It seems like something is wrong with your PSU or the 24-pins connector.

I will try to unplug and replug everything....

Shut down the PC and unplug it from the wall socket for 5 mins. Take out the CMOS battery for 5mins then put it back. See what happens. And also check the BIOS version, if its the latest one or not ?

I have to check if is the last or not, just got the mobo today... Psu always worked, i doubt it is malfunctioning... Maybe with a clearcmos or an update it will work just fine. Meanwhile, if anyone have different feeling about what could it be, it'll be more than welcome ! When I'll be home I'll try with your suggestion

Ok, bios updated, all cables unplugged and plugged again… no improvement…. Won't shut down. I've even tried to remove all the pins that connect the mobo to the case and switch it on from the motherboard but nothing, still doesn't work… ideas?

Did you clear the CMOS by removing CMOS battery ?

Of course I did. Actually I did try the paperclip test as well just to see if the PSU would shut down by removing the bridge on the two pins, and it did. So motherboard is on testing now by my retailer. We'll see on monday
