So i am building my first computer and I have everything connected correctly, but when I turn it on this happens in order:

Power supply (Corsair HX650) powers on
CPU fan turns on
Power supply turns off
CPU fan turns off

Nothing else happens but it just keeps going in a loop, and the hard drive and cdrom doesnt turn on.

One time it powered on and did the order but the power supply stayed off and everything else turned on, there was no screen signal.

Try pulling the DRAM and try with a single stick, firmly seated, if all goes well try adding the other stick (guessing two sticks)...if no joy, what mobo, CPU and model # of your DRAM

When I took it out and tried powering it, the power supply fan didnt turn on but the cpu fan is just turning on and off.

I have the ASRock Z77 Extreme 3, Corsair Vengence 8gb (2 x 4gb), Corsair HX650, GeForce GTX 760 4gb RAM, intel core i7 3770k

May be a bad PSU, can you borrow one to check?
