I am currently running a mid 2010 macbook pro with the most updated version of lion. Everything with lion has been going great up until I updated to 10.7.1. After surfing the web using safari for a couple of hours or so it starts to freeze up and the rainbow wheel comes up and just keeps spinning. It usually freezes for about 5 minutes then comes back to normal for a few seconds then goes back to the colorful spinning wheel. After this goes on for about 10 or 15 minutes the screen goes black. It then went black for about an hour and after that long I figured it wasn't going to come back so I just shut it down. I would appreciate it if anyone has any ideas on how I may be able to fix this or what is causing my computer to do this.
Thanks for any help!!
