start menu, accessories,system tools, disc cleanup: hit ok, this will take a few minutes to do. choose temporary internet files, recycle bin, temporary files, compress old files. this will help with some of the issues you are having. start menu, accessories, system tools, disk defragment: select C drive, hit defragment. Don't do the defrag and cleanup at the same time. As for moving files from your © drive to the (F) drive you can right click on the folder of stuff you want to move there and hit "send to" and then select the (F) drive.
hopefully that helps rob
