I have a problem with Direct3D. I already ran dxdiag and it had troubles when i clicked the button for test direct3d. I get a blockiness when I do all three of the tests. The same happens when I try to play games that require d3d. Windows XP Pro SP2 Intel D915PBL P4 3.4GHz 128MB DDR2 DirectX 9.0c NVIDIA GeForce 6600GT Latest BIOS and drivers. Can anyone help me out?
