Stuttering sound + Sound mixer "System Settings" flashing in and out

This is a weird issue I'm having. I did a restart and when I came back BF3 wasnt playing any sounds, which is weird because it was just working.

I went to make sure it wasnt muted in the mixer, and I see the weirdest thing.

The application "System Sound" is disapearing in and out very quickly, not only in the mixer but In devices as well

What can I do to fix it? Maybe reinstall w7 sound drivers?

What soundcard have you got?

What soundcard have you got?

Sorry should have mentioned, I'm using sound from the motherboard, but have noting plugged into it. My headset is a Gamecome 780 which runs via USB

Also when I try doing something such as Properties or disabling on the Sound screen from control panel it crashes saying: Windows Shell Common DL has stopped working

Have you installed anything recently, also have you tried system restore?

Everything has been installed properly, and I had just done a system restore a bit back. Are there some other things I can try before doing a restore?
