Out of nowhere the startmenu, hovering over objects on the taskbar, right clicking desktop to menu, using task manager: all of these are now very slow. The thing is periodically it will run fine even though I have the same number of applications running and haven't really changed anything. Everything else runs fast, it's just the windows interface that is slow. I am on an Asus UL80Vt notebook. Thanks for anyone who can help. I am new to windows 7.
