Hi, this is my first time building a computer. I plugged everything in, and it turns on for literally about .5 sec, I can see the LED's of the fans go on then it goes right off. When I click the power button again, nothing happens. Then, I unplug the wire from my PSU in the back, change the volt to 220 then back to 110, and plug the power cord back in, and it does the same thing. And I have to keep switching it from 220 to 110. I live in America\VA btw...so it should be on 110 right? Thanks..
 
Definitely should be set to 110V. Sounds as if you're overloading the PSU. Whats in the system and is the power supply big enough??
 
Leave it on 110. Do not ever run it at 220. Hopefully you did not blow up your system ;)

A common mistake for new builders is not correctly hooking up the front power header. Each motherboard manufacturer is different but sometimes getting the +/- right on the front i/o wires can be tricky. I would pull those all off and try connecting them again, slowly, to make sure you have the correct +/-. Keep in mind usually the second row is reversed of the first row. This is important because usually, even if the motherboard or cpu is dead, the chasis will power on and fans will spin etc. If it's not even doing that, it tells me the power header is not hooked up right.

Also, if it does power on but doesn't start up and just beeps, keep track of the beeps (post codes). They help diagnose problems.
