I have a working copy of Knoppix 5.0.1 but when I boot from it I get to the "splash" screen (the screen that shows Knoppix 5.0 with pistons in the background) but I don't see the pistons or anything the screen is, for lack of a better term, scrambled. I left it alone thinking it 'might' fix itself but doesn't. I am fairly proficient with computers and I have some minimal experience with Linux, but I am lost as to what to do.

Here is my full system specs:

AMD 3800 X2
BFG Geforce 7800 GT
ABIT AN8
2 GB of DDR 400 Ram


Thanks for any help!
