Just bought my macbook about 8 months ago. earlier today, I was on the internet when it started to slow down. It got slower and slower until it completely froze up. I tried different things and before i knew it the screen went black. The curser was spinning, then it also disappeared. I waited for the battery to die and i turned it on and it seems to be working a little slower. I also noticed the light in the front of the mac doesnt work. Can anyone help me out on what is going on?
