damaged pins no discrete gpu lanes

My new motherboard worked well using the cpu graphics however I could not get anything from 3 different graphic cards. I changed power supply , memory as well but only onboard graphics worked. So I returned my new ( faulty) motherboard. The returns department of the vendor informed me I had bent some pins in the cpu socket. Not understanding the pin grid I am surprised everything worked except the discrete graphics card - using onboard I had no problem booting. Is this posible?

Yes. Modern GPUs integrate the northbridge, including the PCIE controller that is used for GPUs. That is, all the motherboard provides is power and physical lines leading to the connector. If you manage to bend a few pins that are supposed to pass through the PCIE signal for the GPU, then that's what's not going to work.

Thank you , as I haven't seen the damage I wondered which area based on the arrow mark I bent .top corner or what ? I don't ant to do it again . I thought it went in sweetly. I also thought the UK would not leave the EU or Trump become president.
