Out of Scan Range error
 

I had Fedora Core 1 and Windows XP installed on my machine with partitions set up to dual boot. It took me two days to get everything right but I did get it working great. Then, my motherboard died so I had to replace it. The new motherboard has on board video (my other mother board had a video card) and the X Server doesn't seem to like that. Whenever I try to boot up Linux (or even reload it, for that matter) everything works great until the X Server tries to initiate and then I get a white box that pops up with an "Out of Scan Range" error message. It is obvious that Linux can't recognize the new video configuration but what can I do to fix this? I'm a total newbie.

Thanks.
