Fedora 12 freezes after hardware upgrade

[KAIRU26]

Hello friends,
I recently installed Fedora 12 on my computer. It was working fine until I install new motherboard "Gigabyte GA-EP43T-UD3L" in my computer. After this upgrade my computer starts freezing after some times. I don't know why Fedora 12 freezes after hardware upgrade. Anyone else having the same problem. Please help me to fix this problem.
Thanks in advanced.

I think this problem is related to ATI-graphics boot screen. Most of the people face such type of problem. In this case you have to add NOMODESET to end the grub kernel line to fix such type of problem. After this you will not get any kind of animated boot graphic. It just move toolbar of it, but it will not affect your system anymore.
I hope my suggestion will help you.

If you are suffering from problems with an Intel graphics adapter such as failure of X to start at all, hangs or freezes or crashes in the graphical environment, display corruption, failure of 3D accelerated applications to work properly or similar problems, and your issue is not specifically covered elsewhere on this page, the following general advice may be of use.

First, make sure you have applied all system updates, in case the problem has already been fixed.

Several such issues may be worked around by disabling kernel mode setting. To do this, add

nomodeset

as a kernel parameter.

You have to change to a different acceleration method to get rid out of this problem. To do this, add a line:

Option "AccelMethod" "XAA"

to the Device section of /etc/X11/xorg.conf. If that file does not exist, see How_to_create_xorg.conf for instructions on how to create it.

Hey as per your recommendation I have use both NOMODESET kernel and netinstall disks option, but using I unable to solve this problem. Then ne of my friend said me following steps and that works for me. I think you also use this to fix this problem.
You have to just use following option in /boot/grub/menu.lst to fix this problem.

noapic acpi=off

From your information it seems, you are getting problem due to your new mother board. It may not be compatible with your Fedora 12 OS and that's why you are getting such type of problem. In this case try to use old motherboard and check whether you have same problem or not. If you didn't get any problem, it means that your new motherboard is not compatible with your OS.
