hangup at gagp30kx.sys

Hello
I have a windows xp home machine that will not boot. Hangs while loading the driver gagp30kx.sys and reboots. I booted to a PE Builder disk and renamed and replaced this file with no luck...same thing.
So I was just going to do a repair however the setup looks for a existing windows installation but I don't think it finds it for some reason.
I just get the option to setup windows on the existing partition.

Any ideas.

 

it's agp video related. check u'r bios for updates and MB maker's site for chipset updates.

 

Corrupted registry

I am sure that it is a corrupted registry. Last Know did not work of course.
I can boot with a Barts boot disk. What I want to do is copy hives from the windows\repair to windows\system32\config but this is an oem version and I read this would not work. I wanted to get to safe mode so that I could use the system restore.
So basically I need to be able to repair my registry enough to get into safe mode to do a system restore.
I was able to catch this error before it rebooted.
c0000218 {Registry File Failure}
Any ideas?
I can do a parallel install but I would like to repair this if possible.
Actually, I stuck an old hard drive in and reintalled windows xp with no trouble.
Thanks in advance!
