Dell Dimension 8100. No start!

I have an dimension 8100. When I push start a yellow light comes on on the mother board, the cooling fan turns, and a series of five beeps followed by two beeps then two beeps and finally one beep. That is where it ends. Never starts.

The exact beep code for that machine means that you are using unsupported RAM.

This Dell computer uses RAMBUS memory (aka RDRAM / RIMM)... not DDR or DDR2 /DIMM

Try this:
Use only one memory module (the oldest one if you added any).
It will work with no problems.
ok, replace that module with the largest capacity (1GB??) or with the newest module. May not work consistently...
Check with Dell website to determine what brand RAM is supported on that machine.
or purchase RAM directly from Dell.

Look on the back of the case where the devices plug into it. There will be a set of 4 led lights. starting from the top down oe left to right depending on how they are situated, look at the lights and this is a doagostic of what is happening during the boot sequence. These are green and yellow lights and their order and color are the signifigance of what is wrong, if you have your manual, the meaning of the colors is in there under troubleshooting. I'll see if I can find it......check this out

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes P
c

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

You probably need a new motherboard as this can mean that your CPU is fried or just the motherboard is shot (5 beeps). I would try removing the RAM from the motherboard and re-seating it.

Power supply or motherboard dell 4600


Ok, you stated that the power supply cooling fan was running at this time. unfortunately, this is not the power supply unit that has failed. the mother board has actually failed in this case. If the power unit was damaged, the cooling fan would not spin. You will need tp replace the mother board in this case. it has failed.

This is not a novice situation. we recommend a service tech for this type of repair. if it was a power supply issue, it would have been quite easy to replace but, this is not the issue here. it the mother board.

Yellow light on dell dimension 2400 and it won't work


HI, this is signaling an issue that is concerning the power unit(power supply). this can also be an issue with the mother board as well. you can confirm the actual issue by, inspecting the cooling fan that is on the power unit. if the power unit fan is not running when you push the power button to power up the PC, replace the power supply. if the fan is running, replace the mother board.

Sounds like the power supply is faulting. If not it is your mother board that has failed.

Pover up trouble


sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?
