Whenever I play a game, mostly fortnite but it happens with all the other games too, I can play for 10-15 minutes adn then the game crashes to desktop. I am 99 percent sure it is not the graphics card because it had been happening to my old 1070 and then I upgraded to a 2070 super and it is still happening. Could it be a psu problem? my specs are gigabyte x-370 motherboard, ryzen 7 2700x. 16gb ddr4 3200, EVGA rtx 2070 super, Corsair mx 650. My temps are fine when it is happening but I noticed that it says that the memory usage goes to 100 percent right before it crashes. any ideas on how to fix this?
