Motherboard dead? Light comes on but thats it
Power LED on mobo comes on but nothing when you hit the power button.
Can I assume the mobo is dead? Also, just to rule out a power button problem, is it acceptable to short (with a jumper) the two-pin power button header on the mobo to force a power on that way? |

Yes to the second question. |

Same result with a new PSU as well... How would you test a PSU? |

That way you can test the PSU with it switched on (under load) to see if it`s delivering the correct voltages. As for the other supply you tried, was it adequate for the job ?. |

Initial PSU was a 250W Bestec, the new one is a 350W one... Assuming the new one PSU is OK, would you assume the mobo is indeed dead? |

You need to Know you`re getting your correct voltages under load. |

No. Reseat all cards and memory. Try disconnecting or removing all unnecessary items. Google motherboard capacitors and look for pics of blown caps to see if that is your problem. |

OK. First PSU wont even power on with Pin 14 shorted - so thats knackered for starters. |

There is a green wire you can short to any black wire to power on the PS. Best to do this in place so the PS has a load, just use a paper clip to short green and any black. http://www.bluemax.net/techtips/ATXP...pplyWiring.htm -- Phoebe http://wanderingspace.net/wp-content...e_portrait.jpg or http://tinyurl.com/2m77bp |
