Raja - I have a question for you:

I bought a little P8Z77-M Pro for a netbox upgrade for the missus, along with a 3770K and 8GB or Ares rams. When I assembled it to start working with it I could not get it to POST. I tried two different sets of ram and three power supplies, all of which came out of running pc's and still no go. So I took it back to the place of purchase where the store guy appeared to run into the same symptom, after swapping rams, cpu and them mobo he still couldnt get it to boot, so he tried a new power supply and it booted. After finding that he had to backtrack and retest everything, eventually he had the original combination of parts back together and it booted fine. To his credit he exchanged my mobo anyway but he told me that it was not the cause of my problem. When I got it home I tried my psu again and still no POST. So today I bought a new HX650 for another build and it still will not POST, so what could I be doing wrong? The mobo is resting on the mobo box, its not in a case, factory cpu cooler for testing, and the same Ares rams .... I really do not understand what is going on. The power LED on the mobo lights up and that is all the mobo does, no fans spinning, no POST LED's , nothing.

Any help would be great.
