When I power on or restart the system, the BIOS has 5 long beeps, monitor display nothing (neither Asrock logo non loading spinner) until it show Windows login screen. Checked the device manager the GPU driver is there.

If unplug the GPU and connect monitor to onboard HDMI, the system will startup normally without beep.

The long 5 beeps is warning of missing graphic card. Primary GPU in BIOS is set to Auto. The GPU has been tested on old system is working fine.

My system spec as below:
Asrock B560M Pro4
Intel Core i5-11400
Team 16GB DDR4-3200 RAM
Galax GTX1070 8GB GPU


May I know what is the cause, or any driver will cause the BIOS failed to detect the GPU? But still able to show display after Windows load? ]]> Wed, 17 Nov 2021 21:26:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=19835&PID=91005&title=cannot-detect-gpu-before-load-into-windows#91005
