Just built a new PC, which component has gone bad here?

I used to build custom gaming PCs regularly, but hadn't attempted in in over a year due to some crap going on in my life.

I built one today, and as expected, there is an issue. While seating the processor on the motherboard, there was low lighting in the room and it automatically slid a bit to the side before it got locked in place (which may have damaged the pins). It's AMD FX 8350.

After that, I put everything else in place, turn on the power, see all those cool LEDs, and see no display! On closer observation, I noticed the following: The fans in the PC case, the processor heatsink fan, and the power supply fan, are all spinning. The LED on my graphics card lights up (It's an XFX Radeon RX 480), but the fans on it don't spin. I initially thought this meant a faulty GPU, but then realised some current GPU fans do NOT spin unless they are under heavy load. I don't know if my card is designed that way (couldn't find related info anywhere).

I checked all the connectors (including the 8pin connector of my GPU), and they are fine. My motherboard doesn't have onboard graphics to test, and I don't have access to another PC to test my GPU.

So now, it means one of these things could have happened:-

1) I ruined the pins on my CPU (in which case I can't claim warranty, and have to shell out for a new CPU)
2) The graphics card is faulty (I can get a replacement)
3) I have missed some small connection somewhere (highly unlikely).

Which of these is most likely? Also, does a ruined CPU mean no display at all, not even the BIOS or the initial POST screens? My monitor is working fine though, I tested it with my laptop.
 
Solution
After working through the link provided by clarkjd, If you still have issues, I would take out the cpu and visually inspect if thre are any bent or broken pins. If they are bent you can try bending them in the right position with sth like a straight razor. If some pins are missing (broken) then most likely you will need a another cpu.

I guess so. I should never again go for motherboards with no on-board graphics. It gets impossible to test the components since I have no access to spares.

Great, this fixed it! Some pins were bent on the CPU socket on the motherboard. Just straightened them out with a pair of tweezers, now the system boots up.
