Motherboard Problems

[Izerpizer]

So I was recently fixing my computer that had died and I bought brand new CPU, RAM and a Motherboard. I got everything together and I was just going to boot it up by manually connecting the front panel power pins, I saw a big spark and now the computer does not boot up at all. No signs of life whatsoever. I may have connected the wrong pins. Can this kill a Motherboard?

Unplug the IO other than the power switch.

I don't see plugging say the positive LED to the Negative LED input would do anything like that.

What PSU do you have?

Did you replace it?

How did your old PC die?
