I just bought a second hand GPU and I place it in my pc which was still working and it won't show anything on my monitor but the GPU fans and led still working and the HDMI cable was plugged into the GPU not motherboard and I tried switching to another motherboard but it's the same it won't show signal to the monitor and it boots perfectly without the GPU and I suspect that the GPU bios was modded but still no proof anyone knows what's going on?
My specs:
I5 8400
H310m - DVI
T force 2666mhz 16gb ram
1070 MSI aero 8gb oc
