A hardware failure or an electrical problem.
I have seen this issue on several tv set's where it is related to an electrical issue. The essayist solution is to install a AVR which will ensure constant correct voltage and frequency. An AVR should last years and will protect anything you have plugged into it. This is a good investment even if your issues ends up not being related.
I often have people ask why this problem would start all of a sudden, it is because of changes in you electrical grid in the neighborhood and some electronics are more sensitive then others.
here is a cheap reliable avr unit

How do I get rid of volume bat from popping up in the middle of the screen?

Once your computer is booting just press the F8 key soon as you see the booting screen ( manufacturer logo ). Windows will then ask you how you want to start your computer. Just highlight safe mode and select it. Then it will start. Into your search menu just type a search for the "appdata" folder. Usually when you are getting some crap it runs there. Just open the file once it found it and click onto the "roaming" file. If you see any program that seems suspicious, just delete it. Sometimes you will see the icon of the program that bothers you onto the desktop of your computer once logged into safe mode. Just delete it as well.

the noise is sometimes caused by dust in the volume control.
i would suggest blowing the dust out around the volume control if there is a manual control on the unit. use a small can of compressed air.. buy it at local walmart or computer store.
