So when I play Witcher 3, elden ring or any other heavy game, after a minute my NVMe ssd dissappears and whole pc becomes very laggy and then just crashes, but after restart everything comes back to normal. I ran ssd health check and everything shows normal. I also tried installing a game on another ssd, then that ssd disappears. I tried switching ssd places that didn't help. Tried switching to windows 11, tried undervolting gpu. It might be a motherboard or a power problem, but don't know how to check that. Also my pc is 2 years old.
