Quake II, My graphics card, and a new error.....Please hel..

Hi all,
I just recently built a new machine 3.6 GHZ, Gig and ram, and a Leadtek
WinFast PX6600 TD Graphics card. I ran out of money on the card so I
got one that I thought would do everything I need. I am developer so
mostly this card will be used in the development of software that is
not graphic intensive and mostly for business work.

I like to play Return to Castle Wolfenstein , Quake I, Quake II, Quake
III. So I am getting things finalized on the machine. I got Quake I and
II to work but could not get RTCW or Quake III to run. In the mean time
I purchased Halo and MS Office 20030 and installed both. I was reading
a document on the Microsoft website about Direct X and Halo and how my
card was not set to the highest accerleration in windows. I set my
accerleration up and tried my apps again. Quake I worked fine (GL
Support),Quake III worked Fine,Halo worked fine, Return to Castle
wolfenstein worked fine but when I tried Quake II it dies right after
the opening "ID" screen with a application error memory cannot be
written error. This is in the QuakeII.exe file. Now, I am curious what
would cause this as it ran before?

I have not played most of these games in about 2 years at least and I
trying to remember did Quake II come with a open GL version and non
Open Gl version? How should I try and fix this? Can I turn off Quake II
GL support?

I have turned off accerlation when trying to run Quake II no change. I
have the Latest Direct X drivers installed from Microsofts website
9.0c. Latest Service Pack for Windows and the 3.20 Quake II patch. I
have no mods as I am just installing. I have tried uninstalling and
reinstalling.

Is there anything else I can troubleshoot? Suggestions....Please
help...

Thanks,
Chris

Jimmy,
Thanks for the links on the .net stuff being a developer this is very
interesting to me.

Also its funny but both the native and the .net versions of the
executable run fine.

Thanks again for the help,
Chris
