Dimension 4400 will not boot diag D lit amber all others green

  • Hi,
    I have a Dell dimension 4400 diagnostic lights are GGGY they go to that at switch on.
    Have removed all PCI cards and unplugged all IDE cables no change. Video card works on other computer, removed memory and it bleeps 3 times. Tech support said faulty video card, monitor says no signal if unplug monitor no connection.
     
    Any ideas what to do next
  • propforward,

    The GGGY indicates that the system posted but did not finish booting to the OS.  See if the system can boot to something other than Windows.  Put in a DOS disk and see if it boots.  If it boots to a DOS disk, then the problem is with the hard drive or with the OS itself. 

    You can see if the problem is with the hard drive by pressing Ctrl-Alt-D when the Dell BIOS logo is visible.  This will run the built in hard drive diags.  If the test does not pass, then the hdd needs to be replaced.  If the test passes, then the OS will most likely need to be reinstalled.

  • the display is blank I have tried a different HDD and the 4400 just goes to GGGY have tried unplugging all cables removing the battery.

    Could it be the cpu or mobo?

  • propforward,

    It could be the motherboard.  Have you tried to boot to a floppy disk to see if the system will boot to something other than a hard drive?  You can download a bootable DOS disk image from this link:

  • will not boot to dos disk or windows xp cd. Cannot see anything on display.
  • propforward,

    Q1.  When you try to boot to the DOS disk, what color are the diag lights on the back of the computer? 

    Q2.  Is the power LED lit on the monitor?  What color?

  • Hi Steve,

    Q1.  When you try to boot to the DOS disk, what color are the diag lights on the back of the computer? 

    the lights stay GGGY as soon as power applied straight to this state. The HDD light on the front of the machine lights for a short period then stop.
     

    Q2.  Is the power LED lit on the monitor?  What color?

    the led on the monitor is Green, if you turn the monitor off then on it shows "no signal" if you unplug the monitor cable changes to "no connection".

    I have tried the monitor and video card in my PC and both work fine.

  • Try to reseat your  memory and cmos battery and checked if your PC will be able to turn on.
  • propforward,
     
    If the diag lights are GGGY immediately upon starting the computer and do not cycle through any other patterns at all, then either the motherboard has failed or the processor has failed.  If the diag lights cycle through other patterns before settling on this pattern, and will not boot to anything at all, then the motherboard has most likely failed.  It is possible that the fault is with one of the drives itself and is shorting out one of the power outputs from the power supply.  Disconnect all hard drives and CD drives (data and power connectors) and then try to boot to a floppy disk.
