Acer Swift 3 sf315-52-58hg, problem with 1 core How can I fix this without changing parts?

cenity

Hello!
I have a problem with my laptop, programs often close without errors, there are blue screens and freezes when installing programs.
When checking the processor on a laptop with the S&M program, it gives errors.
threads 0: Cache 1 level - failed, Cache 2 level - failed, CPU ( integer) - passed, CPU (FPU) - failed, Power Supply - 3.
threads 1: Cache 1 level - 3, Cache 2 level - 4, CPU ( integer) - passed, CPU (FPU) - failed, Power Supply - failed.
Other threads(2, 3, 4, 5, 6, 7) all passed.
As I understand it, the 2 threads in the core number 1 failed.
How can I fix this without changing parts? I saw somehow you can disable 1 core in the processor, but my bios does not have such a function.
