OK so I've just built myself a pc. I have a ryzen5 3600x, aorus b450 motherboard, 16gb of corsair vengeance ram, dark rock 4 air cooler and a gigabyte rtx 2070 super gaming oc. My problem is when I play fortnite it crashes. This only happens with fortnite and ive tried a few different things but nothing works. The game plays for about 3-4 minutes and just crashes. Does anyone have any idea what the problem is or have a solution for it? Thanks.
