Asus B550 Strixx Gaming Wifi II board and Asus 3060 OC GPU problem. Bios keeps giving me a no supported GPU UEFI so CSM will be enabled. I flashed the latest bios and for a minute looked fill screen and working. 3 days after building today, startup causes 4 beeps error but still loads windows. The problem is disabling CSM causes the error and BIOS looks smaller with black boarders on sides. After error occurs, can't go into bios with CSM disabled. Any thoughts?
