Random system freezes?
Can somebody tell me if I need to do anything special after upgrading the RAM in my PB? I recently added a 1 GB stick from Crucial. OSX sees the memory and everything is running much faster, however I am now getting complete system freezes at least once a day. I will be moving my mouse or typing something and all of a sudden everything just stops. The screen stays displayed but all input is ignored and all programs freeze. The only way I can get out of this is to power cycle the PB. What could cause this?
