Something has corrupted an existing audio driver. This can often result as the result of installing something that does not install correctly.
Did you recently try installing a new driver? or new media software? Either of which was related to audio and/or video? such as a new media player, or sound enhancement software, etc?
Try method 1. If unsuccessful, follow the System Restore instructions to check:
- How many restore points you currently have saved
- How far back in the calendar do the restore points go?
- Select and attempt a System Restore point to a date you think was OK
Method 1. Try uninstalling whatever program(s) install might have caused the problem.
(the problem would have started sometime after the installation)
- click and open
Control Panel->Add/Remove Programs
- Review the list of installed programs
- Anything you see that you recently installed? Try uninstalling and rebooting to see if problem clears up
Method 2. System Restore
Here;s
a Microsoft link describing how to do a system restore to a prior date when things were working. NOTE
- System restore points are NOT complete system backups but only attempts to save system critical data.
- As a result, System restore is not guaranteed to work (because it only tries restoring system data. It doesn't restore all your system and file info and data)
Post back if you have any question. And certainly as to your results as well (i hope successful results!)
