Question New CPU, PC doesn't turn on anymore

[sleepyz]

I bought a new CPU (Ryzen 5700G), it arrived earlier than expected so I turned everything off and replaced my old one. The new one has a few bent pins already, so I fixed those the best I could and put it in. I pressed the power button and the light and fans and stuff came on for like half a second and then immediately turned off and now nothing turns on anymore.

I tried putting the old one back in but it still doesn't turn on, now it doesn't even do anything. I looked this up and looked at a whole bunch of different sites and forums, etc and nothing helped. I'm asking here as a last resort because I feel like this is a specific issue that nothing else I look for can help me with.

I've tried basically everything and I want to make sure that I can't do it myself before I take it to a repair shop or just buy a new motherboard or something.

Specs:
GPU: GeForce GTX 1660 Super
CPU: Ryzen 5 5600G (old), Ryzen 7 5700G (new)
RAM: 2 sticks of Corsair Vengeance LPX 16 GB
SSD: I can't figure it out, it's the one it came with. 256GB

I can't figure out the power supply either.

Do you have pictures of what the CPU looked like before you fixed it? Also, would be a good idea to pass on pictures for the new CPU's pins after you've fixed it.

You forgot to mention the make and model of your motherboard. For the sake of relevance, what BIOS version are you on for your motherboard?

On second thoughts, please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

All I know about the motherboard is that it's an HP 8906 on the latest BIOS update.

I don't have any pictures of the pins before or after I fixed it, but as far as I can tell that isn't the problem.

Check to see if that HP model was ever sold with the 5700G.

I checked, but I already knew it was compatible.

New or new to you?!
Why in the world would you take a CPU with bent pins and not return it?

I pressed the power button and the light and fans and stuff came on for like half a second and then immediately turned off and now nothing turns on anymore.

Yeah you can show pics if you like to, so that people can see if the bent pins were power pins or were very close to them because if power pins hit somewhere where no power was expected then you get a nice burned mobo and probably CPU as well.
