This may not apply but it's worth a shot....

Click Start > Run
Type Regedit in the run box.
Open "HKEY LOCAL MACHINE > SYSTEM > CURRENT CONTROL SET > CONTROL > CLASS >
{4D36E965-E325-11CE-BFC1-08002BE10318}

Look for keys called "Upper Filters" and "Lower Filters" and delete any values inside those keys, then restart the machine.

Note: If using Vista, be sure to right-click Regedit in the program list and choose "Run as Administrator", otherwise it won't let you change the values of the key.


Hope this helps,
