Hello I built a computer today (first one). I connected all the cables I needed and then when I finished I powered it up and the Cooler Master Storm Enforcer red light comes on above the power button and fades away right after. The fans are connected but do not spin. The heat sink doesn't spin. If I put my ear beside the PSU I hear something like Chi-ching. If I try turning it on again it doesn't unless I plug the cable out the wall and in again and flip the switch, sometimes that doesn't work either. I tried the power button my Asrock Z77 Extreme4 but it did nothing. No post beep.

Specs:
Intel i5 3570
Asrock Z77 Extreme4
Corsair Vengeance 8GB (2 x 4GB)
Seagate Barracuda 1TB
TP-Link TL-WN881ND
Cooler Master Storm Enforcer
Corsair CX 600W Modular
Lite-On iHAS124-04

did you use the motherboard standoffs. on the mb edge did you plug in the eight pin power plug?? take the power supply out does it turn on with the green wire buypass trick??

Having to unplug the power supply from the wall to get it to turn on again tells me that one of the protections in the power supply are being tripped. I'd suggest making sure nothing is being shorted out.

I used the standoffs that came with the case. I did use the eight pin power plug but the weird thing is there is 1 square and 7 'triangle like squares' on the power cable but on the board there is 2 squares and 6 'triangle like squares'. What is the green wire bypass trick?

Are you sure you plugged the correct 8-pin cable into the motherboard (EPS12V, not the PCI-E Power)? Both the EPS12V and the PCI-E Power cable look identical, but can cause a huge headache if plugged in wrong. They are keyed differently, but can be forced into the wrong spots.

The green wire bypass trick is a way to power on the power supply without a motherboard attached (which has the power switch connected to it). You connect the green wire on the 24-pin main connector to the black wire next to it (you can actually use any one of the black wires, they are all ground) to "hotwire" the power supply.

However, what worries me is your description of the 8-pin power cable. I'd double-check that connector.

I checked the wire and it is the correct one but it looks just a little different then the slot (the squares). It fits perfectly though. Too bad I don't have a paperclip at the moment, I'll try to pick on up as soon as possible.

I just tried this and air started coming out my PSU and then I plugged my CD Rom and HDD and they started working. I connected the molex aswell (my fans) the fans turned on for about a split second. So what is the problem?

Did you connect all the fans at once, or one at a time? If they are connected directly to the PSU, which it sounds like they are, they should run at full speed as long as the power supply is on. You may have a bad fan.
