Hello,

I've recently upgraded several of my components. In fact, I ended up keeping just the motherboard, a hdd and some fans.
Now I tried starting up the PC but got no screen, which in and of itself is not the most unique issues.
I put back the old CPU and updated the BIOS from p2.0 to p7.0 to p7.2.

I put in the new CPU but still got no screen.
Ive noticed that the USB devices don't get powered either, which leaves me to think its a problem with my cpu or its compatibility with the motherboard.
I had some trouble initially putting in the CPU (it was not sliding in as well), but eventually it did. I believe that one or more pins are bent. I'm thinking this might be the problem, but before I spend more money on a new cpu I was hoping someone might offer another possible reason.

I've already tried:
  • CMOS battery reset
  • Switching from GPU to motherboard
  • Removing one of the RAM strips
Specs:
CPU: AMD ryzen 7 5800x 8core (new. old one was ryzen 3 2200)
GPU: RTX 3060 geforce 12gb (new)
RAM: 16gb (1x 8gb new, 1x 8gb old)
Power supply: 850

I'm afraid I already know the answer, but I'm hoping to get a new insight here
 
Power supply: 850
850W is the advertised wattage of the unit. Please state the make and model of the unit as well as it's age.

RAM: 16gb (1x 8gb new, 1x 8gb old)
You should give us a breakdown of the ram in your platform.

I believe that one or more pins are bent.
Include an image(or images) of the CPU's pins.
 
Motherboard: Asrock A320M HDV 4.0
RAM: Crucial CT8G4DFRA32A
PWS: Aorus P850W

Ps: hope the images are good enough. Got a tremor so taking pictures can be hard
In the first picture, it appears to me the 6th pin from bottom on the left side is still bent and the 7th pin from the bottom is missing completely. On the 2nd picture there may be one or two pins missing on the lower right corner but it's hard to tell from the fuzzy image.

Examine those locations carefully with a magnifying glass with the CPU sitting stable on something solid.
