Could be a faulty CPU thermal sensor for the BD PROCHOT thing; it might be dedicated, so while windows might report otherwise, BD PROCHOT could be getting different signals, and cause throttling to occur.... doesn't look like you can reinstall it, or just delete it or anything....
If it is from windows, you can delete it, then run SFC (system file checker) to re-download it.
Only REAL fix looks like the one your currently using....
