Computer won’t boot after changing motherboard
This is a common problem and there are many solutions depending on the Operating System. Before I get into the solution let me explain a little about why this happens.
This happens because the IDE or SATA drivers (basically the Hard Drive Controllers) are not loaded for the new motherboard. During the boot process windows loads the Hard Drive drivers first then uses that interface to access the HDD. When you change motherboards the drivers are not already there and so Windows will not boot. Sometimes you do not run into this problem when changing mother boards because Windows already has the drivers for that motherboard. This problem occurs most of the time when installing a new motherboard.
Note-Check with Microsoft to ensure your version of Windows can be moved to another motherboard. Following these steps may get you computer to boot but you may not have a validly licensed copy of Windows

Computer won’t boot after changing motherboard – Computer Does Not Boot Any OS
Since Windows XP is taken care of in the above post, Windows Vista and 7 are next. If you have Vista, my first recommendation is to simply buy a computer with windows 7 and install a fresh copy of Windows 7 Vista is a bad OS. However, if you have to keep using Vista these steps will work.
Take the Hard Drive and plug it into an old computer. Usually Windows 7 and Vista will have drivers for old computers and windows will boot. Then follow the instructions as if your computer booted.
