Welcome to Bleeping Computer, jrpop42
Here's the support page for your system, and a link to all of the drivers ...Software and Drivers Deskpro EN Series C850, Microsoft Windows 98
As you will find when you go to this page, there are several different hardware configurations that made up that particular computer model. The trick is to find out what hardware configuration matches your system, and install the appropriate driver. If you do not have this information readily available, and your not big on opening the case to find the make/model listed on the card(s), then you could try SIW.
SIW performs computer configuration, analysis, and diagnostics, and might be able to tell you the hardware configuration of the components in your computer, including your video card.
Hope that helps.
