attempting to install rh7 on my system, but before i even get very far in the install process the images get put all over the screen. ie, i get 2 or 3 blurred images of each window. i have a stealth 3 video card. anyone else had issues with this or any other hardware? got a free copy of rh7 at comdex and decided to load it up. not too happy so far. any ideas here?
