Computer turns itself to mute

[Agnes B]

From time to time, for no apparent reason, my computer turns itself to mute.
I go to Control Panel/Sounds and uncheck the mute box and all is well. But
what makes it happen and how can I make it stop? Thanks.

In normal running mode, accidently hitting F8 Key, mutes the System.

Could be many things. Does your keyboard have a mute button? Could be
malware. You may have to go through the process of elimination to find the
cause. I.E. Prevent one program at a time from loading until problem no
longer occurs. How often does it happen?

Thanks. It's very intermittent with no discernible pattern. Someone else
tells me that hitting F8 mutes the system and since I have a wireless
keyboard that gets picked up and moved around a lot, i suspect it's as simple
as that.

Hm. Thanks. I tried hitting F8 and it doesn't mute the system so I don't
think that can be it.
