Lines of static on screen when playing Nascar 4

Well, as soon as I fix one thing, something else happens on my other system. When playing Nascar 4 in Open GL mode, framerate is really horrible and there’s a line of static 3/4 up the screen. I am hoping this does not mean the video card’s already shot…it’s not even a year old.
System Specs:

AMD Thunderbird 1.2 GHZ
GeForce2 MX 400
Shuttle Motherboard (VIA chipset)
Windows 98 SE
I have the Dets.

I get the I get the flickering line thing with a geforce 3. But i dont think that there is much that can be done about it. Check that your monitor isnt running at 60hz i downloaded a refresh rate fix and that kind of cured the problem.

Well, it’s on Optimal…vague, eh?
