I cannot be more specific than this but:

All motherboards run on a low-level system controller/manager called the bios - the bios (depending on design) may or may not include pre-settable warnings about detected impending hw disasters .................. stuff like overheating CPUs, fans that stopped running or that are running slower than the design speed etc etc etc ........................ and the alarm is generated via an on-board speaker or buzzer.

In your case (since the problem manifests during rendering operations) I think the  problem somehow relates to the CPU overheating (or then crossing the temp alarming set-point) for some reason

Simple solution often is the removal of dust etc from inside the machine (using compressor with a controllable air jet to blow all the rubbish out the case and off all surfaces - imo a vacuum cleaner is mostly a waste of time).

IMO its NOT Studio or Pinnacle specific - ANY app that will tax the CPU to the same extent is going to cause the same misery
