Im thinking I have a DOA mobo. Setup for a bench test with a ECS Nforce6M-A mobo, Phenom x3, hyper 212, ATX 520w, HD6850, & 1G Ram. I'm trying to short the pwr on switch and hopefully I'm just not doing it right cause I ain't gettin' nothing, no fans, no lights (none present), no post beep. I have tested the PS to be good and tried 4 different sticks of ram. What is next to test to prove the mobo bad?
