When Playing Halo I recieved the error message that DirectDraw accelleration is not available so I went to DxDiag and it says "Not available". The Approx Total Memory shows as "n/a" and the first DirectX Test (Hardware accelerated DX7) fails with an "out of memory" error message. I have a ATI Radeon HD2400Pro made by MSI. When I use any drivers other than the ones from the cd (I think it's 8.33) the system goesd slow, with CPU Kernel times above 90%. Please Help! _____ ATI Radeon HD2400Pro AMD Sempron 3200+ 1.5GB RAM MSI AMETHYST-M Motherboard 3 HDDs on IDE (80GB, 40GB and 20GB) _____ I have tried a clean boot, disabling remote desktop, disabling remote assistance, disabling remote desktop sharing in netmeeting, and disabling write combining. The hardware accelleration slider is on full. my DX runtimes are the latest. I don't want to format. DXDiag log attatched. DxDiag.txt
