Games sometimes crashes for no reason what to do?

Some of my games sometimes crashed for no reason, sometimes not for a whole day and sometimes 4 times in 10 minutes totally random. I have a high end pc with a thick 360mm water cooling, I have an 850 watt power supply from Asus everything should work.

only some games crash, such as Rainbow Six Siege, Fortnite, Apex.

With gta 5, Valorant, minecraft, for example, this never happened to me

it would be nice if I could help myself

This can be anything from configuration incompatibilities, invalid drivers or compatibilities, hard disk defects to memory errors to CPU problems.
