Question My GPU only works with AMD processor, not with Intel processor ?

Last week I bought an OLD PC and inside it had an AORUS MASTER RTX 3070, when I turned it on it works perfectly, and it is detected as it should be, this OLD PC has an AMD FX 2011, a MS-7641 motherboard VER 4.0, 4gb DDR3 RAM and a 650 PSU.
Ok now the problem is as follows, I want to test the GPU on MY PC which has intel i5-7400, Asus B250H motherboard, 16GB DDR4 RAM and a 850 PSU.

When installing it neither the Bios and windows dont recognize it, the fans off, only the lights its on. I also tried it on another computer with better specs, i9-12700K and the motherboard supports PCIE 4.0, but still not detected.
It only works on the OLD PC where it came installed. It was probably used for mining, but it looks so new and it shows little use. I already updated the bios of both motherboards, disable UEFI and enable CSM.

I also did benchmark tests in 3DMARK and it worked fine. I've tried many things but nothing works for me to make it work on other computers.
 
try reflashing gpu vbios, official vbios you can find here:
https://www.gigabyte.com/Graphics-Card/GV-N3070AORUS-M-8GD-rev-10-11/support#support-dl-bios

read notes before flashing
Hi kerberos_20 thx for responding me, well I try this to and when I use NVflash and change the VBios this error appear "pci subsystem id mismatch "
IDK how to upload a imagen here but on GPU-Z show me the GPU information and I notice the Device ID its diferent (10DE 2484- 4D50 4449),the first eight numbers are fine but 4D50 4449 is not similar to any other bios
RTX 3070 information from GPU-Z
GPU = GA104
REVISION = A1
BIOS VERSION = 94.04.3A.40.11
SUBVENDOR = UNKNOWN
DEVICE ID = 10DE 2484-4D50 4449
DRIVER VERSION = 31.0.15.1748(NVIDIA 517.48) DCH/WIN64
GPU CLOCK = 1500MHZ
MEMORY =1750MHZ
BOOST = 1845MHZ
 
that doesnt looks like original vBIOS at all, subvendor 4D50 is not gigabyte for sure, thats why it throws tantrum

your GPU has dual bios, you will need to flash both of them (if both have mining vBios) to gigabyte bioses
GPU has physical bios switch, you should switch bios when GPU is powered off, buf for flashing you can switch it directly without powering off
OC bios - L
silent bios - A
revision 1.x of board would be Fx bios (not F6x)
GV-N3070AORUS M-8GD_L/F2/0AF6 - OC bios F2

nvflash --protect off
nvflash -6 bios.rom
replace bios.rom with file name for that bios (Gigabyte.RTX3070.8192.210311_13.rom)

cant find A bios for silent mode on tech powerup database for 1.x board, but maybe it wasnt flashed and its kept original?
have you tested silent vbios first if its original?
