Hi, Since i use Snow Leopard i get randomly (around 1 to 10 ) freezes. When i get it i can click some applicaties but can't make changes in it. the beachball keeps spinning for some seconds and after the wait i can just continue working. I first thought it was Firefox, because it almost everytime happens when im browsing the web, but i get the same with Safari. It's getting verry annoying now :-( I already checked: - Repair disk - Repair disk permissions - Run Apple diagnostics Repairs my 1.5 year old mbp already had: - 2x keyboard - Topcase - Logicboard - Superdrive Anyone has some suggestions?
