GPU not detected on cold boot

[Sancuss]

Hi guys, I am facing a strange problem since few days which I needed help with.

 

 

Whenever I cold boot the PC my GPU is not getting detected by the PC and hence, I am not getting any display at all. Not even the bios flash screen is being displayed.The strange thing is if I restart the PC then I get the same issue of GPU not getting detected and not getting any display. But if I switch off the PC using power button then power on the PC again the GPU gets detected and I get display as well. And now the PC works like nothing has ever happened. But this problem persists if I switch off the PC and start it again on a cold boot after 20-25 mins.

To troubleshoot I tried the basic steps

• Tried running the system on 1 ram stick, interchanging stick/slots. Issue not fixed
• Uninstalling the GPU from device manager, using DDU to remove drivers and fresh install Nvidia drivers. Issue still there.
• Resetting the BIOS to factory settings
• Testing separate displays, issue still there.

Now I am very confused as to what the faulty component is/what the issue is. If the GPU is faulty then why does it give display after tuning off the PC & again starting it? If its not the GPU then why does it not get detected during the cold boot?

 

Could the Motherboard PCI slot be faulty? I have recently bought a new PSU a month ago so I don’t think the PSU is at fault.

Have u tried to use different cable? Had similar issues years ago whit new amd gpu(rx 460), didn't know why it happened, tried everything, nothing worked, digged deeper in the web and found out that this may be just a cable problem.
