Try system restoring by typing recovery in the control panel search box and select system restore or by using the Windows build in troubleshooter to see the problem.     
Hi all, This morning my computer was running perfectly fine, and then a windows update automatically installed itself and now my whole computer is messed up. I have no sound, two of my games won't work, I can't play spotify, local files or video files. I have tried literally everything. I have reset the drivers, uninstalled them, uninstalled the update, restarted pc a billion times, you get the point. It won't work with headphones or without, please help me. I need this fixed ASAP!!!
Recent windows update has completely messed up my PC.
