Id be willing to bet your motherboard is grounding itself out. Make sure you're using standoffs on the motherboard and make sure nothing behind the motherboard is touching the case. Make sure whatever you're using to screw the motherboard to the case isnt conductive and make sure you're using non conductive washers around the mounting screws. usually when a newly built PC doesnt POST, its because its grounding out. If you can hear the fans spin up, the board is getting power. bad cpu, bad video board, bad ram, bad hard drive .. none of these will keep your PC from posting. *edit* oh well just saw you sent it back for a return. Just keep this all in mind when you mount your new mobo |

any type of grounding will most likely make the psu smoke or atleast make that electrical burning smell.. |

The MB light came on. I talked to the people at Newegg and they confirmed it was DOA. I'm shipping it back for a replacement tomorrow. |

I'm with this guy. And no, grounding out a motherboard does not cause PSU's or other parts to fail or smoke....it just stops the motherboard from even hitting POST. In my past experience with having a mobo seated improperly the fan would whirr for just a second and then power would turn back off. Right at that part where you would hear the POST beep is where power shuts down. |

That shows where you put the standoffs, making it easy for you to make shure that you put standoffs where the holes are in the mainboard. Using any metal or conductive screws is not a problem as long as you use them in the holes designated to seat you mainboard. Also I would like to think that if you have shortcuircuited your mainboard the PSU would have switched off especially if you managed to fasten it in the case without using standoffs. All fans should have stopped running aswell. Forgot to make that last into a question aswell. The first time you started the computer did something similar happen. Did your PSU switch off instantly? I'm so broke. I can't even pay attention. |

I had an extra PC that was missing some standoffs in the case so the mobo would ground itself all the time. Caused no damage, just wouldn't post and would shut off if it grounded during operation, I finally just stuck a piece of paper underneath the mobo to insulate it and had no probs after that. I've also seen mobos not even beep/post if the ram was bad/seated improperly. |

So it won't post if there is no RAM in it? |

Hey there Brif, Did you use standoffs as the poster a couple posts above asked as t hey are needed so Mobo does not ground itself out. Also as another poster mentioned using a vga and dvi plug on one monitor is unheard of usually its one or the other, or did you mean you were hooking the vga into a dvi adapter then into the vid card?
Also make sure you have the power sw,reset sw all seated on the right jumpers in the right way(negative/postive) And im sure you have done this but did you apply t hermal grease correctly if you used that as to heavy or to thin can cause computer to post for a second then kick itself off. also did you say you have a floppy drive as well? try leaving it off the mobo as sometimes a bad pin on those can stop you from posting when it goes to detect the hardware. I'm sure you have done all the above but just checking and computer should post to the point when it detects the ram then let you know it has no memorty or not enough the messages vary. |

Sytand offs go in the little holes of the case to support the motherboard :

Check your Video Card. If you have an onboard video card and are using a seperate pci express card make sure you disable your onboard card in your bios.Make sure you have connected your HD cables correctly and that they are in the correct slots.As stated above verify that your HD is working. I am pretty sure your Ram is not the issue,I have rarely ran into Ram issues in past Computers I have built.Check your Monitor and make sure it is operating as well. Another thing that can cause you to see nothing is if your Video Card cooling Fan is not operating check to make sure it is on and cooling.In your Bios make sure you are booting up from the correct slot. In your bios you can name what you want to boot up 1st. Most people have their PC's boot up from CD Rom nowadays,but a few still boot from floppy if you have an older system. Hope this helped:P |

It's possible to have the fans spinning and the motherboard never actually reach POST. What happens is the motherboard is constantly resetting until it receives a Power Good signal from the PSU (signifying the PSU has stabilized after a cold boot). During this time the fans are spinning, but since it never gets the go ahead from the PSU it doesn't do anything. This is usually because of a bad PSU.

Hmmm, if you get no power, did you reverse your Chassis' wiring on the panel connections on the motherboard? No power usually at the beginning makes me wonder if you have your grounds plugged into the positive. Reverse them and see if any power comes on (and try this barebones, no hd, no components yet). Edit: Black or Red, or one set of color is usually the grnd wire. If you have multiple colors those could be the positive. |

Make sure the pc is plugged in and you hit the on/off button, I heard it works wonders. |

Originally posted by wayubb I used standoffs. I didn't have the vga cable all the way in my monitor so I thought I needed both. All the jumpers were correctly seated. I just opened the box and set the mobo on a long non conductive piece of plastic and only put in the ram, processor, CPU cooler, and video card. When turned on, the ram light does not come on, I tried several ram combinations but none of them work. No beeps are heard through the speaker when turned on. The mobo is DOA, i'm positive. |

Would like to see a picture of the basic system build outsie the case.
no beebs means no mem. probaly got nice looking uselsss incompateble memory ? do the fans turn on (cpu) video card.
I just make the comment but i guess you have done so.. the p4 and video power plug on the right place ?

I had the same problem with my new PC. It was a loose chip on the motherboard. The chip looked fine untill i pushed down on it and felt it snap into place |

Brif,
Check this out. One thing you want to definately take a look at is make sure that there are 2 POWER connectors for you motherboard. Back then when i built my first motherboard i was having the very same issues you were. I messed around with just about everything and that's when i noticed that the smaller connector on the Motherboard wasn't actually sitting all the way in from my power source. I then took it out and placed it back in and sure enough the everything powered on instantly One thing to also note. If you have the bigger connector of the two seated then you should see the Motherboard light turn on once you apply power to your system. if that does not come on then your guess is probably correct your MB is DOA. if it does come on then your motherboard is just fine. Try the above and let me know what happens. Also, if you could provide me with the motherboard model I could probably explain this so much better. Sorry i'm still new at the terminology but I know my computers like the back of my hand. |

It sounds like you may have wired the case to the motherboard wrong with the Power switch , HDD LED light etc those wires if you got a motherboard that doesn't offer the bracket fitting to make it easier. Refit those wires but turn them the other way on to the pins. The other scenario is you've EMP damaged your motherboard during the build. Double, triple check all connections. Disconnect all case fans for the troubleshoot. Once you hear it can power up plug the case fans back in. Is your PSU suitable for your new build? Using your older PSU or brand new one? |
