I would put my money on the Graphics card.. If you have an old Graphics card or your pal has one then try installing it and see if it resolves the issue. Otherwise there's a problem with the motherboard as many other experts have suggested.. Postback if you need more help.

Regards,
Sai.

Disconnect all external devices (usb etc) from your machine and see if starts.
You need to open your machine, If the CPU fan if not running try unplugging and plugging it back. If it did not help replace CPU fan, the fan starts even with faulty MB then is either CPU fan or Motherboard.

If CPU is fine try doing the same with RAM.
If it did not help disconnect all internal devices (disks etc) and start machine only with mother board, cpu, fan and RAM, check it it does boot.
Check warranty terms, Dell gives you always one year guaranty.

Hello sig,

if a light comes on, that means it is reciving electricity.

The orange light you mention, is turned on the whole time, or only when you try turn on your computer?

Have you recently added a new hardware to your computer? like a new graphic card, or extra RAM memory?

Please answer me the following question to further help you.

Hello,

If the the fan is not working, surely there is no power input to output the pc and boot.

Please check the power supply if it working.

    Please check also the memory sometimes due to memory dumps preventing the unit not to start. please remove the memory and clean and fix it again.



    If the system still power in the monitor and in the board most likely the processor need to be check.



    first check the memory, then the motherboard. if the fan is not working in the motherboard then u have to check the board.

Hi,

If the unit is still under warranty, ask for service or replacement.

If not and you are considering a DIY (do-it-yourself), then open the unit and give special attention to the motherboard. look for any sign of corrosion, bulged or leaking capacitor or anything out of the ordinary. Another are to check closely would be the front USB ports.

Incidentally, Dell has posted a service manual here.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    It is either the motherboard (most likely) or the processor (possibly) or both.

Sounds like your machine is in hibernation. Normally, the mouse being moved or pressing any key should wake it up but that doesn't always work.

At the back should be a rocker switch. Turn the PC off from there and wait a minute, then turn the rocker panel on again and press Power to start if it doesn't start on its own.

If this doesn't do it for you post back using the ocmment box below and use my initials (WV) to address my solution. Same with others

Regards,
Worldvet

Could be an overheating problem.

Power it off & disconnect the power. Open up the case, and use a vacuum cleaner, canned air, QTip, and be sure all dust is gone from the fans, vents, and other openings.

You may need to do this on a regular (monthly or so) basis, especially if you have pets, as I do. Also, consider getting the computer up off the floor if you can, and make sure it gets good airflow.

Something I've seen occasionally on Dell boxes is that they'll have problems booting up or shutting down if a USB device is attached to them (not the keyboard or mouse, but a flash drive, USB hub, or similar.)

If that applies to you, disconnect the devices to get it to boot. Then, add one device at a time, shutting down and starting up again. You might determine which is the offender, and see if there are new drivers available.

I had a Logitech device that cause a problem. I removed their drivers, and Windows loaded it's own, and the problem went away.

Hope that helps.

Dell dimension 3100 restarting


This is generally an indication of boot failure , often as a result of new hardware addition or new software installation. Try pressing the F8 key repeatedly (about once per second) while booting and boot in safe mode. If no success , try removing any hardware (especially flash drives) that was added since the last time the machine worked and try the above again

Blinking orange light


Last two times I had that with Dell desktops, they were older machines with main board failure. Writeoff. If you don't get any fan activity or other signs of life, it may be main board problems.

Dimension 3100 turns on the power button has a steady orange light there is also an orange light on motherboard cpu and power suplly fans working but wont bot up


Blinking amber (orange) indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this could indicate a problem with the power connections for the CPU on the system board (see "Power Problems" in your Owner's Manual).
