That’s interesting. I would have guessed something like an unsigned driver or malware. I don’t think just one device change would be enough to cause a reactivation, but maybe repeated ones. I’ve changed CPU, GPU, optical drives, RAM on a system with no reactivation. Motherboard seems more likely to trigger it, but that doesn’t seem likely in this case. More info would help, but in the meantime OP should scan for malware with RogueKiller or at least ADW Cleaner/Malwarebytes/ESET or another decent alternative.
