But what about an AI mouse?

Some motherboards did have overheating protection back then though. Personally I had my Athlon XP computer randomly shut down several times back then, because the system had some issue, where fans would randomly start slowing down and eventually completely stop. This then triggered overheat protection of the motherboard, which simply cut the power as soon as the temperature was too hight.

To shreds, you say?
