I have a MBP 13in bought in September 2010, running OS X Version 10.6.8. It has 2.4 Ghz Intel Core 2 Duo Processor and 4GB Memory with 250 GB Hard Drive. My MBP randomly freezes and it is predictable in the it will freeze almost every time I put it to sleep and then open the lid 5-10 minutes later. After the lid is opened, it will completely freeze after about 3 seconds. When I say freeze I mean that the clock stops, the mouse freezes, no response to keyboard shortcuts or anything. All I can do is a hard shutdown holding down the power button. I have completely erased my hard drive and reinstalled Snow Leopard with no success. I have verified and repaired permissions and still the same thing happens. I have also reset my PRAM with no success either. I am out of ideas and can't seem to find anything to help me out after spending several hours googling and trying all of the above. Any help would be greatly appreciated!!
