Video card - lines streaking aross desktop

[mrappe]

I just bought a new harddrive for my windows computer (300 G) and installed FC6 X86_64 AMD and Win XPPro SP2 on it.
The Fedora install went smoothly with the graphical install. My video card (GeForce4 MX 440 ) was recognized but when I booted it up the computer there were a lot of thin lines streaking across the display. they are more noticable with dark backrounds . I have a Samsung SynchMaster 730b monitor with 1280 x 1024 native res. When I boot up Windows I don't have any of the lines. I am thinking about replacing my old video card anyway with a GeForce 7600 GS card. Do these work OK with FC6? If I do change cards how do I go about switching? Do I need any new drivers?

Thanks
Mike

I am thinking about replacing my old video card anyway with a GeForce 7600 GS card. Post the output of cat /etc/X11/xorg.conf and we'll see if we can help you with the existing video card.

This is it:

Be absolutely sure these are correct.HorizSync 30.0 - 81.0
VertRefresh 56.0 - 75.0I think they are. Then make this "1280x1024" "1280x960" "1280x800" "1152x864" "1024x768" "800x600" "640x480" look like this "1024x768" "800x600" "640x480" and restart x to at least see if you get 1024x768. Then you can go forward from there.
