Restating PC / mobo the problem

[Hypnos600bc]

Hi guys! I'm having some problems with my PC, every day it's restarting itself at random events times. The only way I could make it work was by pressing into the cooler of the processor and the PC would have hit it off. But now nothing works, I've stripped the CPU cooler to see what's the problem and can't find anything wrong. Here I've attached a video 

My PC configuration is Asus z77 Deluxe Intel 3770k with Nvidia 770gtx.

"Hit it off"? What do you mean by this?

It means that the PC would start normally

If you had to push down on your cooler/processor, the first thing I would check is making sure your cpu pins are fine and that it's seated properly. Make sure when you remount your cooler that you double check the directions and apply adequate mounting force but don't overdo it.

Ok, so after some time I've checked everything and the problem seems to be my ram memory. I don't know if it's because of a bad position on the slot or maybe some faulty ram, but if I move it the PC works
