  1. seems like a power supply issue check the cables most issues come form them!one may be even unplugged!or then you should make sure the PSU works properly!
  2. check that the 4/8 pin pci power cable is connected. also make sure you used the mb brass standoffs so that the mb not shorted to the case. check the mb case cables..make sure the power and reset switch are on right. with video cards some of them need two power plugs..make sure if your video card has two power plugs both are plugged in. to help you more can you post your spec??

    I think its my PSU. It's plugged in at the wall socket and at the PSU but it wont start when i turn it on.
  4. unplug the power supply and on the 24 pin atx conector with a paper clip jumper the green wire to a back wire. if the ps is working the ps fan should come on and stay on.

    sorry i dont get what you mean with the paper clip
  6. He means:
    a) Open a paper clip.
    b) Put one end to a green wire.
    c) Put the other end to one of the black wires. You see there are 2 lines of pins. Put on the same line that the green wire if you see on both lines black wires.
    d) Power on PSU. If turns on, may happen 3 things:
    d.1) You put something wrong.
    d.2) The CMOS jumper is on clear.
    d.3) Motherboard failure.
    Continuation of d) If it doesn't, then the PSU may be failing. Try changing it see if that works.
