My computer Crashes after I installed my GPU
So, on Christmas I received a new GPU the Radeon sapphire pulse Rx 590 8GB. I followed your upgrade guide and bought the correct adapters for the GPU and PSU since I wanted to supply enough power for the card. All started well with my computer turning on and booting correctly, until I started playing a game (Dawn of war Soulstorm) which is not very demanding, and about 15 minutes in my screen froze and the sound continued. I tried to alt-tab and Crtl-Alt-Del with no success the only solution was to turn my computer on and off again and let it boot. I thought maybe it was my drivers, installation, voltage, etc with nothing working except for underclocking my GPU and majorly pumping up my fan speed. This worked and is still working but I want to figure out why it is still crashing when my voltage is at 0 not -5. I have put my GPU in my grandpa's gaming rig and it works great with normal; temps and extra smooth performance. I placed his RX 570 8GB into my PC and had the same issue
My Pc Specs

I have put my GPU in my grandpa's gaming rig and it works great with normal; temps and extra smooth performance. I placed his RX 570 8GB into my PC and had the same issue where it would crash. I tried multiple games on higher and higher graphic settings and found stable and great performance on his pc on default settings; while mine was barely holding on with higher cooling. I switched PSU to check if that would work and no change so it is not the PSU, cooling, and I have tried different PCIE 16x slots to no avail.
What is the issue? Thanks.
