[h3r31am]

I just started installing iATKOS 3s this morning so bare with me. I looked all around the net and cant find the solution to this: I finish doing the disk utility press continue and go into customize option and dont know what to choose.

 

1st attempt: Restart Computer Error.

2nd: Hear music but no video

3rd: Hear Music and see part of video in very wierd blocks scattered areound the screen.

4th: Same as 1st

 

Everything else seems fine (Mouse, Keyboard, Speakers, etc.)

ATI Radeon 4600 series 1GB (think 4670 but says 4600 series in device manager)
