    I'll give it a try and let you know how it went...Thanks..!

  • LatinHeat88 Oct 07, 2007

    by the way it's only 1 beep that repeats..!

  • LatinHeat88 Oct 08, 2007

    ok I tried your cleaning recomendation and still had the same problem. before trying to do the CMOS reset I desided to change the memory, from 400 to 333. this seems to have solved the problem -in parts- now the system keeps cycling to the safe mood- last good config- etc. screen. but no matter what my selection after post the same screen..
    could it be a defective HD..?

    Elitegroup 755-A2 motherboard
    AMD Sempron 3100+ processor
    1GB of RAM (333MHz, I think...)
    AGP GeForce FX 5200 256Mb graphics
    DVD RW (IDE1 master - tried system with and without this)
    1 Maxtor 60GB IDE HD (IDE0 slave - LINUX)
    1 Maxtor 120GB IDE HD (IDEo master boot - XP)
    Dual boot XP and DEBIAN Etch x86

    The problem started when I tried to plug in a case fan and a HD cooling fan to the system - the next boot up caused the system to sound three short beeps and the power button light to flash on and of at about 60 flashes per second. The HD light is off.

    I can press the power button whilst the PC is in this state and the boot commences. At some point it either freezes or reboots itself automatically - sometimes at drive check, and more often when XP is logging in (just after splash or when asking for the user account).

    Another symptom is when the computer makes a longer beep intemittently with the HD light constantly on, and no activity at all from the system - similar to 'LatinHeat88'. Nothing appears on the screen. The PC needs a hard power-off (holding the power button).

    What is the problem?

  • LatinHeat88 Nov 14, 2007


    I solved the issue long ago. I formatted a small 20GB HD that I keep around to help trouble shoot. Once I saw that everything was runnig, I figured out the XP was running "Blind" (as you put it) and ran a repair then a reinstall of the OS. Problem solved.! And I didn't lose one bit of information.. I wish I had your solution sooner it would have save me a lot of time, but then again running into trouble and finding your way out -no matter how tideous- can be exactly what one needs from time to time. It helps you learn and share your solutions with others.. Thanks Buddy..!

Okay - A little focus and resolve and the answer seems to be:

To get the system running again...

-unplug all unessential components
[I left my CPU, CPUfan, GPU, GPUfan, memory, both HDs connected inside; keyboard, monitor outside; USB mouse on standby]
-reset CMOS
[a matter of power-down, move jumper, move jumper back after a few moments]
-reboot and enter BIOS, reset date
[if date is not reset then checks may be enforced - DEBIAN Etch will do this!]
-plug in mouse

I have still to find out the cause for the problem in the first place, so as soon as I have all my backups off the drive I will try plugging in the DVD-RW, and each extra fan in turn. I have a suspicion that there is an overload problem (the PSU is rated 500W; I have to ask is this enough?).

Hi, Depends on the number of beeps and their sequence, the problem can either be video or memory. In some rare instances (Asus motherboards) this would indicate a BIOS problem. Perhaps what you try is to remove the video card/memory, clean the gold contacts using a pencil eraser and re-insert back to the slot. You can also try doing a CMOS reset on the motherboard and thereafter run it a Fail-Safe or Default settings. Hope this be of some help/idea. Post back how things turns up or should you need additional information. Good luck and kind regards.

    On motherboards with built-in video, the memory is shared.

    Hi Gil,

    Re your last post "could it be a defective HD..?"

    Either that or that HD came from another system/setup and the OS no longer recognizes the motherboard. On install, XP binds itself to the motherboard config/specs. Transferring HD from one system to another of different model would cause Windows boot looping in any mode.

    You can try re-install using the "Repair" option but perhaps your best route would be to re-install clean/fresh/new the OS.

Probably windows picked the wrong drivers, if it was microsofts download. Try to get to safe mode and type restore point in the search box. Select a date prior to the update. If it was a windows update there will be a restore point set.

Dryer appears to 'overheat'...starts a load but stops before finishing then won't start again for hours...

Test air flow. Remove the exhaust hose at the rear of the dryer, run the dryer and form an opinion on the volume of air flow, hook the hose back up, turn on dryer again and verify that the same volume of air exits the building. Usually a build up is the cause of your complaint.

When boot up i get 1 long and 2 short beep repeatedly. No additional hardware attach to mobo. Please advise

Thats a video card failure.

If the video card is build into the mainboard try attaching a another videocard to the motherboard and see if it boots up

I know the beeping too well, I've had that happen on laptops and well a few desktops, if the new card doesn't solve the problem the mainboard is faulty.

New build computer boot problem

The exact problem is not actually a problem.Just get in to BIOS.
As it is a new system, even if you get to boot from HDD it would say insert proper boot device and press enter or your floppy drive is in first boot.Check you boot settings.

Change the boot order as below.
  • 1st boot device:CD drive
  • 2nd boot device:Hard drive
  • 3rd boot device: anything you want
Now save and exit(F10 then Enter)
Now your PC will reboot.

Drop in the OS CD (Xp , LINUX or whatever)
Install the OS .Now you are ready to use your PC.

Failed POST

Foxconn uses the Award bios. One beep repeating means, check for improperly seated or missing memory. You can find that here.
Remove your memory & re-seat.

Good luck!
