This is an ongoing fucking saga for me. I would bring up my old topic, but since my Team Member Status went away, I can't I am building a new computer. It won't fucking start up. No diagnostic beeps. Fans work. I have tried two MOBOs (Intel P4) and two ANTEC 450 Power Supplies. I live in bum fuck nowhere so I can't just go down to the store to try something out. Its a 4 week turn around to swap anything out (at least) Frustrating to say the least. If I disconnect the hard drives from the mobo (but stay connected to the power supply, they start to spin. If they stay connected to the mobo, they do nothing. Any advice. Other than a new MOBO and new Power Supply |
Done it. And have replaced both the MOBO and the Power Supply |

So it will start up with the motherboard, memory and video installed, but chokes when you install the hard drive? How about a CD-Rom ... boot from CD. |
I think he means he's done all that and it still won't boot. |
No beeps means bad news. Where did you get this mobo? A lot of cheap places sell refurbs or dead ones without informing you of the fact. |
A bad cpu would still let the mobo boot. How about removing the reset jumper and removing the battery for a few minutes and then putting them back. I had to do that once when I was building a PC. |
zipzoomfly(used to be googlebuy or something), brand new, both times. |
Insult away, I am obviously an idiot. I have upgraded everything in my old one, but this is my first from scratch build. The LEDs work and I push the buttons and the power kicks into the the PSU. But then, nothing. Like I said, the fans work on the Video Card, the PSU Case Fan and the CPU. If I disconnect the hard drives and optical drives from the MOBO, they spin. But if connected to the MOBO they don't. |
Done, No dice. |

The rundown Two DVD drives (one a DVD RW) Two Hard Drives, one directly into the MOBO, the other through an PCI card (both WD 160 and 200Gigs) Intel P4 3.0 with INtel MOBO. Old soundblaster sound card When I start up with everything plugged in both HD and Power LEDs stay lit. Internal LED lights up. Vreg is plugged in. Jumpers are set right. Disconnected damn near everything except PSU and MOBO |
|
What is the Wattage on your power supply, at least a 400? Oops sorry didnt read. Most high end mobos are pretty sensitive. I bet thats what it is. No beeps definitely mobo. with 5 grand you could get a Dell XPS with 21" flat panel with 3 year 24 hour onsite service and still have money left over. |

I've seen this happen a couple of times before. Any chance you have an old PCI video card? Work backwards, disconnect all devices from the MB. Set all jumpers to factory default. Install one stick of RAM, and only connect the speaker and ATX power switch connectors. Use the PCI video card (make sure that the power is disconnected from the PS). The gist of this is that there is still power to the MB when the power cord is connected to the PS, even if it is turned off. Seen a couple of AGP chipsets fried by this. Using a PCI video card will isolate the video issue. Good luck and hope this helps. |
500 not 5000. My video card (and sound card) are the only legacies from my old system. could the video card be causing the problem? The MB has power from the PSU (video card fan and internal LED works) It just won't kick the CPU into working. Anything (except fans) plugged into the MOBO are dead. Unplug the drives from the MOBO and they turn, but that is it. Somehow the MOBO is freezing up. |

check cpu fan conection. Make sure the processor fan is pluged into the corect port. Some boards monitor fan speed and will not boot. Double check all wires pluged into the board. Have the ram tested, or buy a 128 chip and see if it boots. Try a $16 pci video card<probly not the problem. Have the processor tested. DDR likes to be populated backwords. slot 4,3,2,1 No beeps check the onboard speaker conection. then probly the ram, processor, mainboard. w/ nothing else attached. execpt video, and fans. |
Yes I swapped the Power Supply thinking the voltage regulator was off. CPU Fan is in the right place. Don't know if the speaker works or not, but since nothing goes to the monitor, I figure the speaker works and the computer doesn't. I have disconnected everything but video and fans and still no joy. I'll swap the RAM around and see what happens. NADA Guess I'll scrounge a new video and see what happens |
Is this an AGP video card, or PCI? If AGP, check the jumper settings for the AGP chipset. If it's an older AGP card (2X) and the jumpers are set for something else, this could be the problem. |

I quickly scanned the text so if this is a dupe sorry! You say drives as in multiple drives....How are they configured? Master and Slave cable select? Are they on the same IDE ribbon? Try setting one to Master, and connecting to IDE ribbon #1. Sounds like there is a conflict when the hard drives(s) are trying to boot. This mis-configuration won't trigger any POST "beeps" My .02 |

I was a tech for many years, CPUs failing are rare. More likely to be the motherboard. Ever use the case before? Disconnnect the power button connector and try shorting the jumper post with a screwdriver. (Don't worry that's all a switch does.) I think those Intel boards have an LED on the board to indicate there is power to it. It's lit as long as the system is plugged in to AC - computer on or off. When you unplug the AC the led should fade out in 5-10 seconds. |
