Hi, I have just bought a RX 5600 XT and after a few issues with screen freezing after kernel starts loading, resolved by compiling EFIFB (no previous FB compiled in) the card has been working fine for 2 days booting normally. The machine then started not to boot, not even to get to BIOS (so you couldn't even press DEL to get to BIOS screen). I took the card out and replaced with old card and PC started fine. I tried this 4 times and still with new card PC would not even POST. I don't have a little speaker to here if there are any beeps.
I am returning the card as it feels like that is the problem but have a nagging suspicion this could be some other problem like power supply. I have 700W coolermaster PSU which should be ample (according to websites) but is 9 years (amazingly they had the foresight to provide 8 and 6 pin cables which were both plugged in). My next issue is do I get another 5600 XT (different brand) or are nvidia equivalent better? I have always been an AMD fan. Could I end up in the same boat. PC spec - ASUS 470 Pro MB with 2700 Ryzen. Any advice would be much appreciated? John
