Vodoo 5 5500 PCI and Pentium 4

I have a Vodoo 5 5500 PCI card installed in my pentium 4 computer with Win 98. I am having all kind of problems with it. help!!

I do not have a Vodoo 5 but probably can you change the settings for the driver. It is perhaps something you can reach by clicking with the right mouse button on the desktop. Try to disable as many things you can and check the result.
Also make sure that you are using the latest driver.
