Weird screen at startup

[vitorferreira]

H, i have a new imac 27" 2.66 quad i5...and since yesterday a weird screen has started to show up on startup, right after the loading screen with the apple logo in...a gray filled with vertical stripes appears for a milisec...then it´s gone...anyone knows whatdoes this screen means?

cheers

My i7 started that after installing 1.6.4 - most likely just a driver issue.
