A good place to start is to monitor temps and stress test your cpu and gpu as well as running Memtest to check your ram. If all is fine and you’re still getting restarts, my money would be on a failing PSU. Have you added anything to your build recently?

I alredy did that, restarting CMOS by open up the battery, the build is about 6 7 years old,
Maybe is the pcu cooler, maybe is qyality of thermal paste, maybe to old PSU.... Aaaaahhh everything daaamn old pc!
