I bought a new CPU fan and when i took the one I had it came out with my CPU(AMD Ryzen 7 I stolefrom my friends abusive ex so I can't even be upset if it breaks and I was careful I made sure I was grounded when handling it)inoticed the pins in the corner were bent. I unbent them but I noticed these were gone. This is the corner opposite the corner with the arrow. I had to install this when i bought a new motherboard and it was fine ever since so I know it was fine before. So to get a background on what circumstances left to my question.

My monitor gets no signal when I turn it on. All the fans work including GPU. None of my USB ports work so I can't use the mouse or keyboard. I used different monitors, and even tried my display port. There are zero beeps, Motherboard AMD B450,and I even reseated my RAM and GPU. I also took out and put back in the CMOS battery, and flashed the bios. I've tried Google to no avail. I also don't have a second motherboard to test with. I'm going to get it diagnosed at a repair shop but I'd like to know is I have anymore options. I'd just move the components to my Walmart Intel motherboard but it doesn't have M2 for my SSD.

This is my first build. I have a background in tech but never got into the career. Is there anything I can do to salvage this or will I have to actually buy my own damn CPU?
