Hey Guys,
Try right clicking on my computer and going to properties. From here click on the hardware tab at the top, and click on device manager. Is the device manager blank?
If the device manager is blank try running the tool from this website:

This tool requires you to restart your computer in safe mode before running it. To do this press F8 while your computer restarts until you get a screen with a number of options. The first option should be safe mode. Select safe mode and let windows boot up.
After the computer has booted up double click the downloaded file to unzip it. In the folder it creates run the RunThis.bat file and see if that helps. If this fixes the problem please post to let me know.
