I've had this new pc for two months now, but only played really non-demanding games like League of Legends. Recently tried playing Cyberpunk 2077, Path of Exile and Horizon Zero Dawn and they always crash, after around 30minutes of gameplay. I have the latest bios and nvidia drivers. Temps stay pretty safe all the time, the gpu (Rtx 3080 Galax) stays at 65c and cpu (Ryzen 5600x) at 60. I have no idea what may be causing it. My PSU is 800w so I think that should be safe. I have tried my RAM both with d.o.c.p. on and off and the same happens anyways.
