Guessing: the old motherboard supported a LBA-disk addressing mode
that's become passé and the new one doesn't.

I'm assuming there was a kernel update in there, so grub would have
rewritten itself to disk.
I don't know what's going on, but there's some thing where when you
boot off of a CD the OS inherits some BIOS parameters that might be
different from when the kernel boots from disk. I have a machine
that will boot from DVD but the kernel can't access the drive if
booted from disk. I haven't been able to figure out what's actually
going on there.
Once or twice I've been able to take a machine in a state like yours,
boot from the Fedora rescue CD, chroot to the sysimage and run grub-
install to get things working again. Obviously, really understanding
the problem would be better.
Just a check, there's not a hda->sda problem here, right? Make sure /
etc/fstab is accurate, and run mkinitrd if you need to fix it.
