Viper 550 need help

[jrd49]

I have Diamond Viper 550, GA7ZX mother board, with 750 TBird, 256megs of ram, and a 40 gig hard drive, with an Optiquest Q71 monitor.
I am using the original Win 98 drivers from Diamond. The screen moves left to right constantly. I tried the updated drivers from Diamond. They are a little more stable, but I loose about an inch of my horizontal screen size and cannot adjust it to full. Where and what are the best drivers for this card? Thanks

Uh, you can't adjust your monitor?

Check out Nvidia's site for the reference drivers - the 550 is based on the TNT1, I believe.. (right?).

I have tried every set of TNT drivers on Nividia's site. None are stable with this motherboard. I have also installed the Via 4in1 4.25 drivers. No help. The desktop acts as if it's about to jump off the monitor. I guess Diamond Cards and the Gigabyte motherboards just don't get along. Any other suggestions?

I also reduced the AGP to 1X, and set the apparature size to 8 meg.
