|You can install a different motherboard in your PC. The question is: will the PC boot with the OEM version of Windows. The answer to that question is maybe. As you probably suspect, the limited OEM copy of Windows is keyed to that HP model and some others. Some users have had good luck doing this, others, not so good.|
If attempting your best chance is to match the boards up for chip sets and other features.
How do you know for sure the motherboard is dead? What caused it to get dead? If an electrical event, the power supply board may both be gone.
