ok so I'm in trouble here. My black macbook (early 2008) has been acting strange lately. It started out with iTunes opening slowely. It took like 5 minutes to load and come up. It ran fine when it finally did come up but once closed down and opened again it still took forever to open! Then Quicktime started doing the same thing. Then today after I downloaded the new iTunes, neither iTunes nor Quicktime would open! They kept crashing. I decided to use VLC player instead and it started crashing too! Then Firefox did it too! I repaired premissions and decided to restart my computer. However it came to the blue loading screen and didn't load any further. So now my operating system is not working either. Can someone help me? My windows partition seems to be working fine (I'm typing on it now). Any suggestions are really helpful! I need help guys, this thing is my life!!!!!!! Thank you so much!
