My computer starts crashing everytime i load B06

[BIGBOYAJ]

every single time i load cod it crashes as soon as i load into the game menu and i load the game in safe mode and it lowers all my settings and as soon as i turn them a little bit up it just crashes again, i have a  3060 12gb with an ryzen 9 3900x and 32 gb of ram. I think it has something to do with memory because when i turn on msi after burner and have the charts pulled up the memory it said i only have 2400mb of memory and ive been getting lower frames too for some reason
