| Post subject: | Problem Powering up Silverstone LC11-M |
Hey Guys I finally took the plunge and ordered my bits for my HTPC, and slapped (well carefully placed) it all in my nice and shiny LC11-M case. Wired up everything and sat back ready to go... Pressed the power button... nothing! Well actually something, the fans try to start spinning (one of the case fans spins a couple of times, and the power supply and CPU fan twitch) but that's it. 
Can anyone suggest anything? Is it a problem with the case, or the MOBO? Any help greatly appreciated!! |

Does your motherboard have somekind of status/power LED mounted on it? Check whether it's lit up or not as per the manual. Check your power connections and ensure that the main ATX/ATX-E power connection is seated properly. In addition, check that the additional 4/8pin power connectors are fitted/correctly seated. Moving stuff around often makes the connections go a bit loose. Is your PSU beefy enough for your MB/Processor/HDD/cards combo? If the drive is PATA, check that the cable is the correct way around, some cables dont have the key fitted. Bruce S. |

The board has a light on it (green) which means that it's getting power. Both the ATX power is in and seated properly, and the 4 pin jobby is in too. I've started removing bits, so disconnecting the DVD drive, and having no PCI cards installed. So it's just the HDD (SATA). |

It's a long shot, but something that got me once... Check the back of the power supply - if it has a switch for selecting 110V/220V, make sure it is in the right position. |

I'm in the UK, so I think it should be 240V but I'll check that when I get home. I've found this: http://www.planetamd64.com/index.php?showtopic=25707 which sounds like other people are having similar problems. Is it possible that there is a short happening somewhere? I think I'll try removing everything from the case tonight and giving that a go. |

It does sound like something is shorted and the power supply is shutting down to protect itself. I had that happen a couple times when using metal standoffs for the motherboard. I found the problem by removing both the power supply and the motherboard from the case and then trying to power it up. Everything worked just fine so I knew I was shorting to the case somewhere. Best of luck to you. Martian |

Well after removing the MOBO, still no success, so I tried to remove the power supply... which I couldn't manage, but when I unscrewed the 3 screws holding it in... it worked!! Turns out that one of the screws holding the PSU in place was causing a short circuit on the LC11-M case. Removing that screw and having the others in place, and hey presto... a working machine! Next step, putting all the bits I've ripped out back in again! Cheers for your help guys! |

Were you using the short screws usually supplied with a PSU, if so, I would get the the thing replaced, as there is something seriously wrong with the insulation/isolation clearances. Bruce S. |

Well the PSU came fitted, so the short circuit was happening with the screws it came with. 
I'll have a look tonight and see whether the screws look too long or not. I really don't want to have to go through the whole faff of returning it and then not being in for the new delivery and going to the depot blah blah blah... |

If you had caused the short I would say just go with it but with it coming shorted out from the factory I'd try to get a replacement. Even though it has protection circuitry being shorted out still put some strain on the electrical components that wasn't your fault. I know it's a hassle but I'd hate to see your supply die a pre-mature death, especially right before an important show! Good news is you found the problem, I know how frustrating it is to push the power button and have nothing happen. Best of luck to you, Martian |
