I'm not sure if this is the same problem. But my Geforce3 experiences what can only be described as "shaking" whenever I run certain games. The two games where it always happens are Civilization III, and Empire Earth. The shaking on mine can be resolved by DECREASING the refresh rate of the monitor to 60. I know that a lot of people can't hande 60, but that's how I fix the problem on my card.
On the noise issue when scrolling the mouse. It's got to be a monitor thing. I just noticed it now (My room is quiet for once) and if I turn off the monitor and scroll the mouse it goes away.
Anyway, I'm not sure these are the same problems but I have seen the "shaking" thing on multiple computers, always in those games.
