Windows 7 continually reboots after major hardware change--can't get to reactivate

I upgraded my system Mother board, cpu, and memory; the harddrives and video card are the same.  When trying to boot, the system goes to program starting and then reboots.   I have never had a problem before that at least I could not reactivate by phone.   Any advice would be appreciated. 
I upgraded my system Mother board...

Did you reinstall Windows?

Windows is not designed to be moved from one motherboard to another. On some occasions you can simply install a new motherboard and start the computer, but you almost always have to reinstall Windows when you replace the motherboard (unless you buy the exact same model motherboard). You will also need to reactivate after the reinstall.


You Can Try Repairing The Windows 7 Installation (sometimes it works after replacing the motherboard, sometimes it doesn't work)

1. Insert the Windows 7 DVD and restart your computer
2. Boot from the DVD.
3. Choose your language and click Next.
4. Click Repair Your Computer and then select the operating system you want to repair.
5. Click on the Startup Repair link from list of recovery tools in System Recovery Options.

Too many changes, anew system for all pratical purposes. Need to very hardware is OK. Don't overclock as a starting point.

Set of test utilities for DIY computer builders:
If you are OverClocking or use any automatic overclocking BIOS features then drop back to the stock speed as a starting point.

First try running Memtest86+, this runs from a boot disk or CD and should eliminate or
confirm if your one or more of your memory sticks are bad or the SPD values in the BIOS are correct.
Let it run for as long as you can: 2,4,6,8 or more hours, if no errors by then your ram is OK.
http://www.memtest.org/

If you have a copy of Windows XP around try installing it temporary (if not Windows 7 will work as well)
"No need to activate as you get a 30 day grace period which is perfect for testing"
and then use the following tools (this assumes the memtest shows no failures)

Prime 95:
http://www.mersenne.org/freesoft/
It's a stand alone .exe file contained in a .zip archive.
Just choose to run the "stress test" option for 3 hours or more.
If your PC can pass this test both your memory and CPU
are fine (close the case cover to maintain proper ventilation)

Core Temp:
Monitor the temperature of each core of your processor. For non overclockers using the stock Intel/AMD heatsink and cooling fan you can expect a temperature of 35 to 40C at idle and up 60C to 65C when running Prime95.
http://www.alcpu.com/CoreTemp/

CPU-ID (CPUZ):
Shows the clock speed of the CPU under various load conditions (if you are using Intel's EIST speed step technology). Also has two tabs (Memory and SPD) which show the actual memory speed and 'SPD' tab shows the rated speeds for each memory slot that is populated.
http://www.cpuid.com/cpuz.php

HD Tune:
Provides drive info and has an option to test your drive.
http://www.hdtune.com/

SpeedFan:
Monitors internal remperatures and has an online drive health analysis feature
(SMART tab) for hard drives. It will show how your drives
compares with other drives of the same make and model.

GPU-Z:
A lightweight utility designed to give you all information about your video card and GPU.

HWMonitor:
A hardware monitoring program that reads PC systems main health sensors : voltages, temperatures, fans speed.

PC WIZARD:
A powerful utility designed especially for detection of hardware, but also some more analysis. It's able to identify a large scale of system components and supports the latest technologies and standards.

I have done this type of upgrade before and at worse, telephone reactivation was required.  This is part of the two edge sword of activation.   I have tried repair, it says everythiong is fine.  I can get to a command prompt, but can not use safe mode either.  It is wrong of microsoft not to have a clear and easy way for a customer to do this.  There has to be a way to get around this.

Would reinstallation using upgrade work?  Is there a safe reinstall method? Yes, I do understand the different motherboard controller has to be at the root of this matter.  But there should be a way to fix it.

This was nothing but a base hardware change, I do not overclock or do any unnecessary tricks; in this day and age,  overclocking is totally outdated (just my opinion) and a unneccesary risk.  My computer use is well served by the newer cpus and then some.  Normally I feel memory additions  to a 64 bit system is the best upgrade path, but to use the newer I7 systems I had to change the mother board and memory.

Here is another way to repair the install, but it's not guaranteed to work:

1. Insert the Windows 7 DVD and restart your computer
2. Boot from the DVD. If prompted, press any key to start Windows from the installation disc.
3. Choose your language and click Next.
4. Click Repair Your Computer and then select the operating system you want to repair.
5. Select Command Prompt and type the following commands (pressing Enter after each one):
 
bootrec /fixMBR
bootrec /fixBoot
bootrec /rebuildBCD

What about downgrading to Windows Vista? and then upgrading again?  Any ideas on this.

If you can reinstall and reactivate Vista, then you can upgrade to Windows 7 again. You may need to call to activate.

 

Call Microsoft Using Manual Phone Activation

If you have trouble activating Windows 7 you can call Microsoft to activate by doing the following:
1. With Windows running click Start, then in the Search box type:  slui.exe 4
2. Press Enter on your Keyboard
3. Select your Country.
4. Select the Phone Activation option, then call the number given and hold for a real person.

TrekDozer; I want to thank you for your honest effort to help. 

After I thought about it and got myself out of a activation aggrevation mindset; I realize the issue is not Activation (at least not directly).  It is 100% hardware related.  If the drive is moved back to a similar motherboard, it boots right away.  But I had decided to go to a I7 based nased system, that meant a change in memory type too.  

Being able to change the file written detailing the hardware configuration is the need; I guess at the kerneral level.  Unfortunately researching further, there does not seem to be a safe reinstallation method for windows 7.   It appears too, that at least in my situation downgrading followed by a new upgrade will not work as it at least appears from other information I uncovered, that such requires a clean install.

I understand why Microsoft takes the approach they do, but it fails to solve the privacy problem and does nothing but hurt honest users and in the end, it hurts them.  The hardware file, not only signals reactivation, in this case it stops booting.    I could say a lot more, but I promised myself I would be nice.

Hey, there may  a simple answer out there, but for now, I will simply migrate my system piece by piece.  I do have three licenses and you must clean install to upgrade XP anyway.
