This problem sounds like it could be multiple things
A Driver problem....
Which is a problem i doubt you have
But in that particular case make sure you are using the newest driver set and using Direct 8 or higher.
Another possibility is that the Graphics card you are using is not working with the mode you are selecting.
This means either the graphics card has had part of its chip set burn out or else the graphics mode you set via the setup program is incorrect...i.e. there may have been a change in the game that has made the Graphics setting you chose incompatible for some reason.
The last possibility is...and I hate to say this....is corrupted data files.
In this case you can try the program on the main site to verify your files, which I am not to sure would help, or you can re-install the program, don\'t worry your character will not be lost.
The second possibility sounds the most plausible though.
I mostly run this game in GL mode with 32bit graphics and at 1024 by 768 resolution.
I believe some other people have pointed out that this mode selection seems to work the best....
If none of the above solutions work, I dont know what to tell you, except that you might have to get a Graphics card to run a field test with to verify if your Graphics Chip set is working properly.
I had a Graphics card develope a similar problem with its chips partialy burning out, it registered it was working, but refursed to do High resolution graphics.
