For some reason my computer wont let me open the volume options so i can turn up the volume. Right now it is stuck at 12%. Even when i go to the control panel to open it from there it doesn't do anything. At most it makes it look like something is suppose to pop up because when i click on adjust system volume the x to close out will not be red anymore like its a background window. How do i fix this were i can turn up the volume on my computer?
