XP loop-booting after motherboard upgrade

[CheetahMk2]

Hey everyone,

I recently got off a K7S5A Pro 5.0 and moved to a MSI KT6V, but my system would just flash the 'Windows XP' loading screen at the bottom, and the bar wouldn't even go left-to-right even once before the computer physically rebooted.

I went back to my old motherboard, but that wouldn't boot at first either. After manually restoring the registry from a Prinstall Environment, it worked, and I went and followed the intructions here for SysPrep. I 'repacked' it, and swapped mobos back, but it still is loop booting.

When I go to safe mode, the last thing I see flash on the screen is mup.sys, but I believe the problem happens after that and just isn't shown on screen. I cannot tell if there is a BSOD before it reboots because it does it too quickly, and the monitor is off when it does that.

Does anyone know anything I could try to get it to boot into windows with the new motherboard? Either that, or delete the HAL hardware profile [Hardware Abstraction Layer] so it redetects all the cards from scratch?I
d rather not reinstall on top of this, as I have tweaked Windows out to the point where it is respectably secure and user friendly.

If you want to know something, just ask. I figure the people in here have experienced the problems of swapping motherboards before.

Ok... tried repair install a couple of times to no avail, and even then the farthest I got was approximately one second into the loading screen.

I guess I should have used sysprep -pnp -reseal. Regardless, I am about to just reinstall. Rename Windows dir and Documents and Settings so they aren't touched by the install... then just do a clean install and hope none of my data is touched.

Changing a motherboard can cause much confusion for Windows XP.

You can do a delete install. It is a feature of the Windows XP installer. It leaves EVERYTHING the same - all your directories, Program Files, Documents and Settings - and only deletes the Windows directory, then does a fresh install. You will have to install drivers, plus any programs that installs required stuff into the Windows system directory or the registry would have to be reinstalled.

Yeah, I got bored last night so I just renamed the Windows and Documents and Settings directories and just reinstalled. It didn't detect a previous installation, so I guess all went well. But my security permissions are a mess now, I have to reset everything back to how it was, preferences, TweakUI, it's going to be a pain.
