Is nothing coming on whatsoever? I would say your best bet would be to unplug your 24pin plug and the one near your CPU and try plug them in again properly, see if that helps? Maybe something rattled loose in the mail? If that doesn't help, then we have to eliminate the possible culprits: psu, mobo and CPU.

Aaah, man I'm so sorry... I can imagine how frustrated you must be, nothing can make one more angry than a new pc that just won't frikken work! Especially if it was pre built, the last thing you want to do is take it apart...any chance on rma'ing it? But the problem you describe it sounds like the psu, because nothing is happening... Just a question, I'm not doubting your intelligence or anything, is the psu switched on and set to the right voltage?? We must never overlook these small things!

Don't worry about insulting me, I just want my computer to work. I know the psu is switched on but how can i make sure it is on the correct voltage? Thanks for responding

no worries! well its normally a little red sliding switch on the back of the psu, next to the on/off switch. some new psu's dont have them though, they can automatically select the correct voltage. the next step would be to try a different psu, at to rule it out. but if you bought it pre built. i wouldnt fiddle too much, rather get hold of the people who sold it to you.

if you do not have a spare psu, you could try the paperclip test, that will give you some idea if the psu is working at all. its not foolproof however and even if the fans spin up, the psu may still be faulty.

Check all of your connections, especially the 24 pin on the mobo. If everything is tight, it's gotta be the power supply; a bad mobo will give some sign of life, even if it shuts off again right after you press the power button (lights, fan, etc).
