Question Can't see mobo BIOS

[chillcat]

I bought a used RX 570 (Asus ROG Strix 4GB) many years ago, when I installed it, Device Manager would show Error 43 (no display from GPU), I installed Clock Patcher and it got fixed, but the problem, is that I can not see/enter the BIOS screen, I only see the display when it boots up to Windows. I just tried flashing a different VBIOS, still can't see/enter the BIOS (still seems to be running on clock patcher, GPU digital signature is unknown) is there any other solution? Thanks

Edit: I am using a HDMI cable, when I try to use a DP cable, no signal D:

Here are the specs:
CPU: i5-2310
MOBO: ASRock H61M-VS
RAM: 8GB (2x4)
SSD: 240GB WD GREEN SATA
GPU: ASUS ROG STRIX RX 570 4GB (Device ID: 1002 67DF - 1043 04C2)

If you see Error 43 in Device Manager and 0(zero's) in GPU-Z, then you GPU is as good as gone. You forgot to mention the make and model of the PSU and it's age.

Error 43 is fixed when Clock Patcher is installed, but because of Clock Patcher, I can't see the BIOS. What do you mean by 0's in GPU-Z?
