New build. Display not working

I've built 2 computers before no problem. This time, I can't get the display to show. The fans (including CPU), the GPU, all work. The mouse lights up, but the keyboard does not work, nor does the disk drive. I'm pulling my hair out. The monitor works on a different PC.

Motherboard: gigabyte 970a-ds3p

GPU: MSI GTX 1050ti

CPU: AMD FX 8350

RAM: G SKILL F3-12800CL9D 8GBRL

PSU: 500W

I unplugged everything and tried again.
Tried different RAM slots.
4 prong is connected next to CPU as well as 24prong and graphics card.

Note: this is my younger brothers computer and had a small budget. I know the CPU is... Not amazing.

Yes, you definitely need to pull it back apart and check the CPU. I have no doubt that it may be the problem. CPU should NEVER be difficult to install or to lock down the lever. Heatsink CAN be a PITA sometimes, but shouldn't be "hard" to install. Likely, there are bent pins.
What is the model number and brand of the power supply?

Is there a CPU cooler installed and is the fan connected to the CPU_FAN header on the motherboard or is it plugged into a different fan header?

Have you tried only a single memory module, instead of multiple sticks? Then tried each of them individually?

You may need to pull it back apart and make sure you didn't bend any pins on the processor. This is something we see pretty often around here.

Is the graphics card installed in the PCIEx16 slot and not the PCIEx4 slot?

Check both ends of the monitor cable to make sure there are no bent pins on the connectors?

PSU is raidmax rx 500 xt. The CPU fan is plugged in the the CPU fan header. I have tried single RAM in all the slots. GPU is in pcie x16. Monitor cable is fine. I'm wondering if it's the CPU. It seemed more difficult than normal to get it to fit properly, and the heat sink/fan was a pain to lock on.

This is exactly it. Pin was bent. It apparently doesn't fit well for my mother board. Was able to get it to work though.
