GeForce 6200 issue (odd, but an issue)

Hey all, back again with another odd tech question!

So a GeForce 6200 AGP 8x(128) dropped in my hands, so I swapped out my old GeForce FX 5200 AGP 8x(256) for it.

So far in most of the games I play (older games, WoW, ET, DoW) it hasn't been an issue.

So I went to LAN with a few buddies of mine at my office, and we loaded up WC3 Frozen Throne. The screen is....like Vibrating while the games on screen. I assumed it was something similar to when I had the issue with my FX card, the refresh for the monitor was to high (70 vs. the 60 it needs). I checked the settings, but it was set at 60. Is the game possible increasing the rate? If so, why didn't this happen before? Odd right?

Anyone have any thoughts? Drivers are up to date.

 

cud be a monitor problem, try swapping monitors with ur buddy and see
