When I boot into windows 7 it is as usual. You get icons, destkop, start menu, and all that stuff. When I try to open absolutely anything, The Start Menu, A folder on the desktop, task manager, an icon on the desktop, open the windows clock, absolutely anything windows screams at me and says that the application doesn't exist. I boot into VISTA to check if all the files are still where they are supposed to be and they are. I have no idea why the computer is doing this. The only way i can shut down my computer is to hold the power button until it turns off. Any Ideas???
