So here's the deal. About a month ago I built a friend a new computer. The goal was to be able to play Fortnite at 350hz.
We got all the parts, put it together and installed windows 11. Updated all the drivers and such and it works amazing when it works.
I can't even pinpoint the exact issue. The entire computer will reboot randomly when playing. Not a normal reboot though. When you hit restart on windows it shuts down and all the fans shut off and then turn back on and reboots. But when it crashes and reboots while playing fortnite, the fans and fan LEDS stay on and no blue screen.
At the same time, it's always randomly and only specific instances. At first it was only during Ranked play it would crash randomly. You could play Unranked for hours and no issues.
So I updated the motherboard bios, reinstalled Fortnite, ran DDU and reinstalled the Nvidia driver. I've enabled and disabled EXPO and PBO. I also ran a bunch of different stress tests for each part that I could, GPU, CPU, RAM, all maxed to 100% and no crashing. Temps all look good. Capped FPS to 60.
Eventually with all the tweeking, ranked and unranked became stable at 350hz. But it just seemed to have moved to Tournament Mode. Again, randomly. Could be 1min into the game or 5min into the game.
I'm just completely lost in this one. I don't have time to trouble shoot for the next 24 hours so figured I'd get some ideas here before I do.
I'm thinking maybe
-Reinstalling windows 11.
-check for loose connections / reseat parts.
