3D images stuck the old scoring

I am integrated motherboard, I just installed a 7600 GS graphics, 3D measurement of the screen Score, the old image stuck, sometimes very smooth, sometimes stuck on, how the case!

integrated graphics common problem, a lot of heat when the 3D rendering, integrated high-temperature transistors, resistors signal line changes, the overall performance of La collapse, the card is not strange.Sometimes Sometimes card is very smooth, Oh, this is the integrated graphics processing in the 3d graphics at the time of instability.You add graphics to integrated graphics on the Main Board, set up to switch off on the trip.Add 300 or so cards than This strong.
