So basically the other day i was playing games just fine but this morning, while i was in the middle of playing a game, it crashed, i couldnt reload the game bc it gave me an error code and the bsod on me. Stop code memory manegment. Now, every game i tried to play i crash either while joining a server or in the middleof the game, i cant last 5 min. I tried running memory diagnostic tool and everything seemed fine, i updated my drivers and i just dont know whats wrong. Discord also randomally crashes and also, i cant update windows bc that too gives me a bsod. I really dont know what to do or what to replace. Any help???? Please and thank you.
