Ram Upgrade not working in "mid 2009 Macbook Pro"
I have a mid 2009 13" Macbook Pro 2.26 GHz with 2x 1gb of 1066 DDR3 ram. I installed it into my computer and for the first 20minutes everything was running a lot faster but then the computer locked up and told me I had to restart and now it will turn on start up and work for about a minute before it does the same thing.
The ram I upgraded with is mushkin enhanced 4gb (2x2GB) PC3-8500 SODIMM timing 7-7-7-20
Please any help would be greatly appreciated!!
Thank You
MacBook Pro (13-inch Mid 2009), Mac OS X (10.6.8)
