Hi.

I changed my motherboard yesterday and after that it is impossible to start XP. Everything works fine upto the very first XP-screen (which is mostly black). The moment after this screen is showed, it is replaced by a blue screen saying something is wrong with my harddrive or my harddrive controller and that I have to restart. The faultmessage is "***STOP: 0x0000007b"
It also says that it might be a virus, but I dont think that. I have alwasy had the latset versions of virus programs.

I know there is nothing wrong with the harddrive, as I testeded it with (and even booted) another system (with the old MOBO) just to try.

Does the system need som strange drivers that early in the boot? If I choose to start windows in save mode, the hard-drive copies a number of files, but later the same thing happends.

The new motherboard is a MSI KT4 Ultra BSR
When replacing the MOBO I also changed IDE-cable from 40 pin to 80.

HELP!

This is the fate of our new Microoft. The anti-piracy features have defended.

You may need to revert to your old M'Board and follow these steps, as advised by microsoft [ see:- http://support.microsoft.com/default.aspx?scid=kb;en-us;314070 ]:

The Procedure for Moving a Windows Installation
On the destination computer, perform a new installation of Windows, using the product type that matches that of the source computer. Ensure that the drive letter and %SystemRoot% folder names match those on the source computer.
Using Disk Management, create, format, and assign drive letters to any additional volumes that may be required to hold a system-state component (for example, SYSVOL, Active Directory, or Active Directory Log files). Ensure that all drive letters match those on the source computer.For additional information about drive letter assignments,, click the article number below to view the article in the Microsoft Knowledge Base:

On the source computer, log on as Administrator, and then stop all the non-essential services that you normally stop before performing a backup.
Using Ntbackup.exe, back up the system\boot volume, the system state, and associated NTDS and SYSVOL volumes, if applicable. For additional information about how to perform a backup, click the article number below to view the article in the Microsoft Knowledge Base:

308422 HOW TO: Use Backup to Back Up Files and Folders on Your Computer

On the destination computer, log on as Administrator. If the system that you want to restore is a destination computer, you must restart the computer, press F8 during startup, and then click Directory Services Restore Mode before you log on as Administrator.
Start Ntbackup.exe, click Options on the Tools menu, click the Restore tab, and then click Always replace the file on my computer. Restore the system\boot volume, the system state, and associated volumes from the backup that you performed previously. Make sure that you select the option to restore them to "original location" in the backup program. For additional information about how to restore, click the article number below to view the article in the Microsoft Knowledge Base:

309340 HOW TO: Use Backup to Restore Files and Folders on Your Computer

NOTE: To have access to all removable media (tape or magneto-optic [MO] disk) from the source computer after the full system restore is complete, you must also click Restore Removable Storage Database under Advanced before you begin the restore.

After the full restoration finishes, and before you restart the destination computer, make sure that the computer is disconnected from the network, to avoid conflicts.
Restart the computer.
If the computer does not restart after restoration because of HAL mismatches, you can start from the Windows installation disk to perform an in-place installation or repair. This type of repair occurs after you accept the licensing agreement, and Setup searches for previous versions to repair. When the installation that is damaged or needs repair is found, press R to repair the selected installation. Setup re-enumerates your computer's hardware (including the HAL) and performs an in-place upgrade while maintaining your programs and user settings. This also refreshes the %SystemRoot%\Repair folder with accurate information that you can use for normal repairs.
If the computer does restart after the restoration, log on as Administrator and initiate an in-place upgrade by running Winnt32.exe from the i386 folder on the Windows CD-ROM. This refreshes the Setup.log and registry files in the %SystemRoot%\Repair folder, and ensures that the proper HAL is in use.
Note that in Microsoft Windows NT 4.0, user profiles are stored as a subfolder of the %SystemRoot%\Profiles folder. In Windows XP, if the installation is an upgrade, the existing profile path continues to be used. In new Windows XP installations, a Documents and Settings folder is created on the same volume as the Windows XP installation, to hold user profiles. If the original system was an upgrade from Windows NT, the original profiles will be used after the restore. However, if an in-place upgrade is performed, you may need to change the profiles' path in the registry back to %SystemRoot%\Profiles by modifying the keys under the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

After the upgrade is finished and you are certain that everything works, you can remove the source (original) computer from the network and connect the destination (new) computer in its place.
NOTE: The difference between the time of the backup and the time of the restoration to the new computer may affect the machine account on the domain controller. You may have to join a workgroup first, and then rejoin the domain.

Unless you have info on your HDD that you absolutely have to keep then format and reinstal. If there's data files you need then back up these first. If it's too hard to reinstate your old MOBO to do this then slave your HDD in another PC and backup the files from there.
Your current instal of XP is configured for the exact hardware of your old MOBO and unless the new board is Identical to the old then it will not run. If you run into activation issues relating to your XP version then contact microsoft.

There's another issue here. I've upgrade many times with new MBs and processors, and after flailing around sometimes for days trying to get the OS, whether it's WIN98, Me or XP to work properly, I've always had to fdisk and do a clean install. Bottom line: you can't just put the bootable drive from an old MB configuration into another MB configuration and expect it to work properly. If you get it to work, you're damn lucky, as the built-in devices and BIOS of each MB have a high probability of being quite different, even for MBs made by the same company. This is part of the chaos that reigns in the world of MBs.

My copy of XP is activation free (dont remember what the activation free ones are called) so I dont think that is the problem.
I will try the repir feature of XP. Otherwise I just format the whole thing and reinstall.
I just dont want to go through with the total reinstall if this is a hardware issue. Then I will be doing all this reinstall work for nothing, on top of loosing the latest info.

I am good at taking backup, so thats no big issue.

Thanks for the input!
