How can i tell if my motherboard is dead

[shawnmetzger21]

i tried breadboarding, even the ones suggested on this site, but i cant seem to point out for sure which of my components are at fault, firstly i turned on the system with just the mobo, psu (known good one) , cpu, hsf and mobo speaker and i got some no memory beeps, then i put in my memory and it just sits there with just the fans on and no beeps. What is my problem, is it the mobo? Btw i couldn't get the mobo started with a screwdriver on the pins, the pins somehow don't work (even with the case power button connector) but i get power by shorting (with a paperclip) green and black wires on the psu 24 pin connector. Sorry for being such a noob.

New or old setup? What components?

Then it looks like a motherboard issue. I sugegst RMA-ing it. Not sure about the CPU too.
