Really frustrated over here and trying to get some help. I recently built a computer (1st time) for some gaming. I got it up an running (or so I thought), but when playing Fortnite, it will randomly (and without warning) completely shut down the entire computer. It doesn't happen immediately when launching Fortnite, and sometimes I've gotten through a few full games before it happens. No predictability to it.
I have tried updating all the drivers (NVIDIA, Bios, Windows, etc.) I can think of, and the problem still occurs. I know there are issues reported with the GeForce 30 series, but from what I've read they're not really with the FE ones, and its more of a crash-to-desktop issue than a complete shut down of the PC.
Any thoughts or similar experience help would be greatly appreciated!

Generally, computer rebooting randomly can be caused by many reasons, for example, overheating or a faulty power supply, a faulty RAM, driver problems, Windows update. As a precaution, I'd recommend reseating the RAM or testing it with one stick of RAM. It's possible that it could be your PSU, but with your PSU being 850W it has more than enough capacity. Is your PC just instantly turning off and then turning back on, or perhaps is the screen showing colors before it resets?
So, after visiting Microcenter Fairfax, and talking with the staff there (who were super helpful), we determined that it was probably a PSU issue. So I grabbed a 1000w platinum PSU and swapped it for the 850w I had in there. After a few days of playing, I haven't had any issues since. Going to keep an eye on it, but it seems to have solved the issue.I'm not certain whether I had a bad 850w PSU, or the 850 was just now powerful enough for the rig, but it was definitely an issue in the PSU realm.
So I am having similar issues as listed above, just replaced my RTX 2080 with a RTX 3090. Whenever I try to load into a game my PC shuts off and turns back on, I am assuming its my 5 year old PSUPC specs:i9 9900kRTX 3090Gigabyte Aorus Master z3901 WD 2 TB HDD, 1 WD 1 TB NVMe, 1 Samsung 256gb SSD4x G.Skill Trident Z RGB 8gb DDR4 3200ThermalTake Water 3.0 6 Total Case FansCorsair AX760 80+ Platinum certified PSU
