This issue came up when I tried to use Project 64 (Nintendo 64 emulator) on my computer. I installed it 3/4 months ago, used it quite a few times, no problem. Then recently I tried to use it and received an error message: Direct 3D failed to initialized Error Code: 8876086A D3DERR_NOTAVAILABLE I guess this means my plugs in have not inlialized. I run dxdiag and I can see: DirectDraw Acceleration: Not Available Direct 3d Acceleration: Not Available AGP Texture Acceleration: Not Available I haven't done anything to change these settings, so why would these be turned off? I use a NVIDIA Geforce card, and it is enable d with the latest driver installed. As I said, I used this programme before, so why would these be turned off and how? More importantly, how do I rectify this? I know with Vista you can't turn on/off hardware acceleration.

System restore (restore point) might be the place to start. "Best Practices", Event viewer, host file, perfmon, are in my top 10
