Failure initializing OpenGl

[tanis]

Hey,

I first noticed trouble when I tried to load NwN and it wouldn't display the game menu properly (just gave me a blank screen but I got the hand cursor). Then loading CS wouldn't work either - it said that "this video mode" (OpenGL) was not supported, so it was forcing a switch to software mode. Finally, I downloaded SiSoft Sandra, and under OpenGL properties, it displayed an error saying that it couldn't initialize OpenGL.

Specs:
P4c 2.8 GHz
1024 MB PC2100 RAM
ASUS P4S-8000D-E Mobo
VisionTek Xstasy GeForce Ti-4400
Windows XP Pro
DX 9.0
(full system specs here)


This has always worked - and it just suddenly didn't work today. Been always running on the 53.03 drivers (the newest version for NVidia cards) and it's been fine 'til now.

I have currently tried running old drivers, and uninstalling and reinstalling the 53.03 display drivers. Neither worked. I've also Googled around for possible solutions, but the only one I've found so far involves commenting out a "DVA=0" line from WIN.INI, which I don't have (the line, not the file).

Has anyone ever experience something similar, or, short of reinstalling Windows, does anyone have any suggestions?

Thanks.

Hmm. Ran a virus check lately?

Other than that, have you installed/uninstalled/changed anything that might spontaneously break your installation?

Thanks for the quick reply.

I have Norton2K running on the background constantly updating and performing incremental system scans - and it usually catches viruses before I can even access them. I've also run a full scan without any results.

The only thing that I have installed since before it stopped working is ICQ2003b, and I doubt that would do anything to my video card.

One thing I should note though: after NwN first started failing, I did first go to VisionTek's site to download their proprietary drivers and installed those over the 53.03 set in hopes that it would work. (That's what I meant by trying old drivers). When that didn't work, I reinstalled the 53.03 drivers and THEN downloaded Sandra and ran the diagnostic. And as mentioned before, after that, I uninstalled the video card altogether and did a new, clean installation of the 53.03 drivers. Unfortunately that didn't do much.

What's odd though is that I *can* access my OpenGL settings from the NVidia Display Properties Console. I've fiddled around with the settings to no avail. (There aren't many: Disabling/Enabling support for enhanced CPU instruction sets (enabled by default), Enabling/Disabling conformant OpenGL texture clamp behavior (Disabled by default), Default color depth, Buffer-flipping mode, and VSync). So in a way it seems that the NVidia software thinks OpenGL is enabled, but Windows is convinced otherwise.

As a last note - when I tell CS to use OpenGL at a certain resolution, it will attempt to change it - and succeed, but immediately bounce back to desktop within a second to say that the display mode is unsupported. So for a split second, I *do* see the screen display properly (using OpenGL, I would think), but then something decides to cut it off and say "You can't do that."

Thanks again.

Installing driverset over driverset is bad karma. Go get "Driver Cleaner". Install it, then remove your drivers and network cable and boot into safemode. Run DC and kill every driverset you find. Reboot back into normal XP, then cancel the auto-install and run the 53.03 setup exe. Once rebooted again, then you can plug your network cable back in.

I will try that, thanks a lot!

Just tried it - SiSoft Sandra now shows OpenGL to be working.

Mercenary, I owe you hours and hours of headaches saved for that one. Thanks a lot.

Test it in-game before you thank me.

Haha. Both NwN and CS work normally again, as expected. Even if it didn't work, the worst case scenario then would have been reinstalling the game anyway.

Thanks again.
