After the computer boots up all menus open quickly - no problems. But after I do some work (check email, open and close some documents, etc), when I go to Start->Programs-> and try to open Accessories, Games, or some other menu, a grey box opens up but there is nothing in there. HDD runs and runs and about 30-60 seconds later, the menu populates. If you try to skip this and go back to the desktop, the system hangs (seemingly until the contents of those menus populate).Seems to me like this is a problem with not enough memory being allocated for use for these menus and they are needing to reload after some other programs have run. Any ideas how to fix this?
