Check that the processor and graphics temperatures are good, although you have replaced the paste, maybe the cooling does not work well

First, observe whether it shuts down on exact 15 minutes every time. Can you switch it on instantly after shutdown and runs again for 15 mins??

If it shuts down in exact time every time, then very likely its a bios issue. You need to clean me region in bios. This mb is known to have me region issue.

no after firt power off if i poweron again, shitdown very quickly.I tried to blow with cold air and it works properly, as soon as I stop blowing cold air goes out. I noticed that the fan runs correctly and slowly but before switching off it starts at maximum speed for a second and then turns it off.
