Anyone who has a bad stutter problem with a VIA motherboard amke sure when you install the 4in1 drivers that you check the enable DMA box. It helped me a bunch. Almost no stutter at all now.
It gives you the option to enable DMA when you install the 4-in-1's.
Unless he means to enable it BEFORE you install the 4-in-1's in which case you would go to the properties of the hard driver in the device manager (system icon in the control panel) and make sure the dma has a checkmark beside it.
