GTX 260 Sli Screen Shaking?

Well just as the question states... In full screen...i get crazy screen tearing and constant shaking from side to side...
Changing to windowed removes it but in the end...usually locks up.

And i cant turnit on without the SLi Bridge as it locks up at boot up. Ive reseated, reinstalled, removed one card, tested each one individually... they both work.
Ive switched them around, just about anything that i can possibly do. And i still get screen shaking in ALL my games.

3dMark Vantage it doesnt happen when i run the benchmark at high, performance or anything. SLI works like it should just
in games it makes my screen shake badly.
