Solved chnaged MB and cpu no boot, BSOD

January 15, 2013 at 18:45:37
Specs: Windows 7, i5

I recall xp used the MB cpu and HD to make a key for the OS for some silly protection. I was not aware windows 7 did this but maybe that is my issue?

I just installed the new hardware ( brand new cpu and mb) and I get a blue screen. Naturally I can not see it as its only up for a second or less. I tried win7 repair and it told me errors were found but can not fix then offered to send this information to Microsoft. I then tried safe mode and it also blue screened on me. all other hardware was working before the swap and I dont see any issues.

Does windows 7 have this copy protection in it? If so how do you upgrade parts as there no longer is a windows7 upgrade ( install over its self ) option. ?

How can I see my BSOD error if I can not boot at all?

I upgraded from AMD to Intel.
I have win7 64 bit
no hardware other then cpu, ram, mb, vga.

ok I was able to capture it with a cell phone. looks like the fist part of the dump is 0x00000007b the other numbers are very busy like oxfffffff...

also when I run memtest it restarts the system before the main screen loads.

Windows 7 installation, especially a factory installation is hardware specific. if the motherboard is changed, with a retail installation, you might be able to reload the drivers or do a repair install, but it is my understanding that with an OEM installation, it is tied to the original hardware.
If it was just Windows 7 that would not boot, I would say try booting to Safe Mode and installing the drivers and see if that works but since you also had difficulty running Memtest (presumably form a CD or flash drive), you need to assume that the problem is hardware related (though you still will probably have trouble with Windows later).
Recheck everything.
Remove everything but the basics and try it that way.
Strip it down and bench test it.
Are you sure that the support posts in your case are under the exact spots on the motherboard that they are needed?
Are you sure that there are no extra support posts under the motherboard shorting it out?
Are you sure that your power supply is powerful enough for your CPU, graphics card, and other components?
Are you sure of compatibility of all components?
List all of your components.

You have to be a little bit crazy to keep you from going insane.

SLP versions of Windows (pre-installed on retail computers) ARE keyed to hardware. The ONLY hardware that can't be changed is the motherboard. This is by Microsoft design. That is why you don't pay very much for the OS when buying an OEM computer. The OS is keyed to that computer.

Sometimes you CAN get an SLP version to work by installing the correct drivers after booting into Windows Safe Mode.

FYI, ALL versions of Windows since WinXP have some sort of keying to hardware. Even retail full versions. How you can migrate the OS to different hardware is determined by the version and by how forgiving MS is at the time. The EULA may state the OS can only be installed on ONE new computer but MS MAY allow you to migrate that OS to a new platform after it is removed from the original one.
