while, i held down the poewr key and turned it off. When i restarted it, it went about halfway through the boot sequence (didn't make it to the desktop) and froze again.
Now, everytime I go to start it, i hear the fan start, the green light goes on, and then everything shuts down within 5 seconds.
HOWEVER, occasionally (once out of maybe 30 tries), the computer will start and make it to the desktop, but freeze again. sometimes, it'll just make it to the first startup screen, etc. (I've tried starting it in Safe mode when this happens, but the same thing occurs).
One time when i went to power on, i got a blue screen and it did a 3 step process to fix a dirty something. I can't remember exactly what it said.
Does anyone have clues on what I should do? I have so much information on my computer that I need for finals this upcoming week at college!!
