Usually your symptoms happen when the machine is underpowered. Sounds like you have enough. I wonder if there is a file corruption lurking. PS is not releasing, or using all the memory it can. There are various ways of trying, I am guessing here though, but none should take a huge amount of time.
The standard remedy is to delete preferences with PS. (see the help file for the correct procedure.)
Check you preferences. Is there sufficient memory allocated to PS? Is there some background program grabbing your memory.
Are your video drivers up to date. there is also the not very likely possibility of a driver conflict,
I would also consider a virus scan using something like ETrust. I have a thing about not using Norton, which has been known to cause strange behavior.
Past that I have run out of ideas.
