I just upgraded my old Ryzen 3 to an R7 2700 paired with an RX 590 8GB (Gigabyte), the thing is when I want to play Fortnite my pc shuts down immediately, and I need to unplug the power cord and turn it on again, the pc couldn't even run fortnite for more than 2mins before shutting down, I checked my temps and they are normal (CPU around 40-50° and GPU 45-55°) so I thought it was a PSU issue, I played other games Borderlands 3, Shadow of the Tomb Raider (Everything on very high) for several minutes and nothing happened.



I checked my Fortnite game settings and DX12 beta was on, I thought that was the problem so I turned it off, I played for almost 2 hours and everything good, I thought that was the problem but yesterday I played fortnite for like an hour and it happened again, a hard shutdown.



I also use my pc to render with AutoCad, I have rendered 4 hours so far (heavy renders) with the cpu using 100% of its capacity at a regular temp of 60-65°. No shutdown whatsoever.



Any ideas on what could be the problem?
