Computer freezes under load. Kernel-power error 41(63) What should I do?

Question

Iron

Good day! Help out!
Configuration
Proc. amd fx 8350
Motherboard Gigabyte GA-970A-DS3P
Video adapter AMD Radeon R9 270x Series (2 GB)
RAM 12 GB
Power supply 750W
Windows 10
The computer has been freezing for several months now. Hangs only under load (in games), not immediately after an hour, sometimes 2 games. Just the sound of "tsyk" from the system unit and the picture becomes tightly, sometimes even the sound in the speakers freezes.
In the event log, always Error Kernel-power 41 (63), googled, asked friends and here's what I tried:
1. I disassembled and reassembled everything.
2. I stuck one stick of RAM.
3. Reinstalled Windows 10 (many times)
4. Tested computer AIDA 64 (I am attaching a picture, the question is whether everything is fine with the food of the processor ????? )
5. I pulled out the battery from the BIOS (although I never touched anything there)
6. A bunch of little things from different advisers The

computer worked in this configuration for about 4-5 years and did not know any problems. I don’t know if this is related or not, but not long before the sad events, an SSD Disk Drive TOSHIBA-TR200 (SATA-III) was purchased, which is now a system drive and is paired with a Disk Drive ST3500418AS (500 GB, 7200 RPM, SATA -II).
Guys help out, PLEASE, since I only play online games, my nerves no longer take out these freezes ... Since the budget is limited, I can’t just buy and change spare parts until I’m lucky, and in general this may not solve the problem ... Help, I believe in you!

Answer 1

change/repair the power supply.
the supply voltages sagged under load, they sag even more, the computer goes crazy.

Answer 2

Yes, you fry the processor mercilessly!
The recommended temperature is about 66 degrees for the FX series, and yours is under 78.
Look at what you have with cooling, clean the radiator, change the thermal paste, it has lost its properties in 5 years.
AMD FX has trouble with temperatures, there is no exact data on degrees, in the AMD OverDrive program you can see the Thermal margin parameter, this is the remaining margin before the overheating point.
PS
don’t pay attention to voltages, the drawdown is insignificant, only 1.7%, this is within the measurement error.

Answer 3

Also pay attention to the video card: the temperature is 83 gr. and the fan to full (no applications using it are visible).
