Wondering if anyone can help me from smashing my MacBook with a big hammer... I bought this new macbook pro 13' a few months back and upgraded to Lion right away and all was good. Yesterday I decided to do a fresh re-install of snow leopard on it as an older machine running SL seemed to run faster than my mac. Since installing the older OS, things do seems to be running faster, but now it overheats when playing flash video. The bottom gets hot and the fan speeds up to an extremely irritating volume. It never did this until now. Now it's acting like a 5 year old plastic macbook. It's really annoying me as one of the main reasons I got the new macbook was to end this problem. I can't think what has changed and caused this since the re-install, lost some graphics drivers or something??. I will try upgrading to Lion again too but can't right now because of massive problems with my apple id, it has been disabled apple. Any ideas?
