I have a pc from 2007, the issue is, the power LED is on, like normal, when the following cable is disconnected:
But, no GPU or BIOS VGA output.
When I connect it, the CPU fan spins, normally, but the power LED is not lightning up and still no GPU / BIOS VGA output..
How can I make the BIOS display anything on my monitor?
The motherboard model is GA-T671MG
I tried the power supply on another mobo and it works fine, I tried another power supply on this motherboard and still no video output.
I checked all cabled and I did a quick scan for scratches on the motherboard. everything looks fine.
No beep or any sound. Tried pluggin earphones into audio out and waiting for the windows sound to come. nothing.
