Strange problem

[BbBoS]

Specs are

Intel 2600K @ stock currently

MSI P67 Board (Forgot which one it is, can find out if needed)

WD Caviar black 1gb HDD

Gainward GTX580 Phantom @ stock currently

Asus Xonar DX sound card

Mushkin blackline 1600Mhz 4gb (2x2GB)

Corsair TX650M

Last night I was messing around with my computer, re-overclocking it (since I was running it at stock before, and this is a bundle from Aria which came pre-overclocked at 4.8Ghz). Now when I go onto Skype with people, if I am in a game of league of legends or starcraft, my microphone makes a lot of background noise. This has only happened since I was messing around, go BSOD once or twice last night and now whenever I do anything that uses power from my graphics card it seems to make an electrical background noise on Skype. I can hear it myself as well if I record the sound, it seems to change slightly depending how much my graphics card is being used. Can someone help please?

The DX is unshielded so yes its almost certainly electrical interference. Skype has a background noise canceling feature which I have noticed starts to get less effective as a call goes on and is often improved by quitting and restarting the call. So trying that may help you in the short term.

Is it definitely when the GPU is stressed that it happens or could it be related to CPU load and just be coincidental that the GPU is worked hard at the same time as the CPU? It seems strange that you were OCing the CPU and the graphics card being the problem. Another thing I can think of is it being related to load on the PSU mabey? Try running a CPU only stress test and see what happens.

I tried running both CPU and GPU stress tests, and had my GPU overclocked as well (Core at 950Mhz, Shader at 1900Mhz and stock Mem clock) and that made the noise worse. Putting it back to the stock settings has helped, although the GPU was underload since I was playing around with streaming that night as well, although this has never happened before :S .

Hmm...im pretty stumped now. Its weird that OCing your cpu would lead to your GPU making more interference...I will have a think but nothing comes to mind right this second. Sorry to not be more helpful! Technically it would be possible to shield your soundcard but you would have to do it as some kind of mod...

As perturabo said, mostly likely the DX sound card. If your motherboard has built in audio, you could try using that and see if it makes a difference, worth a try
