Please i really need some help..

I just don’t know what else should i do. I tried so many fixes but none worked. SO while i m playing randomly it freezes and then i get crash, is so annoying. If you think is the ram i don’t think so i have 6gb ram and while i m playing rust it s just at 40-50 % usage. I really would appreciate if anyone can help me with error.
