Freezing and slow boot up
Hello I have a late 2008 13"aluminum Macbook which was running very hot. I decided to download SMCfancontrol to increase the fan speed and I also upgraded the ram. The heat problem is corrected but my computer freezes up very often. Here are more specs, 2 GhZ intel core 2 duo running OS X 10.8.4 I have 8 gig of ram 1067 MHZ DDR3. I hope someone can help me because I can't afford a new one and I need this computer. It seems to work fine sometimes for even a hour or two but usually it will freeze within a 20 minute period of time. I eventually keep my finger on the power button to shut it off then wait 3 minutes to start it up. Any help would greatly be appreciated.
