There is an AMD Athlon II X3 460 processor. In fact, it has 4 cores, that is, in the factory configuration, the last core was disabled due to poor performance.
At maximum load on the cores, nothing happens, and crackling sound and a blue screen. That is, the absolute departure of the graphics driver. I think this can be removed by lowering the frequency or voltage on the core.
Question 1. How to determine the core on which you need to perform such manipulations?
Question 1. Can this be done without intervention in the BIOS?

disabled due to poor performance.

Or just like that, at the behest of marketing.
A certain percentage of crystals successfully unlock the extra core and work stably.
Do you have active core 4? So turn it off. This is driven in the BIOS (I don’t remember exactly how years ago)
If it’s inactive, then why did you decide that the problem is in the processor? And not, for example, in memory?

A large load can lead to overheating and to a deterioration in power quality ...

+ only on one core out of 3x (4x) it is impossible to lower the frequency in principle

Firstly, you need to check all PC components for serviceability:
HDD -> memory -> Power supply.
Then check the temperature of the system for overheating
. Then run the processor first in applications using one core and then two / three. If errors are detected on the multi-core test, disable the third core in the BIOS.
I can’t guarantee that exactly the same core will turn off (on which we can possibly identify a malfunction), but it’s worth a try
