Sound Issues

[DrClocks]

So two days ago i came home, I put on my headphones, and when i booted up my PC there was no sound. 

 

I just thought that I must restart it and the volume would be properly working, but when i restarted it did the whole "diagnosing your PC" stuff, and the problem continued.

I looked online, and found one that just told me to go into services and activate it. Now, even though the Icon for the no sound stuff disappeared, the problem still occurred.

 

I tried it out on another machine, and it ran just well.

 

So either my computer just doesn't wanna work, or my sound card don't wanna work.

Help, I really want to play Team Fortress 2 but I cant really do anything without headphones since spies and stuff would easily get me, 

and like any rational human being I like audio in my video games.

Please, bye!

This doesn't work with speakers either.
