New Build Wont Turn on

Recently put everything together, plugged everything up, touched the case numerous times after every few minutes, pushed the power button and no response, no lights, no fans, nothing.

Did I plug something up wrong? Or did I fry something in the process? I only touched my case every few minutes, but I did not have the PSU plugged into the wall.

I just want to know should I troubleshoot everything and start all over? Or is there a better way to tell what the problem is?

I'm hopeful that I plugged everything in, and I double checked and tried to push the plugs down as much as I could without destroying the MOBO.

Whatever help you can offer I appreciate, basically, there is no power going through my setup, and it's frustrating because I don't know why. What's defective and whats not?

First try the "no duh" stuff.

Is the toggle switch on the PSU filpped on?
Is the outlet that the PSU is plugged into connected to a light switch that needs to be flipped on?

Once you have checked that stuff, look at the 24 pin mother board connector. Check to see that all 24 wires are connected to the end of the plug. If a certain one falls out, the PSU won't power anything. Sometimes they fall out.

Also, check the case to motherboard power switch connection. Sometimes you need to turn the connector 180 degrees as it is possible to install it backwards. You could have + and - wrong. Actually redo that whole area with MB manual in hand. I'm talking about the power button, reset button, power LED, HDD LED stuff. You may have mixed them or connected them backwards.

I just tried that, nothing. Matched up the arrows with the positive sides and everything.

Using an 8 pin CPU connector, it only went in one way.

Is it the motherboard?

I'll just troubleshoot the PSU and then the motherboard via a paperclip/screwdriver.

I can do this inside of the case no problem right? Or do I have to pull and unscrew everything to make sure?
