Sapphire Vega 56 Pulse 8GB

Didnt use DDU so that might have caused it on old system. New OS runs on fresh AMD drivers. It could be related to game itself because card works literally flawless in Dx11. I am just concerned it might be something hardware related I use 2 cables, each power one 8pin socket. Ive seen opinion that it could be caused by Windows version and SoTR. Many people on v.1709 had problems with it with same NO SIGNAL problems.

Hey! Last Saturday I bought a brand new Sapphire Vega 56 Pulse 8GB graphics card. After installing it I ran into a problem - sometimes (every 2-3rd time), when Windows was loading, my screen would go completely black and monitor shows NO SIGNAL, and in the same moment, my GPU fans go crazy, (spinning at 100%). I couldnt do anything but restart my PC using a button on the case. I thought it was related to my Windows being old and neglected already (havent reinstalled system for like 4 years, didnt properly erase AMD drivers before installing the card), so I decided to fully reinstall Windows (I did a full format:c), reinstalled Windows, installed new AMD drivers, everything was fine for five days, I played Metro Exodus and Wreckfest for many hours and it was ok, card was behaving very good, low temps, low power usage. Today I bought Shadow of the Tomb Raider on Steam. I downloaded the game, set some settings, press Play... and same thing happens - fans go 100%, monitor shows NO SIGNAL. It's like that on both 60 Hz, 75 Hz (I have FreeSync 2560x1080 display), fullscreen, borderless, min settings, max settings... I managed to find the cause though - when I unticked "Use DirectX12" in SoTR options, game starts without any problems. I have tested it for 4 hours and it works flawless. But Metro Exodus also uses DX12 and it works just fine! What can I do to prevent this thing from happening again? Why does my card behave like that? Is it faulty, should I return it? Why does it show "NO SIGNAL" and why do fans go 100%? My specs: i5 6500, Z170K motherboard, 4x4 GB RAM, 650W EVGA PSU Card works just fine when in game besides that, 180W max power draw, max temp 70*C, good framerates, Ive been testing it for like 20 hrs in Metro Exodus, Wreckfest and SoTR (without DX12 of course lol). I am just VERY concerned about that crashes. I can understand that on previous Windows it could be messy driver or something but these crashes on new OS with Dx12 enabled really concern me. I still have 5 days to give it back but I dont know if I should, maybe its just driver related or something... Please help Links To
