Does the volume change when you right click the sound icon in the task bar and use that to adjust the volume?
Do you use speakers?
Have you checked to make sure the speakers are plugged tightly into the speaker port? Are they turned on? Power cord (if your speakers have one)plugged all the way into the outlet? Do your speakers have a volume control? If so is it turned up? Do you have another set of speakers you can try?
I'm asking the basic questions because I have had people complain about no sound and it turned out the problem was related to one of the above.
If checking the things I mentioned don't work it's possible that your sound device has died since you said you used 2 different keyboards and neither worked to control the volume. It's also possible that your speakers have come to the end of their useful life.
If you haven't checked Sound properties do so.
Start menu/Control Panel/Sounds and Audio Devices/Volume tab.
Under Device volume
. Make sure nothing is muted. If it is unmute.
edit to add: My Microsoft multimedia keyboard does not say "Increasing Volume" or "Decreasing Volume" when I use it. I get a small graphic in the lower right corner that shows the progress with a green bar. I was hoping it would say increasing or decreasing so I could see if it disappeared after a second or two.
