	Welcome to the forums First thing is to check all your cables, make sure you didn't leave any disconnected or connected improperly. The most obvious culprit is typically the 8pin CPU power connector at the top of the board. It can be hard to see with the cooler in the way and is easily missed. That or you could have connected an 8pin PCIe cable to it instead of the CPU power cable which won't work. Odds are you missed something, work backwards and double check everything, refer to the manual if you have to. Good luck and let us know how it goes.

	Thanks for the reply , but i didn't mess with the power supply(at least with the cpu connector totally)(btw it worked before) Still tried reseating the power cable, but the same deal.

	Then it's back to the drawing board Disconnect all the cables from the board and hook up only the CPU 8pin and 24 pin power and your front IO cables (power, reset etc). Clear CMOS then try powering up again. If it works, one by one reconnect the rest, testing in between.

	So, i tried only motherboard power+cpu power + all 3 chassis fans + powerled and power and reset button. Still the same! I'm not sure about anything right now.

	Did you disconnect all the SATA cables etc? I meant everyting, not just power cables. Anything you could have touched when doing your cable management.

	Yes, of course i did. The only ones are power for motherboard and cpu, power for fans and power and reset button and their LEDs

	Hmm, ok so now it gets down to basics. Pull the board from the case and try and run it on top of it's packaging, same as before, only power and power button connected. Do you remember anything out of the ordinary while you were cable managing, dropping a screw, bumping something etc? Let us know how the bench test goes.

	Update: BTW: I didn't read your reply until now. So i just remembered i didn't stick the ram back in! I stick it in and now the system doesn't even start to spin fans! I'm out of luck i think. Will try my best to do what you described in your latest reply.
