Computer starts, then it shuts down.

Hello,
i just started a build and i'm pretty new with this, but what is happening is that my computer will start up, the psu and motherboard start and then the psu just stops a few seconds later. the mobo stays lit for a few secons after that. the only things i have hooked up to the psu is the cpu and the mobo. i just tried a new psu and i'm having the same problem. does anyone have any advice?...

    What all exactly is connected when you attempt to turn on the PC? I presume RAM is installed, and on-board video is connected to the monitor?

    Need a little more info..
    Mother board make/model
    CPU make/model
  2. I hope you have a heatsink with fan installed too. Heat or no cpu fan would also shutdown your system rather abruptly.
