I lost all sound on my computer. I have tried uninstalling and reinstalling the drivers,
Updating the drivers. I also have tried restoring my computer back to an earlier date.
Even though there are Restore Points set up, it won't let me restore it back to any dates
At all (I was able to do this a couple weeks ago, but not now). Please help. Thanks so much.

I know you probably are going to say yes but I have to ask haha.

Are you sure the speakers are working properly?
Plug them into something else.

Make sure you check the advanced tab of your Master Volume panel for any boxes labeled mute!
