I have just got a new frount for my case off of the company I brought it from as when they delivered my original it was broken. But im having problems turning the thing on. I dont know if its the cable from the on button on my aerocool 3t extreme case or my asus p5k mobo or my therematake psu? I have all the connectors plugged in where it says to plug them in but nothing. What should I do?
