Have you just installed anything like a digital camera?

Try this if you feel comfortable editing the registry.

1. Go to Run, then type regedit then press return
2. Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
3. On the Edit menu, click Delete, and then click OK.
4. Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5. On the Edit menu, click Delete, and then click OK.
6. Quit Registry Editor.
7. Restart your computer.

NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software.
