Activation of Windows XP After Losing Original PC Board & Casing

Recently, I had a board-crash on one of our legacy systems and so, had to replace the motherboard. However, this being the second time the HDD was moved, we can't trace the initial PC-casing to enable us retrieve the original product key that came with it. Is there a way to fix this without formatting the HDD? Please advise.

Please contact the microsoft. Give yours detail information. They will activate your copy.
Please tell him what is the reason behind that.

Three times it should be allowed to change XP license from one computer to another.

Try connecting the old hdd to the new motherboard.
if it boots then you can continue working without formatting.

only thing is you have to download the drivers from the board manufacturer website.

Either way I would contact MS.  If you are able to boot and load into windows it will create a long code and you will be able to activate via their automated telephone system, alternatively you can speak to an agent.

Before going ahead with this, read nobus' article on the subject to be sure that you are still legal.  Microsoft may consider a board failure in a legacy system to be expected failure in the course of time, and not a "defective" product.
It really boils down to the type of XP license you are using. If it is a limited license type (OEM) then the activation process could be negatively effected when it recognizes that there have been hardware changes. There is a limit of allowed hardware changes for these types of licenses. Too many changes are seen as it being a new PC which will void the activation. No matter what you do you will have to contact the Microsoft Activation department. Just explain that there was a power surge in the house and it fried your PC. They will most likely reissue the activation tolerance of the license, resetting it basically. This will however depend upon how long you have been using the license. Best of luck =)
Retrieve the key thats in the system currently.....

ProduKey v1.45 - Recover lost Windows product key (CD-Key) and Office 2003/2007 product key.

If needed, build an install CD off of the files on the drive if they are present, that way you know they will match up.....

 Create a bootable XP CD from your I386

What license type is this?  If it's an OEM sticker based install then you'll need a new license.  See:
For a retail license just extract the key from the old registry.  If it's part of a volume licensing arrangement carry out a "repair reinstallation" with the VLK media to activate it.
Use:  if you can get the system up and running.

To resolve this, I finally located the initial machine chasis that came with the HDD and copied the XP product key from there. Next, after changing to this product key, I called Microsoft to activate without hassles.
