"rundll32" error messages typically tell you in which module they occur. You didn't mention this. You might try looking at this web page to see if your problem is listed.

I reviewed the link and did not see anything that applies to my issue. Again, When I click on the Settings Tab in DISPLAY (Under Control Panel), the computer freezes and I get the message "RUNDLL32 An Error Has Occurred in your program. To Keep working Click IGNORE......: However, I can not click anything because the computer is frozen so I need to powerdown and reboot.
The error does not specify any module or address. Very generic error message. I just removed and reloaded the Display Adaptors (both the Intel and the GEFORCE Driver) but still can not access the Settings under Display.
Is there as possible software issue with the WIN98SE for the DISPLAY? I know the adaptors are not corrupt since I removed and reloaded. Any other ideas?

I'm not sure I can be of much more help under the circumstances, however, I might suggest that you do these things.
1- Visit http://www.visiontek.com. Click on Tek Support on the left, and then on Vision Tek Forum. I believe the forum you need is Legacy Vision TekProducts. Register, if you are not a member, and then start a new thread about your problem.
2- Failing that, contact VisionTek's technical support at support@visiontek.com and e-mail them a description of your problem.

Either of the above may provide the assistance you require. Good Luck and please post the results here for the benefit of all our forum readers/members.

if you use the nvidia manager that is installed in the system tray you can change the resolution that way i had the same problem just now and it looks like you posted this a couple years ago so you probably have already fixed this or at least upgraded OS. if you have a question or dont understand this message you can email me or private message me.
