Hi there. I'm new here. I was hoping someone could help me. I have a Macbook Pro, details are: Lion 10.7.2, 2 Ghz Intel Core i7, 4 Gb 1333 Mhz DDR3 etc. I'm also using boot camp to run 64bit windows 7 on a partitioned 500GB (250/250) Hard drive. I have next to no documents or files on my mac, but while i'm typing i get little freezes or pauses and the "rainbow pinwheel thing" appears for 2-3 seconds and anything i've typed doesn't appear, but then when the pinwheel goes back to being a mouse pointer, the text i've typed catches up with itself. Its just plain annoying and seems to happen all too often. Even whilst writing this. Another thing is while it freezes/pauses for those few seconds, my music on iTunes stops while its in that state, then starts playing again when it catches up with itself... I'm a bit rubbish at explaining it, i hope you get a rough idea. Any tips would be great, i'm stumped.... Normally i would of thought it was a lack or memory/slow disk or something, but i can't see any reasoning for it. I look forwards to your replies.
