Hi all, like title says my macbook is beachballing a lot. Even for things like typing, my MB will type half of the word, then beachball then finish the rest. It seems like my MB is working just fine when first turned on, for example I watched two youtube videos just fine. Then it started beachballing so bad I had to restart by pressing down on the power buttom. The ram I bought/installed was Kingston 4GB(2 x 2GB) HyperX Mobile SoDIMM 200-pin DDR2-667/PC2-5300 According to my research it should work, but other than one adult website I went to, I don't have a clue what would be causing this.
