Question New computer build, crashes while playing Fortnite

[JayferX]

I built a new pc the first of the year. It ran fine for a couple of weeks but now I am getting blue screens / restarts when my computer is gaming. This seems to only happen under heavier loads, like playing Fortnite. I can run my computer all day or play something like Civ VI and I don't have any issues but as soon as you load up Fortnite it will sometimes crash during the loading screen.

My build is:
Ryzen 7 2700 - stock cooler AMD Wraith Spire, from what I can tell this is ok, CPU not overclocked
MSI B450 Tomahawk
16GB DDR4-3000 Corsair Memory (CMK16GX4M2B3000C15)
XFX Radeon RX 580 (previously had MSI GTX 970, same problem)
1TB SSD
2TB Hard Drive
EVGA Supernova G2 550W Modular Power Supply


I traded my video card out thinking that may be the problem. I was running a nVidia GTX 970 but the new Radeon card is doing the same thing.


So far I have:
-exchanged motherboard for a new board
-entered CAS, timing and voltage for RAM in the BIOS / I have tried all different kinds of settings and the system still crashes
-ran two sweeps of MemTest and system tested good, I also tried one ram stick in at a time and the game still crashed
-updated BIOS to latest version - 7C02v17 (3/6/19)
-updated all drivers using Driver Booster 6
-ran Prime95 and heated my cpu up to 85c for 5-10mins and the system was stable
-switched Corsair RAM out for 16GB Corsair DDR4-2400, (CMK16GX4M2A2400C14) same issue
-switched back in Geforce GTX970 card, still crashing

Looking for any suggestions on things I could try.
Thanks in advance!

So, I find a couple of ways you can be running the memory:
CMK16GX4M2B3000C15
15-17-17-35@1.35V, 3000MHz
and
15-15-15-36@1.2V, 2133MHz
or
CMK16GX4M2A2400C14
14-16-16-31@ 1.2V, 2400MHz
and
15-15-15-36@ 1.2V, 2133MHz
I take it that you are running one of the above configurations?

Also, you didn't spec your PSU.
You probably should.

Did you use a new PSU, or re-use a PSU from a previous build (not all that uncommon a practice)?

Yes, I have tried 15-17-17-36@1.35v 3000mhz. Someone had mentioned that the board only supports the ram at 2933, so I had tried that as well. The MSI board also has A-XMP Profiles 1 and 2 @ 2800 and 2933, I have tried both of those on default and same thing with the crashes. The A-XMP Profiles also changed with the latest BIOS update but all the configurations crashed with the last BIOS and the current.

Power Supply is an EVGA Supernova G2 550 Gold Modular. It was recycled from my last build from winter 2017, so about 1.5 years old.
