Please help me - I seem to have fried the 3D capabilities of my computer! No call to wglCreateContext from my computer works, and no 3D games that use OpenGL work! RealMyst GPFs on me and Driver tells me it can''t find a compatible 3D device. I''ve tried rebooting, reinstalling Visual C++, and reinstalling my computer''s video drivers. I noticed the problem when I was trying to build a release version EXE of one of my demos. I just clicked Project/Settings, chose Release, went to Input and included the libraries, then built the EXE and noticed that my rendering context wasn''t working. Anyone ever seen this???? Any suggestions???? PLEASE??? Thank you!!!!!!!!!!!!!!!!!!! Joe

no, but i once fried my mobo and after that any graphics intesive apps(like minesweeper) would crash the system.

But anyway, if you can get your hands on another graphics card, test it on your machine.

Chack the capacitors on you mobo

CPU temperature?

install older drivers?

test everything and see what happens.

You can''t "fry" the 3D caps of a graphics card. It works or it doesn''t - in the later case, you''d sit in front of a black screen. Your 3D card can overheat, but then D3D will also be affected, as it sends the same commands to the graphics card as OpenGL does.

Conclusion: reinstall Windows. Problem solved.

I meant "fry" in the figurative sense. I just meant that hardware acceleration suddenly stopped working, through Direct3D *or* through OpenGL. Software acceleration suddenly started working again (in other words, wglCreateContext actually creates contexts), I have no clue why, all I did was run the DirectX diagnostic tool.

All I was doing was trying to build a release version of an EXE. Was this probably just a freak thing that happened?

Sounds like a messed up registry entry or driver environment. If uninstalling + reinstalling the drivers didn''t help, then you have a problem. AFAIK, there are some ways to repair the registry, should it come from there. But I don''t know how (I rarely use Windows). The other possibility is to reinstall Windows. What version are you running on ?

What about D3D programs? Do they work?

Windows 2000 Professional. I''ll look into trying reinstalling Windows. My IT guy will have to clear it and that means I''ll have to convince him it''s not just so I can play games .

Direct3D programs don''t work under hardware acceleration either - when I go to the DirectX diagnostic tool and click display it says "Direct3D acceleration not available." Software acceleration tests worked.

Just to let everyone know, I have resolved this issue. I contacted Dell support and they sent me to a page recommending that I install the latest version of DirectX (8.1a). I installed it and rebooted and everything is now fine.

I''m still really curious as to what in the world I did to cause that. I''m still nervous to build a release version because there''s nowhere to upgrade from 8.1a if it happens again!

But thanks to everyone who provided a suggestion.
