PC Wont Post, GPU fans twitch every 5 seconds

[zachwest23]

So basically i let my friend borrow my CPU cooler for a little and when he returned it and I reinstalled it my PC wouldnt post. I think it was on really tight so I reinstalled it again properly and it still wont post. What happens is I get ZERO error lights on my MoBo, my GPUs fans twitch every 5 or 6 seconds, and all the fans spin fine aside from the GPU. I have tried a seperate PSU just incase it was dead to no avail. I believe it is bent CPU socket pins, but Im not sure. I've tried reinstalling my CPU tons of times and still to no avail. Anyone else ever have a similar problem who can help me? All wires are secure and UNCHANGED prior to the problem. No post to the MoBo onboard graphics either unfourtunately. Thanks all for reading.

Have a close look at the motherboard pins. Some might be bent. Post a photo if possible.
