PC I Built Will Not Start Up
Hello all you wonderful folk. I would like some advice and help with my
computer that I just built. I transfered the parts from my old case to a new one that a friend bought me. I did not add any parts or change anything...hardware wise. It is just a new case and power supply. I took my time and made sure all the rizer and MoBo holes lined up, did not remove the CPU or RAM from the MoBo...just the PCI cards and Video. All the parts are in the new case and when I plug it up and flip on the rocker switch on the power supply the machine lights up and fans spin for 1 second and then turns off. The MoBo LED lights as long as the power supply is on. The power nor reset buttons do not turn on the system. What am I missing or doing wrong? I also want you to know that doing this has taken me 12 hours. I am visually impaired and because of my eyes have to work slow. To the best of my knowledge all the connections are correct, but I must have missed something...it will not power up. Here are links to the case that I have as well as the MoBo PDF file. Thank you all for the help. I am excited about my new case. I have never had a case with a window in it, led fans, and digital display. ftp://download.intel.com/support/motherboards/desk... http://www.newegg.com/Product/Product.asp?Item=N82... http://www.bccpc.com/712-4hlw-bk.htm Thank you al again for the help. I need to get to bed. LOL I know that 12 hours building a PC is very long, but hey I am enjoying doing it myself even though it is hard for me to see it. |

I built a system recently that had similar symptoms. It turned out
that the connecter from the power switch had to be turned around. For whatever reason, one side of the switch was actually gounded, and that side was being connected to the active power-on signal and keeping the system turned off. Once I reversed the plug, all was good again. Chris -- Chris Richmond | I don't speak for Intel & vise versa |

In doing a swap like this, especially involving the PSU, make sure that the 4-pin supplementary 12V is connected to its header on the motherboard, in addition to the regular 20-pin power connection. It might have been overlooked as newer PSU's now feature a 24-pin power connector or the square 4-pin block no longer exists or needs an adapter. If there is a [PSU] manual, check it. |

Simpleman,
It looks like all the other guys have summed it up pretty well, but I have another two suggestions to add to the mix. First try unplugging and then replugging all of your data and power connectors one by one. If that doesn't get it going, try removing and reseating your video card and any PCI cards. Make sure all your connections and cards are plugged in all the way. This may seem mundane and unnecessary, but from experience I've actually gotten computers to work by doing this. Sometimes the cards won't be seated all the way and this will prevent the computer from booting. AGP Video Cards seem especially prone to this when they don't have the little plastic holders on the board. Another reason this works is occasionally the metal contacts in connectors will get a little build up on them and cause things not to work unless they are seated "just right". Oh, and another thing, if you try Lance's suggestion (which I'd highly recommend), and the computer powers up with your old power supply, you may still be able to get your new one to work before you go through the trouble of sending it back and having to do all your work all over again. Disconnect your power supply from all the parts inside the computer. Take a metal paperclip or small piece of wire and your going to short circuit part of the main motherboard power connector. Connect the green wire with any one of the black wires, then plug your power supply into the wall for about 3-5 seconds. This should cause the fan(s) inside the power supply to start spinning and you'll be able to feel air being lightly blown out the back side of the power supply. Unplug the power supply from the wall, reconnect all of the internal connectors to your components, then plug back into the wall to check if it works with your new power supply. Depending on exactly how bad your vision is, I'd suggest finding someone to try this for you. It's not difficult, but I've never been around to find out what happens if you short out the wrong two wires; it can't be good (unless you're a pyromaniac or like to be electricuted). This is an old-school computer tech trick that I picked up years ago, and it has a surprisingly high success rate (~25%). Daniel |

PC I Built Will Not Start Up
OK folks, here goes. (This has been a long computer build...LOL). I now
have the PC up and running. Here is what I did. I took it all back apart...everything out of the brand new case...even the 500 watt power supply. I then placed the MoBo in the case gently with no risers and took toothpicks and placed them through every screw hole in the MoBo. Then where the toothpicks came through the screw holes on the case I placed a green mark with a Sharpee. I took the MoBo back out and placed risers where my green marks were on the case. I put everything back together and built the PC and put the 500 Watt power supply back in the case. Pluged it up and sure enough...the same issue....it would run for 1 second and shut off. I knew that the MoBo was mounted correctly so it could not bed a short. Come to find out...this is a case with a polorized reset and power turn on lead. They only work one way...if they are backwards that act like a turnoff switch. I knew the rest and power on wires where in the correct place on the MoBo, so all I did was flip them over and sure enough the PC fired up, booted, and is working like it should. Now I need to finish all the front panel connections....case speaker, and all those little do-dads on the front of the case...temp monitor, front panel USB, and audio. Once that is done it should be complete. I may be back with more help with those...they are labeled but notg sure what the labels mean. Thanks for all your help. |
