As the next step, I suggest performing the system troubleshooting procedures per this link and when doing so, follow all steps/instructions in the order provided.
Well i completed all that. No disk errors. Repaired permissions and deep cleaned cache. I used Tiger Cache cleaner and then booted into Single user mode and used applejack auto mode to run all maintenance scripts.
Sadly, Finder crashes still fairly occasionally when i do things like "move to trash"
Will apple care help me out on this if i call them?
Its really annoying.
