Is my motherboard dead?

A couple of days ago my desktop failed to turn on.

To check if it was a PSU issue I bought one of those PSU testers.

Before testing, I have detached all the connectors, so that the PSU would not power anything.

Attaching all motherboard power connectors to the tester all is good: tester lights up and show correct voltages. If i remove the smaller of the two, the tester is still on even though I read an "LL" warning.

Now, if I connect the smaller connector (12V?) to the motherboard and keep the bigger one (24 pins) attached to the tester, the tester does not light up any more.

Is this a sign that something is wrong with the motherboard? Maybe dead?

Thanks,
Stefano

what kind of motherboard are you using?
also what kind of PSU do you have? i hope the PSU is a high quality brand like Seasonic/Enermax/Corsair/etc.

check the capacitors on the board to see if they are ok (examples of failing capacitors are found on Badcaps.net)

you are not answering my original questions, stefano.
I mean don't be stupid and act like a fool by posting like you did.
If you do not know what brand & model of the motherboard you have in your computer, run either the CPU-Z tool and click on the Mainboard tab of that program or the Speccy program and mention the motherboard here in this thread.
For the PSU (power supply unit), open up the computer case with a phillips screwdriver and look at the rectangular box on one of the top corners of the PC case.

Look like a stupid? What if I did not have time to have answer to your question until now (I did not expect people to answer straight away, in fact you answered after 2 days)

How do you think I checked my PSU with a tester without opening the case? Don't you think I could read the name of the PSU and the motherboard there? Or just check the order details of when I originally bought them?

Do you think I can run a diagnostic software on my machine if it does not power up?
Now who looks stupid?

The PSU is a Cooler Master and the motherboard is an Asus P8P67 R3 both from 2011.
