Discharging static electricity? - Page 3

post #21 of 32
Thread Starter 
...ok now i have another question, i get a weird buzzing sound from my FRONT headphone jack only, its as if i can hear my cpu or hdd working, for instince if i go to my desktop and highlight a few folders then i can hear the processor (?) through my headphones? but i HIGHLY doubt its from static discharge as i first exchanged the chassis because i thought it had faulty wiring but the buzzing continued so i exchanged my mb for a BRAND NEW ONE, and the buzzing continued, however i dont get the buzzing from the back jack, its completely crystal clear! what could this be?

Most likely a bad ground connection to the front audio jack. Recheck all connections just to be sure that's not the culprit.

I'm not entirely sure how to. It's gonna end up being a case mod, that much I do know. It'd probably be more worthwhile to just use the rear audio jacks, and have an audio extension cable going from them so you don't have to get behind your pc every time you want to plug the headphones in.

Not true. ESD can also damage the components on a lifespan level causing them to fail much sooner than they normally would under regular wear conditions. But not always immediately as if they were zapped to death.

If you hate gloves you can even go just fingers. Honestly, wrist strap or gloves would be the easiest things to use.



Most ESD equipment is passive and is eventually plugged into the ground socket on your wall outlet. That is what your case is grounded to and why you need to plug your PSU in for it to be grounded.

Thank you for caring about ESD op. On a personal level I have noticed a dramatic difference in my own hardware's health since I started taking precaution. It is not a myth as some people on here may tell you. I have been trained and re-trained in ESD procedure, cause and effect, looking at ESD events with an oscilliscope. For some reason the majority of people on here think that it's like wearing tin foil hats.


RetroAction: I'm not an audio expert, but I'm thinking something along the lines of the audio's power circuit not being very filtered from the rest of the board. I usually only notice it with onboard and headphones. I'm sure there's an article on it somewhere.

what do you mean its not filtered very well? anything would help really, im just looking for an explanation not a "fix", im just confused as to why a brand new mb (twice) would have this issue.

All it takes is one direct hit to something on any one of your PCBs, and then that component becomes a fancy paperweight.

For example: you can kill some of your USB ports by sending a direct shock (even a tiny shock) to that metal box housing. Worse yet, you might screw up some other parts of the motherboard at the same time.
Yep. My kid put a paperclip in my USB port and it killed my motherboard. this was back in 2007. Gigabyte RMAed no problems though, good people.

It's just a motherboard issue which is very common with the front panel header. Speakers usually aren't sensitive enough to display it but headphones are. Is it EMI... grounding issue... filtration... I have no idea. It might be down to the board. Grounding the jack housing will probably not do much. Mobo manufacturers have probably have neglected to prioritize it as an issue. It's been an issue for a LONG time. As long as I can remember on AC97
