the hard drive has plenty of space, I think its the ram memory that's affected. some memory heavy programmes like google earth simply will not work properly, I cant get street view at all. there are things like iexplore.exe multiple ones of that, taskhost.exe loads of those, but in task manager, processes show anything between 1% and 50%, physical memory shows usually around 40 to 50%. not sure how to get the stuff in I-tunes onto an external hard drive, I find I-tunes very confusing and difficult to manage. i restored back to factory setting before, obviously i-tunes went, and when i re-downloaded it, all the music was gone
