replaced the power supply, but still nothing.

So as the subject says, i had my computer go out on me. It will not start up at all, not even turn on. No fans, no sounds coming from the computer. It's like the outlet was dead and I was getting no power.

However it was a live outlet, which is not the case. I ordered a power supply with tools, replaced it, put the computer all back together, and still nothing. Tried it in different outlets, still nothing.

What do you think could possibly be the cause? Would it be a bad logic board if the computer doesnt even turn on?

I saw no diagnostic LED lights turn on whatsoever.

Do you have a DVM? So you can measure the AC voltage at the power supply be very careful here!. Then check the DC side is voltage present there. If not then the power supply you got is bad.
