For 2 days my computer has been freezing, restarting itself, games freezing and suddenly closing. I decided to do a system stability test. Yesterday it was giving a hardware failure message. It didn't give it today but in the tests I did today I saw that the CPU throttling was 31% and the processor cores reached 100 degrees. Also the processor reached a maximum of 88 degrees. What is the explanation for this and what do you think I should do?
