If you have another motherboard that takes your CPU, or a CPU that fits in the motherboard, you can try that. Not much you can do beyond that.

I remember this guy from another thread. A bad PSU was ruled out, as he says in the OP.

In general...swapping components out...is probably the best way to check for motherboard/PSU/CPU failures, IMO.  This must be done systematically, not all at once.  Of those three, I would expect PSUs to have a higher failure rate.

You see, I'm pretty sure that it wasn't the Cpu because my little cousin plugged in a random cord with 2  pins i believe tjat was from the power supply and i think overpowered the mobo and I don't know how to fix this.

Well if you think the mobo was blown out, you would probably have to replace it.

Can the cpu cause the computer to not turn on? The cpu is more expensive then mobos generally right?

Yes; and generally yes. There are a few motherboards that are more expensive than an i5, but they're not high-volume sales.

If you are using a dedicated card, it should be on a pcie slot on the mobo.
If you are using integrated graphics it is built into the cpu.
