Computer freezes up. How to decide?

Question

Iron

The computer began to freeze frequently. If there was sound in the headphones, then when it freezes, such a "trrrrr" appears instead. I sinned on the PSU and HDD, changed everything, updated the BIOS, all the drivers, etc., but the freezes remained. It freezes mainly in games and programs such as: Chrome, Adobe XD, Opera, Skype. The most interesting thing is that if there was no freeze during the loading of the game, then you can play quietly for an unlimited amount of time, until the first exit to the desktop. I also noticed that when the game is minimized, the computer starts to slow down a bit and after 2-3 minutes it also freezes. Help, already exhausted :)
Characteristics: i3-2100, P8H-67M LX board, 4GB Kingston 1333mHz, 2GB Kingston 1333mHz, Aerocool VX-400 PSU, HDD Seagate SV35 1TB.
I also went through the RAM with Memtest. Two full passes, no errors. Could this be due to failures in the SATA 3/6 GB/s connectors? Capacitors are fine. The processor temperature does not rise above 40C.

Answer 1

Computer freezes up. How to decide?

There are two ways to solve it
- 1) Make a diagnosis, establish the exact cause of the freeze and eliminate it.
2) Try to guess yourself, or turn to a fortuneteller. This method does not involve diagnostics. Pure magic and luck.
You clearly chose the second option. Only the resource was mistaken.
I can recommend a resource where fortune-tellers and psychics gather.

Answer 2

Ok, changed hdd and power supply.
Install the coreTemp program. check the temperature of the processor in operation. Overheating can cause throttling.
Check the computer memory with the memtest program (it is highly desirable from a bootable USB flash drive).

Answer 3

Check video card and RAM

Answer 4

Memory. Check the memory - take it out, wipe the contacts (this simple advice often solves the problem), rearrange the modules in some places, try to start on half the memory ... There may also be a glitch in the video memory - I had this when the repairmen burned my vidyukha, hitting the power wire with a perforator :D

Answer 5

Cut down through the button (or through the socket) and run in safe mode. Remove programs that are not needed. Also remove antiviruses (so that 1 remains). And you will not hang anything.

Answer 6

The first one is capacitors.
Then the temperature under load.
Start diagnosing from the bottom. From the motherboard.
