I have built an OS on susestudio.com 64x and im trying to install it on my AMD A6 Quad-core system wit ATI Radeon Graphics and thats my problem. everytime it gets past GRUB it show 3-4 black bars at the top of the screen and the rest is yellow red pink black white and blue Fuzz like on an old TV when it doesnt have reception or Snow. im using a preload iso and im installing to a usb Hard Drive.

Im new to Linux so this is proving difficult for me

any help is appreciated!
