Installed graphics card and now sound is static

chrisgritz · Jun 14, 2018

Hey guys so is installed a graphics card on a computer and after i installed the graphics card i plugged in the cable jack and i got only but static. I tried to uninstall the drivers and reinstall and still got the same thing. The only thing that is working is the USB headphones. Any recommendations? I was thinking that the power supply is maybe not enough? or maybe its because static built up in the motherboard? aren't there 2 little pins that you can switch over and press the power for 30 secs to remove all static? idk im confused right now. If anyone has any input, i really appreciate it.

Check to see what is the default playback device. Graphics cards install sometimes changes it to their digital output and your motherbd & audio jacks would probably be using Realtek HD or something similar.

how can i check that? It is currently set to realtalk device and i can see the waves going up and down when playing a video on youtube but i get no sound and only static. i tried changing the graphics card back to the normal one that it had its still the same thing.

Check that you did not disconnect the Front Panel audio connector from the motherbd to install the GPU. Its often in the way.

what would it look like ? btw ive connected to the back and forward audio jacks. All static.

That's not good.

Sounds like something is shorting out the audio outputs then.

damn i didn't know installing a graphics card could cause that, what tools do i need to ground myself? If you have any recommendations on a another site. We are planning on building another computer and don't want to risk it.

A ground wrist strap or when you build you can just constantly try to touch a bit of bare skin on a metal part of the case. I build resting my fore-arms on the case edge and only wear a wrist strap when I'm stuck in someones cheapo plastic case.

Try not to touch a board except by the edges or parts that aren't electronic.

Remember that a PC isn't really off unless its switched off on the back of the PSU or unplugged from that wall and you shouldn't work on the inside of a pc unless its off.
