Hello, I'm not sure if I have put this in the right forum, but I experience very loud noise problems from my PC, I have had them since the first day I've had it. It is a custom built PC sold on eBay, with the specs below, I had to add a graphics card, and change the power supply to accompany it. Even with the old power supply and without the graphics card it was still loud. The last custom built PC I had was loud too. " CPU AMD Phenom II X6 1090T Thuban 45nm Technology RAM 8.00 GB Dual-Channel DDR3 @ 669MHz (9-9-9-24) Motherboard ASUSTeK Computer INC.

Any explained help would be greatly appreciated. Also the PC seems to have a random stutter problem, when the mouse would seem choppy and the audio would seem distorted, for a split second. Thank you very much.
