I tried to change my motherboard and CPU from a 1.7GHz AMD Athlon CPU and a VIA chipset Motherboard to a 3.2GHz Pentium 4 with an Intel chipset motherboard. When I tried to boot the machine the monitor would loose synch and it would reboot. This system is running Windows XP Home Edition with SP3. I also dual boot OS/2 with this system and it boots and runs just fine so I don't think it's necessarily a hardware problem. Has anyone run into problems like this when changing Motherboards?
Thanks,
Sam

Yes, Windows is now trying to run on hardware that is different to when its Hardware Abstraction Layer was set up.

You will need to do a Repair as detailed here:

http://support.microsoft.com/kb/824125

and once Windows is operating again, install the drivers for your new hardware and do a Windows Update.

It's likely you will also need to re-activate Windows.

When you take a hdd with a Windows OS installed on it that you have been using on one computer and then install it as a master in another computer you are asking for major problems. The excerpt below is from a Intel article which describes in detail what happens. The article also mentions a reference to an article by Microsoft, it can be seen here .

"Moving a hard drive with Windows* 2000 or Windows XP* already installed to a new motherboard without reinstalling the operating system is not recommended.

If a hard drive is moved to a new computer, the registry entries and drivers for the mass storage controller hardware on the new motherboard are not installed in Windows for the new computer and you may not be able to start Windows. This is documented in Microsoft's knowledge base article. This is true even if you move the hard drive to a motherboard with the same chipset, as different hardware revisions can cause this issue as well.

Additionally, moving a hard drive to a new motherboard may not exhibit any errors until you install new IDE drivers. This is because each chipset uses a different Plug-n-Play (PNP) ID to identify it. If you move your motherboard, your registry will have multiple PNP IDs (for the old hardware as well as the new hardware). If there are multiple entries in the registry, Windows cannot determine which hardware to initialize and therefore fails with a STOP error."

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I tried to do the repair as per the Microsoft kb824125 article. It prompts for the Administrator password and then just goes to a C:\Windows> DOS prompt. I reinstalled the original Motherboard and tried to log in as the administrator and I get a dialog window saying that the Administrator account is restricted. I guess I have never logged in as the Administrator on the XP Home Edition system. The management console doesn't have the users and the User Accounts control panel object doesn't show the Administrator account. Am I just stuck here? This seems really strange to me.
Thanks,
Sam

With the new motherboard in the system, proceed with the instructions "Replace a failed motherboard", as you have already replaced the motherboard.

"Replace the existing motherboard with the new motherboard.
Insert your Windows CD in the CD-ROM drive or the DVD-ROM drive, and start the computer from the CD.
When you are prompted To set up Windows now, press ENTER, press ENTER.

Setup looks for any previous installations of Windows XP on the hard disk and then displays a list of any previous installations that it finds.
Use the arrow keys to select the installation that you want to repair, and then press R to select the To repair the selected Windows installation, press R option.

This will start the repair of your previous Windows XP installation."
