I tried restarting my computer to see if installing updates would work. When I logged on, the sign at the bottom of the screen said that voume was on. I tried to play something and no sound. So I went to check the screen again and got this...

I've tried everything you said besides updating the driver and starting in safe mode. Should I try the safe mode now even though the screen's changed?
*Update* I reinstalled the driver and it sort of works. Sound and everything is fine but I can't adjust anything. In other words, I can't adjust the volume level. The screenshot above is still there, I can't touch anything.
*update2* I tweaked around and got the volume control working. I <3 HaTcH :wub: . In thanks, I present to you this
Speed Racer commercial.
