Hi grit_rooster,
•Does this happen only with sound drivers?
Step 1: First try to download the driver to a different location and try installing it.
Step 2: You may also try right clicking on the .exe file for driver and select run as administrator to install the drivers.
Step 3: You may also try to download the drivers on another computer and extract it and check if it works.
Update drivers: recommended links**http://windows.microsoft.com/en-US/windows7/Update-drivers-recommended-links**
Hope this information is helpful.
