got my rig back today , plugged it all in and switched it on , fired up a game and the sound was good until I got into the main menu of any game I tried.

its a constant annoying beep or buzz that changes key when ever I do something, move my character, pause the game, resume game.

the only way I can stop the buzzing sound is to quit the game. even when im on the desktop it is still there to a lesser degree, very faint but still a little annoying.

I googled a couple of things to try and fix it but I found nothing to help me fix it.

anyone got the answer I need?
 
I tryed the vsync option but it didnt work. What should i be looking to spend on an external sound card ,would a basic one work or would it be a case of you get what you pay for?
 
all i want to do is get rid of the buzzing sound. never realy felt the need for a gamig headset on pc although i have got some turtle beaches that i could mayby connect if i ever bought a proper shooter on pc.
 
i found a usb soundcard for 5 squids (i asked for 10 fresh octopus but he turned me down) at the local computer shop. it might be sketch but at the price it seems worth it to try.
 
If it's one of the gaming-x gigabyte Z97's then it should come with shielding for the onboard sound.
Have you tried using the onboard video only to see if you get a slight buzz still without the graphics card installed?
If it's only with the r9 390 installed then you are a step closer.
What PSU are you using to power it all?

got a 750 wat psu to power it all.
 
this is beginning to be annoying, bought a sound blaster z , set it up and I still get the buzzing sound when I move my mouse and it is still heavily present when I play games. at the moment my games are unplayable
 
my speakers are off ebay, they didn't do this before the upgrade though, 2 towers with five 6 inch speakers ( 2 subs/2 mids 1 high) and a small tweeter.

on the other side of my room there are 3 speakers 2 with a mid/sub or high and a tweeter and the other is a sub box I think(lol) with 2 speakers and a tweeter.

they all go into my technics amp witch takes the sound from my technics graphic equalizer.

iv got a 42 inch telly next to my tower with a ps3 and 4 aswell

the amp and equalizer are above the tower but this didn't interfere with my previous build.

I have 2 monitors , a 22/3 inch for web browsing and the 42 for films/ gaming

Plenty of scope for a ground loop then.

You'll have to go through a process of elimination - first step is to disconnect everything sound related from your PC and plug in the headset - that should tell you whether the problem is inside or outside the case.

If that gets rid of the noise then try removing any other inputs to your equaliser / amp except for the PC.

after your suggestion , I tried it and ended up realising I had to resort to only having sound through my telly for ps3/4. it did eliminate the feedback but the sound is average on my telly
 
The cheapest and easiest way to deal with a simple ground loop if you can't use an optical connection is using an isolation transformer. Should cost no more than £10 for a decent one and you just connect it in-line with the cable that links your sound card to your speakers.

I will have to try that, then if it works i'll have my speakers back for my ps3/4
 
job done, got my isolator and plugged it in just now, tested it on some games with my ps3/4 plugged into the equalizer.

all the feedback has gone and I can enjoy better sound for my consoles aswell as having the sound from my pc all in the same loop.
