Volume control?

I have a logitech keyboard and when I use a function button on the bottom of the screen in green the name of that button appears. I'm on the internet this morning and my volume turns down on its own. I click the speaker icon in the bottom right to turn it back up but it keeps going down. My screen has the message'Master Volume' now.

Anyone know whats going on here?

 

What version of windows are you using?
I don't know what's going on but if your using 2000 or xp you might try system restore that might help.

 

Sry, dont want to intervene, but you said when you press the function button, it shows the name of it on your screen. Well if master volume is on your screen, maybe the reduce volume key is jammed in your keyboard. Note i'm not a specialist on these forums or anything, just an insight. Hope it helps in anyway..

 

I'm am using Windows ME.

 

I don't have a function button for the volume control. Sorry I wasn't clear enough.
