I have a BRAND NEW 13" MacBook Pro. I had Leopard running 100% smoothly, correctly, wonderfully; I installed the Snow Leopard upgrade and it is ALWAYS HOT, SLOW, it freezes up every 5 minutes!!! I have to take notes on this computer for school so I need to it work like it did before. What is wrong with it? My hard drive is BRAND NEW so its not that and don't say it is. Because before SL, L worked fine! I have SMC Fan control running, could that be it? Or this thing called caffeine to keep computer from going to sleep, and the internal stickies application. That's all. Just running something like Safari makes it freeze up. Then I go to force quit it, and finder freezes up. 5 times in the past 30 minutes I've had to force shut down the dang thing, and I'll be lucky if this doesn't freeze up... Oh look at that, I go to click a different open tab in this browser and what does it do? Freezes for 5 minutes. UGH. What is wrong and how come every one seems to have it perfect? I can't afford an external hard drive so I can't back up with time machine so I AM NOT doing a clean install. What can I do? IS it one of those apps running in the background? And the system is always at 74 degrees celcius or more. What is up with that?
