Failed power supply??

Just moved home and my PC now wont come on...

I've checked all the cables and everything. I'm guessing it's the PSU because i've had others die before and got the same kind of thing. The lights come on on the motherboard to show its getting power, but the system don't power up at all. Pressing either power button on the case or motherboard doesn't do anything. Tried clearing CMOS but don't help.

It cant be things like RAM, CPU, graphics cards, or SSD's because the system would atleast come on and display an error/beep. So it has to be either the motherboard or PSU right?

Is there any way to check the PSU? I've got a multimeter but not sure what cables/pins i need to check to see if power is going through them...

You could have a short somewhere... you can hotwire a PSU to fire it up for testing. There's instructions here: http://4volt.com/Blog/archive/2009/03/12/howto-hotwire-a-pc-power-supply.aspx

Thanks. I managed to find another PSU though and the PC still wont come on... so it would have to be the board? Because even if a CPU or RAM is faulty the board will still power on right?

have you tried removing the memory and seeing if the mobo realises it has no memory in ?

if you can, take the motherboard out of the case - remove all RAM, SATA drives, graphics cards and other PCI-E devices you might have. Then hookup a monitor to the onboard graphics, a keyboard and the PSU and try starting it up outside of the case.

More often than I can count, when nothing at all happens when you hit the on button, you're shorting something on the case.

Thanks guys, just tried all that and still nothing. I was asking around on the Asus forums and apparently this is pretty common issues with this board (Rampage IV Extreme). Which is ridiculous considering how expensive it is.

I bought the board roughly 18 months ago, so does anyone know how i RMA it? With Asus direct, or with the place of purchase?
