PC won't turn on at all

[Gauss803]

I have recently built a new computer, and when i have everything hooked up and turn the power on the computer will not turn on at all. None of the fans start up and no lights turn on, nothing changes. I have double and triple checked to make sure all of the wires are plugged in to the right spots, and i have even tried running it with just the psu and motherboard.

I tried plugging the psu into my older pc that i know works, and it started up with no problem.
The motherboard, cpu, ram, and case are all new, the graphics card, hdd, and psu are about a year old.

My system specs are:
msi z87-g45 motherboard
Intel Core i5-4570 cpu
geforce gtx 680 graphics card
OCZ ModXStream Pro 600W psu

Is the 24 pin AND 4 (or 4+4 or 8) pin CPU power connected (and fully seated) to your motherboard? Did you get a motherboard speaker with your motherboard or case accessories? If so, have you connected it to see if there is a beep code/pattern?

check that you used the mb standoffs and the io shield or back plate for cpu cooler if metal is not shorting the mb out. unplug case fans and usb ports sometime one of them can be bad or hooked up wrng and cause a no post.

the 24 pin and 8 pin are both properly connected, and as far as i know the motherboard does not have a speaker

Refer to your motherboard manual. In it there should be a layout diagram and a 2-pin header for a small motherboard speaker to attach to. As I said earlier, if either your case or mobo accessories contained a small 2-wire speaker, it's where it would attach to get POST beep codes/patterns.

i unplugged the usb ports and fans but still no response, i also do not have an io shield installed, would this cause a problem?
