BSOD playing Shadow of the Tomb Raider, and more games.

Hi!, I recently bought a new pc, these are the specs:
- Motherboard: MSI B450M Gaming Plus
- CPU:Procesador AMD Ryzen 5 2600X 4.2 Ghz
- GPU:Sapphire Nitro+ Radeon RX 590 8GB GDDR5 UEFI
- RAM: HyperX Predator HX430C15PB3K2/16 - Kit de 16 GB (2 x 8 GB) 3000 MHz DDR4 CL15 DIMM
- SSD: Samsung SSD 970 EVO NVMe M.2 250 GB
- HDD: Seagate Barracuda ST1000DM003
- PSU: Cooler Master MWE Bronze 550 550W 80 Plus Bronze
- Case: NZXT H500i
- 2 Aerocool Fans P7-F12
I built it myself (not the first time), but I started getting BSOD (I supose it is, because my games just freeze and then I get a black screen, then, the pc restarts), I read the .dmp located in System32/Minidump with BlueScreenView, WhoCrashed, and they show atikmdag.sys as the cause of the restart/error/BSOD, so, I used DDU to unistall all the drivers, did a clean install (version: 18.12.2, also tried 18.12.3 which is optional), tried oldest versions like 18.8.1 that comes with GPU's CD, but the restart just happened again, its weird, depending on the driver version, some games freeze and restart, and others don't. It restart with fortnite (oldest version), but worked fine with BTF3, Shadow of the Tomb Raider, Dota 2, but fortnite works fine in latest version, and the other games mentioned, don't, so, I don't know what to do.
I reinstalled the O.S. as well. I tried MemTest86 and after 3 hours of test, it didn't show an error. Also Prime95, with my CPU at 3.8Ghz, 5min, 3 of them, with my CPU at 74° celsius, also FurMark, 18 min of stress test, my GPU gets 72°-74° celsius, and it didn't crash or anything like that. Also 3DMark and it didn't crash. Went in UserBenchmark and I got this results:
PC Performing as expected (58th percentile).
UserBenchmarks: Game 77%, Desk 67%, Work 69%
CPU: AMD Ryzen 5 2600X - 95.1%
GPU: AMD RX 590 - 80.7%
SSD: Samsung 970 Evo NVMe PCIe M.2 250GB - 228.6%
HDD: Seagate Barracuda 7200.14 1TB - 65.8%
RAM: Kingston HyperX DDR4 3000 C15 2x8GB - 104.5%
So, that's it, I hope I can find a solution right here, thanks in advance.
PS: Sorry for bad english.

Hello SpeekDXG and welcome to the forum!

It does look as if the graphics driver is responsible but I see that you have already explored this route quite thoroughly and tried a range of drivers.

It could be that the graphics card itself is faulty and so if you can swap it or remove and test with the onboard graphics that would be my next step.

A couple of other things to note:

You have not successfully activated W10 yet - it has failed.

The memory test you ran needs to be done for a minimum of 8 passes.

Hello!, thank you!, yeah, I didn't activate it because I was just trying if the O.S. reinstall could work.
I'm going to try 8 passes now. I talked to the site were I bought the components, and they said that it is propably the GPU itself, as you said, so, I will probably send it them, so they can check it. Hopefully it will be only the GPU that has the problem.
I will update this when I have my GPU back. Thanks.
