Is it possible to damage CPU pins on the motherboard so that only PCI-e 1 doesn't work? (PCI-e 2 works fine) I swapped CPU on my motherboard and my GPU doesn't show a picture in PCI-e 1, it works fine in PCI-e 2. Also, motherboards hdmi works fine. So I RMA'd my motherboard. I got reply that they have declined because CPU pins are damaged. But there was nothing wrong with the motherboard aside from PCI-e 1 not working. Is it possible that I damaged CPU pins that only one PCI-e slot doesn't work?
