Changes made on drop down list wont stay permanent

[gloriahill]

Hello,
I'm having a problem when I try to make changes, computer will not let me save or apply the changes.

Ex-I try to change the volume and bounces back to the same position it was in as soon as I move the mouse.

I try to use any drop down list and and whatever I click on it does not stay

Does it only happen with windows setting, like the volume or in programs also? And is it the only problem or are there other things beside it?
