Situation
When playing Fortnite for about 10 minutes or less, my PC will shut off instantly (without a BSOD) and restart itself.No other games are causing this issue. I reviewed the Event Viewer and the System log shows that a Kernel-Power, Event ID: 41, Task Category: (63) event has occurred. I have also disabled "Automatically restart" within Startup and Recovery in the Control Panel but no BSOD shows up.
PC Specifications
I built the PC myself about 2.5 years ago with the following components. I am running Windows 10.
CPU: i5-6500 3.2 GHz Quad Core
MOBO: Gigabyte GA-B150M-D3H-CF
GPU: MSI Radeon RX 480 (8GB)
PSU: EVGA SuperNova G2 550W 80+
RAM: Corsair Vengeance LPX (2x8GB) DDR4-2400
SSD: Samsung 850 EVO-Series (250GB)
Stock coolers only.
Attempted Solutions/Tests (in order)
(1) Failing PSU: Initially I thought the PSU was failing based on other threads from here, Reddit and other websites. I was able to use my EVGA warranty and obtained another PSU (of the exact same model) but the restarts continue.
(2) Resetting my PC: I uninstalled Fortnite and GPU drivers prior to wiping my computer which did not solve my problem. I did a reset of my PC (keep my files) and this actually stopped the crashing and restarts for about two weeks. I had no issues playing Fortnite until yesterday, when the restarts began again.
(3) Updating the BIOS: I went to the Gigabyte website and found the latest BIOS firmware for my MOBO. I updated from F16 to F24. No success with this either.
(4) Stress testing (and HW Monitor):
I downloaded Primer95 and Furmark to stress test my PC. I ran the Prime95 Smallest FFT Torture Test for ~8.5 hours and the CPU temperatures did not exceed 50 Celsius and the PC did not crash or restart overnight.
In the morning, I ran the Smallest FFT together with Furmark for 30 minutes, which induces a greater demand over a long period of time than Fortnite would (before crashing which again is ~10 minutes). The maximum GPU temperature was 75 Celsius and the CPU again remained under 50 Celsius throughout the 30 minute test. Surprisingly my PC did not crash and restart under the very high demands of the tests.
I ran the Windows Memory Diagnostic Tool and it shows no problems with my RAM. I feel that my issue is not likely to be caused by RAM.
HW Monitor is running while Fortnite is running, and it does not show any abnormally high temperatures and shows that all the fans are spinning. It also shows 100% CPU utilization and all 4 cores running at maximum.
(5) Miscellaneous: I cleaned out the dust in my PC using compressed air. I also moved my PC to a more open location and plugged it into a different outlet. No luck with any of these.
Closing
Any and all advice and suggestions are welcome. I am opening to trying any new solutions. I am pretty frustrated with this issue and I am not sure where to go from here. I am open to buying new PC components but would like to narrow down the cause and prefer not to upgrade everything. Thanks.
EDIT: I tried running two other games: Arkham Knight and The Witcher 3 (two older games that I can run on high graphics with steady FPS) and the crash and restart now occur when playing them too.
