No Sound and flash plays jerk-ish in all browsers.

After trying out Chrome OS in VirtualBox, well, i didn't managed to try it at all, VirtualBox hanged and i did a force shutdown.

As a result, i've seemed to have lost the ability to play any sound from anywhere and flash videos played horribly jerky.

Before:Here


After(first 25 seconds):


When using Camtasia Recorder to record the problem with the video playback this error popup-ed, hope it would provide some lead.


Things i've tried

• Ran command prompt in admin rights to with command "sfc /scannow"
• Ran an error-disk check

P.S. I'm not sure if the comparison above worked since for me both videos are playing really bad.

Also, attempt to restore to prior the installation failed.

If you have a restore point that goes back to a date/time prior to when the problems began you could try restoring your system.
