I tried both but no luck

What do you mean by reseating?

No I haven't tried outside, does it need to be connected to anything or just the wall outlet?

Is the power switch connector one of the small two colored cables?

It's an EVGA 700W bronze, and yes I turned on the switch. Also to note, some blue light shows up on the front of the case but it still doesn't turn on the computer.

I'm pretty sure I have got all the cords on my power supply plugged in correctly, I have looked up multiple tutorials and even got a friend to look at it but it still won't turn on.
