Hello,There is a horrible static sound on my computer speakers. The static sound becomes too high at times. Its not specific to one set of speakers or headphone. It is consistent in whatever Speaker or headphone I use. I think my cpu case has electricity grounding problem. Could that be the case. If it is, what can be done to solve the grounding issue.

It certainly could be a grounding issue as well as a myriad of other issues.
I would uninstall all my sound drivers and re-install and see what happens.
If the problems still persist i would plug my pc into another wall outlet.

sound card is built in motherboard. Need to check out the motherboard model. Is there any way to check that through control panel or something.

Another thing I noticed is that, I get a mild electric shock if I touch the CPU case while standing on ground. There might be a problem with the casing or the electric outlet. I tried other outlets as well but the problem still persists.

Install CPU-Z and it will tell you.

Regarding getting a shock, does it happen every time you touch the PC?
And what do you mean by standing on the ground? carpet? wood? other? what if you touch a heating pipe/radiator etc first?

I am refering to cement ground, here. The motherboard is msi ms-7309. The static sound is more loud in one of the speakers at a time. If I remove any one speaker, the other has far less, static.

I had a similar problem, my speakers gave a static and somewhat distorted sound.

My solution was to switch the data cable from cd/dvd drive from a 6gig/s to a 3gig/s along with the port I used (6gig to 3gig). I don't know why using a faster port and data cable created this feedback, especially with a cd/dvd drive, but it did. Who would have guessed.

My process, testing sound after every step:
1. Try different programs on your computer to see if the sound came out the same way. Example: WMP and Pandora
2. Try different speakers that you know work for other computers. Example: headphones and actual speaker system
3. Try different outputs. Example: Optical and audio ports
4. Disable any audio effects/revert them to defaults with your audio driver. Example: Default equalizer and environment.
5. Open you speaker properties and go to the enhancements tab and disable all sound effects.
6. In your speaker properties also, go to the levels tab and mute everything but the top most.
7. Lastly in your speaker properties try different sound qualities.
8. Uninstall and re-install the audio drive itself, requires the disk that came with the motherboard most likely. My system uses Realtek.
9. Check all cables to see if they are secure.
10. Move computer to a different location, maybe feedback is caused by something in the area.
11. Try use a different outlet for your power supply.
12. Try using an audio card if you can find one to borrow from someone because they don't come cheap.
13. Where the fun begins. Only use what is needed for you system. No Case, No Fans, No buttons/ports on the case itself. Use only what is necessary; the drive the OS is on, the motherboard, the graphics card. Plug in audio cable/mouse/keyboard into the MB obviously...If it is still giving static at this point, you know one of the things you are using is faulty (the motherboard, hard-drive, graphics card).
14. Place the motherboard back in the the case.
15. Add components to the system testing after each one is installed to see if the sound still works, starting with fans/case buttons/case ports because they are less likely to be causing the problem. Make sure you turn off your system while installing components even though it may be time consuming, you don't want to mess up anything else.

Step 15 is where I found my issue with the dvd/cd drive so don't give up hope.

-I know this is about a year later, but I hope this helps, this is my first post on any forum =)
