Motherboard Giigabyte z 370m d3h

Supply Aerocool HIGGS 750W
Windows 10 64 1903
Freezes the computer in games at maximum settings, and sound loops (tr-tr-tr-tr-tr). I have to restart the computer by clicking the Power button. Wattman is reset to default after reboot.
I tested the video card in a load of 30 minutes in Aida 64 through a line of 12 volt-11.880 +
RAM checked memtest, no errors.
Games hang after 10 minutes or an hour. If I set the vertical synchronization and the limit of 60 fps, then hangs can occur after 1, 2 hours.
CPU temperatures are at most 65, and video cards are 70-80!
I did not buy the video card in order to have an intimate connection with the hardware, but to enjoy games with high settings.
Nothing clocked. Motherboard bios last. Drivers are latest.
What should I do with this piece of iron?
