Acer Aspire M5641

OK, it has been a few months and I got a new computer and I went back to
my acer to try and fix it. In Febuary i was listen to music and on the
internet and i came back and it had a black screen. Restarted it and
still a black screen.

I did some research and thought I'd try take out the ram and clean any
dust. Well that worked, kind of. I started it reguarly and got a blue
screen and had to turn it off. Does that every time on regular start up.
If i try repair start up it just loads the windows loading bar and does
that forever.

Today I tried F8 and did return to previous bootable state. It booted,
but with a black screen again. I did just safe mode and it froze during
that boot up, well i dont know if it froze, but its stuck at
windows/system32/drivers/crcdisk.sys

Umm Im at a loss, anyone got an idea?
