My second PC was the first I built personally. After assembling it, I turn it on, a green LED on the mobo lights up, all the fans and the HDDs start turning for a second or two, then everything turns off. I try both reset and power button, nothing happens, I turn off and on again the PSU, again everything turns on a few seconds, then off again, after a few tries, I give up andtake the PC to a store's technicians. A few tens euros and they give it back to me perfectly working: I hadn't connected the case front panel to the mobo.
