A problem occurred initializing DirectDraw. Hardware acceleration maybe disabled, please run DXDIAG.
A few weeks ago, I tried to load the PC version of Halo on my computer. It had always loaded fine in the past, so why would it not this time? I was prompted to the above error, and I have tried everything to fix the problem. I installed DirectX 9.0, I re-installed the drivers, and still, the problem remains. I have games I want to play, and I cannot play them! Please help.
