pc turns on then right back off

I just built a brand new computer, I have the specs on my signature. everything was going fine until I tried to start it, everything turns on for like half a second lights fans on everything all of it and cuts right back off. No post beep no debug numbers or anything I have tried, taking one Ram stick out and switching them unplugging everything and plugging it back in taking the video card out completely and trying it did the same thing I even tried loosening up on the Mobo screws and still does the same thing. I'm at a lose for words here can someone please help me, everything is brand new I just got it today and yesterday I don't know what else to try. Someone please please help me!!!

  1. It might be dumb but a friend of mine once had the same symptoms when he didn´t mount the cpu correctly i.e. not lifting the lever that clamps the cpu into place. You can actualy place an AMD cpu into the socket without lifting the lever-> obviously not correctly but that can happen to someone inexperienced :)
  2. I remember lifting the clamp and everything, this is not the first time I've built a computer or atleast changes things around. Which I why I'm so stumped as to what to do.
  3. I think your mainboard has an oboard power ON switch try disconnecting the cases power switch and use the one on the board see what hapenes might be a bad switch on the case?
  4. I tried that and didn't work I've tried unplugging everything case related and didn't do anything. I'm really getting frustrated and upset at this point, I really don't know what's left to do...

    you said unplugging your gpu didn´t help? -might be your psu...
  6. Yep I tried the Gpu and the Ram switching and nothing made any but of a difference, I would try the paper clip thing but with this being fully modular I have no idea how to.

  8. Any guess on how to test it?

    not unless you have an old pc lying around or one of these volt/power measure things

    ps: you said you knew how to build a pc, the 12v EPS connector was connected right?
    (sorry kind of standard "are all the cables pluged in" tech support crap lol)
  10. I might have one I could throw on the Mobo just to see, but yeah everything is plugged in I make sure every time I try it I really hope it's as simple as the psu but I don't want to send it in because who knows how long it'll be before I get one back :/
