Hello. The problem I am experiencing today is in the system tray, when I try clicking on the sound icon that looks like a speaker it will no longer open. But when it was opening I would push the slider up to raise the sound but it would fall all the way back to the bottom. I have attemped to go to Control Panel and when I click on "Adjust System Volume" I don't get any window coming up. I am running Windows Vista Home Premium 32-bit. If I can provide any additional information to better assist me, please let me know. Thanks!
