The pins are on the CPU socket not the CPU but they are still very delicate.
I'd take the motherboard out of the case, stip it down and re-build it on a bench/table making sure the CPU is correctly installed, the RAM is properly seated and all the connections are tight. Make sure the 24 pin ATX connector and the 8 pin ATX aux power connector are attached.
