Is it motherboard fault or...?

[SuCkDuBsTeP]

Hello guys, yesterday I bought new motherboard for my second pc from p5ql-mx 1333 to p5ql pro and with motherboard I bought core 2 quad q9300 and ddr2 2gb ram 800mhz and I connected everything and when i press power button nothing happens.

So first thing i thought I didn't plug in correct panel my power sw cable.So I mixed everything I put in almost every panel I could and then I finally got it and my pc turned on. And then as I thought It says HDD not found system halt because my HDD was long time in old motherboard with new bios. Then I unplug everything and now I cant remember where did I put my power sw on which panel. I literally tried everything like my case power sw doesn't work on this motherboard. I thought its my psu but its brand new from my main pc. So I change motherboard and power sw works as a PSU. Motherboard works fine all LED things are on it. What do you guys think it could be. Tomorrow I will take it to service so they can fix it ...

Edited much of your original post to include, proper grammar and punctuation to the best of my abilities and of what time would allow me. Please maintain that the main mode of communication on the forums is in English and without conveying the right message, you may not get the right answer. You probably would/could get some posts albeit after a very long time.
