Done (thanks for the tip), the PSU is fine.

So it has to be the mainboard, because if it was the CPU I would at least hear all my fans turn on.

Hard to say. but CPU being at fault is not likely. Board malfunction would be greater tongue.gif

One of my previous computers (a Dell Optiplex GX+ if I remember correctly) refused to switch on when we removed some components (CD drive, etc), but I've never seen that on another computer. So even though it's extremely unlikely, it's still possible.

The lights on a dead motherboard can still light up

I had a Rampage III Extreme that was dead but all the lights would still turn on

Then take out the motherboard for a RMA.

Ok, so just got my motherboard back. It was repaired by Asus.

The company where I bought the MB checked it before sending it back to me and said it post OK.

I installed the MB, pressed the powerbutton... nothing. Still broken.

Could it be that my PSU kills my MB?

update,

I unplugged the HDD and DVD power cables, now my motherboard suddenly does power up.
HOWEVER, I still get no bios (or something on the screen) and a continues peep. To my knowledge that means faulty powersuppy. Am I right?

I don't know how it can be the PSU if you tried another one although from my experience problems powering on can only be a faulty PSU or motherboard. Anything else, the system will still power on just wont POST.

Have you tried bump starting it by using a flat head screw driver to bridge the pins? Maybe its a faulty power button on your case?

the powerbutton was my first guess, the mainboard also has a powerbutton.

No sequence, just continuously....
The qled was A0, so no problem there.




BUT
I have solved the problem, I checked the power cables one by one. When a certain cable was connected to the PSU the MB didn't post. This cable is connected to my soundcard and cpu cooler (H100). I reconnected these devices with the same cable and suddenly my PC works again. (very strange)
I guess the cable is broken somewhere and short-circuited my PSU. Will replace the cable tomorrow.

Marshmallows? if only...
