Device Manager Blank

I tried to update my graphics driver yesterday and it failed. So I figured I would do it manually through device manager and it was blank. So like many people I turned to the internet. I tried these steps which by the way did not work:

1. Go to "Start", "Run", and enter "regedit"
2. Maximize the "HKEY_LOCAL_MACHINE" window.
3. Scroll down to "SYSTEM\CurrentControlSet\Enum"
4. With "Enum" selected click the "Security", "Permissions" menu.

There were three groups which had these permissions:

Everyone (Read)

Owner rights (Special Permissions)

System (Full Control) (Read)

Click Start, click Run, type services.msc, and then click OK.
    Double-click Plug and Play.

    If you receive a Configuration Manager message, click OK.
    In the Startup Type list, click Automatic, and then click OK.
    Close Services.
    Restart the computer.
