Hello everyone. I recently bought a new XFX AMD Radeon RX 5600 XT THICC III Ultra and replaced my old r9 380 today. At first, there was no issue, Windows booted properly, I have checked the AMD software and device manager, and everything seemed in order. So, I started to play Witcher 3 to test it, FPS was normal (80-100) but there was stutter. After 3-5 minutes of playtime, the computer crashed to black screen and wouldn't boot after restart (it powers up but all I see is black screen, no BIOS or anything). I've tried to boot with my r9 380 to see if I mess something else but it runs just as fine before. I've tried factory reset with adrenaline software, installed the new GPU and booted again but the result was black screen. I have used DDU to completely remove the drivers in safe mode with my old r9 380 on, selected the option "clean and shutdown". After shutdown, I installed the 5600 xt and tried to boot, did not work again. Am I doing something wrong, or do I have a faulty GPU?
