strange screen error

[attila]

After upgrading to v0.08 and removing the crossfire adapter (2xHD5970 cards) my system screen begin to be filled with garbage. Does someone have an idea how to correct the problem? If I want to make a screen-shoot nothing strange on the saved image, I had to take a photo from the screen. If I move an open window the garbage disappear behind the window. The machine working well but a little instability appeared. I can not put back the crossfire adapter because changing the fans to arctic coolers. Thanks for the ideas!
