Hi,

I cannot start games and demos that uses OpenGL. DirectX on the contrary works just fine.

My system is

AMD Athlon 2100+
1Gb RAM
Gigabyte GA-7VRXP Motherboard
GeForce FX 5600 128Mb Graphics

I use Windows XP SP1

I have tested the graphic card in another computer, and there OpenGL works just fine. Previously i had a GF4MX and encountered the very same problem.

I also had a windows 98 installation, and linux installation before and had no problem to use OpenGL in either of these Operating systems. Though I had the same problem in Win2k. I was thinking about migrating to linux, but then Final Fantasy XI was released and I'm stuck in windows.

The strange thing is that when my WinXP was newly installed, i did not have this problem. But then it came from nowhere, but I cannot put the event in connection to anything that I have done. If I would reinstall WinXP i quite sure that everthing would work.

I use nVidias latest drivers.

I would apprechiate any help on this matter.
sincerely - marjasin

When you went from the GF4MX to the FX did you completely uninstall the old drivers and reinstall the new ones?

It is exactly the same driver...

Yes I know. But sometimes it makes a difference.

Im having the same problem. I reinstalled drivers countless times, reinstalled DirectX, I even bought a new card. Went from GF3 Ti200 to a GF4 FX 5600 Ultra 256mb and Im getting the exact same error when trying to use openGL.
says Driver component sizes mis-match. Oh yea and I "upgraded" windows again to try to rewrite any possible missing or old files.

New card, week old.
My card runs well for quite a while then the screen gets all grainy and kinda broken up.I have the lastest driver from nvidia site. It won't cut out or anything,,, just looks like crap. Not a lot of heat in the case,,have 5 fans running. Any ideas??

I am having the same exact problem, but with a Geforce 5600go on a notebook computer.

I found out that going into the device manager, uninstall the video card, reboot, then after re-detection, OpenGL works fine. Stand by mode is disabled though

But if you reboot again, OpenGL stops working again.

Reinstalling WinXP indeed solves the problem, but it pops up again after few days for no significant reason

Anyone has a clue on this ?

Hate to tell ya but, I couldn't get it to work correctly. I tried everthing believe me.
I got rid of it and installed an ATI 9600xt, NO MORE PROBLEMS.

err

anyone has a more optimistic answer ?

So, should I understand that we are like 3-4 people that experienced the _same exact problem_ and that no solution other than "switch to ATI" has been proposed/found ?

wtf
