I have some issue on a computer, and after several tests I found out that the only way to safely turn on the computer (otherwise it is dead) is to keep the paperclip on the atx connector and push the button on the front panel. This is the only way to fully boot the computer. After the computer is booted, I can take out the paperclip. The motherboard has already been replaced once. It is a PSU issue? What is going wrong?

  • Just replace the ATX power cable, sounds like the cable is defective, the paperclip is completing the circuit but having such a low quality metal doing so is just asking for trouble. – Ramhound May 23 '13 at 15:54

    do you have a spare power supply? or another computer to borrow it from? If so, test it with a different PSU – Keltari May 23 '13 at 15:55

    Terix - Did you figure out exactly what your issue was? I'm having the exact same situation, & using a spare power supply cord from another computer makes no difference, so I'm wandering if your situation was what Ramhound said, or something else. – user394950 Dec 1 '14 at 14:41
  • I've made an offical answer for this, and it's not good news. Hope it helps. – Terix Dec 10 '14 at 23:07

This issue is a symphtom of a failing PSU. After a couple of weeks of this mess, the PSU failed completely and died.
