Installed new cpu fan, no display now

[m.moises122]

I just installed the Master Cooler Hyper 212 evo for my AMD 8350 fx CPU and the fans turn on, my peripherals don't light up and my monitor doesn't get a signal.

When I had taken off the stock cpu heatsink the cpu came off with it and some pins were bent, I was able to get them as straight as possible and the cpu locked in place with no problem.

When i turn on my computer the gpu fan, the psu, and the heatsink fan turn on but nothing else light's up. Normally the green light for the ethernet cord light up but this time nothing lights up.

It won't boot up if it doesn't detect the cpu. I would guess something is still wrong. Unmount the cooler and check your cpu pins again.

Do as Sedivy stated and ensure thermal paste is reapplied. Also, ensure that ALL and ANY PSU cables to the motherboard and any peripherals whether you disturbed/removed/disconnected them for the AIO install or not are and in-place and seated properly; CPU, 24-pin motherboard, GPU, etc.

EDIT: If you do have bent CPU pins, depending on which ones they are, different behavior(s) will occur with your system. There is no exact pattern to "pin" down so to speak. They can be bent pack into place, but extreme care must be given in doing so: https://www.youtube.com/watch?v=8i7u7niJjF4

You may be missing the 4/8 pin ATX power cable that goes into the board for CPU power. Either that or you need to take a zoom lens to your pins and make sure that when they are completely undamaged at the bases. They usually have small reinforcing rings of metal meant to keep them from breaking rather than bending, but a easy indicator of a dead chip is when the base of the pin is warped, tilted or doesn't line up with the others.

Make sure when you remove your IHS in the future, you slide it left to right on the thermal paste surface until it the solid paste cracks or soft liquid 'snaps' separate from the CPU... rather than pulling directly away from the board.

I reinstalled the cpu and heatsink all the pins are straight. The cpu falls right into place without any struggle. I checked all the cables on the motherboard and all of them are secure.
