I am using 2 GTX 460's in SLI. This only occurs in Google Chrome. Internet Explorer is fine.
With SLI enabled man websites, to include tomshardware will flicker black. Scrolling down will some times cause it to stop, other times cause the screen to stop on black. With SLI disabled everything works fine.
I have google searched with no luck.
Steps taken so far to fix the problem:
Re-Installed latest NVIDIA Drivers. Uninstalled and Re-installed Google Chrome
