I have an HTPC that I custome built but am having issues when playing a movie. Whenever I am playing a movie I get a clicking sound out of the speakers every few seconds as if it is thinking or something. Sounds like the same click as if I was trying to open up a file or something. I have closed all unnecessary programs out of the task bar and I do not have any programs installed that I dont need for the computer. Has any one else had this problem?
