Video Mode change failure?!? The specified video modes is not supported?!?

Hi, I have this problem where whenever I try to change the video settings to Open GL in Counter-Strike through Steam this error message will pop up:

Video mode change failure
The specified video mode is not supported. The game will now run in software mode.

Yeah so does anyone have any ideas why this happens? I tried doing that thing where you place the opengl32.dll file into the C:/windows/system folder but the error message still pops up. I believe I have downloaded the latest graphics drivers for my video card and I think I’ve dled all the latest drivers for my motherboard and yet Open Gl still won’t work…Any help/suggestions/tips greatly appreciated. Thanks for your time!

Here are my system specs in case your wondering:
Microsoft Win 98
2nd Edition
Authentic AMD
AMD Athlon™XP2000+
256.0 MB RAM

NVIDIA GeForce FX 5200
CMI8738/C3DX PCI Audio

Road runner cable + Norton Antivirus 2002, Norton Internet Security Family Edition

Sounds like a Counter Strike problem… might try them for support…

(Shockingly, the problem could be because “The specified video mode is not supported”.)

Does it run in a window?
