Recently performed clean install of 10.7, crashes often
Hello everyone. I recently did a clean install of OS X Lion 10.7 on my Intel Core 2 Duo Macbook (13" Late 2006 model). Since then I have experiencing significant instability with the OS. It has crashed several times now, and crashes every time I try to update the OS software or use Time Machine. Also, the fan is running at a high speed at all times.
I've read that there is some preliminary stuff the OS has to do once installed that may take a while. Could this be the source of this instability? I'm confident that updating the OS would be beneficial, but it crashes every time I try to do so. Any suggestions?
Edit: I feel it is necessary to mention that I went directly from 10.4 to 10.7 on this install.
Thanks.
