RE: Your computer's apparent demonic possession. Here's a possibility courtesy of the technician at one of my local computer shops. This is for Windows 7. If you're a Mac person or running a different version of Windows, maybe you know how to translate.
Click Start;
Right-click Computer;
Click Manage;
Click Device Manager;
Look through the resulting list of categories for any that are expanded. If any are, one or more of the device drivers in that category will be tagged with a yellow triangle icon indicating trouble.
Right-click each of those drivers and select Uninstall from the menu, ensuring that Delete is NOT checked.
Restart your computer. All drivers should re-install correctly. If they don't, repeat the procedure. If they still don't, try selecting the Update Driver Software menu option.

If all else fails, turn the computer upside down and drop it on it's head like Blamire and Clegg did to Compo to shake the demonic possession out of him.
