Every few minutes to a hour my audio does this stuttering sound and either the ingame video I am running will stuttering or a slight screen freeze if I am not playing anything. It will only happen for a few seconds then go back to normal. I am not sure why this has started happening as the rig I have is custom built. At first I thought it was iTunes as it happens more often with it running but it occurs even with iTunes off.
If you need additional information I will reply as soon as I can. Thanks in advance.
