Yes, you can sell your old motherboard.

The only details linked to a specific motherboard are the Windows license (if valid), saved BIOS profiles (which can be removed via an update), and TPM keys for BitLocker encryption. The latter is lost during a CMOS reset or when swapping the CPU, especially if you don’t include the boot device. This information shouldn’t raise major red flags when selling. What worries me more is the errors during reset attempts, suggesting the board might be failing.
I wouldn’t believe the board is gone. Everything was running smoothly before I took it out. Someone mentioned I might have run into issues with sysprep because I wasn’t using safe mode. My Windows license comes from a retail purchase I made for that setup. I applied the product key on my new system.
