Nvidia ION drivers causing problems for anyone else?

[Scionix]

Hey guys, since updating to the ION drivers released May 7, I've had hosts of problems. When running games, half the time the display will just lock up, turn a solid color, and hard crash my PC. No idea how this is happening, as sometimes the programs will randomly work, and toggling SLI does nothing. Anyone else having issues? I'm going to roll back and see if it solves the issues, fingers crossed >.<
