Okay this is far from the first problem on my blackbook (the worst mac i've ever owned and I have had 6) but it is by far the most annoying. OSX seems to lock up and totally crash. One program (say Safari or firefox) will freeze and I will begin to get the spinning ball. Within 10-15 seconds the finder and all other programs are totally frozen and the keyboard is totally unresponsive. This happens once ever 5-20 minutes. Any ideas for help? Also I did do a search on mac rumors for similar threads but before I could find anything it froze again.
