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.

My dell dimension 3100 is not coming on it just blinking orange light


No bleeping sound? Then I would say that your RAM is no good.
If the coolers don't run I'm afraid that the processor is faulty.
Any more I cannot tell you right now, sorry.

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

When i start up my dimension 3100 dell desktop instead of a green light i get a flashing amber light. people say it is the power supply but the light wouldnt even come on if it was. can you please help me?


No, the light WOULD come on if it was a Power Supply problem.

1) If ALL of the LED lights on your computer were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor uses from 51 to 125 Watts. Depends on what Processor it is.

You have enough power to light that LED light, but not enough power to turn the Processor on.

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).

Computer not coming on


Flashing Amber Light on a Dell Desktop is a defective power supply.
You can get a replacement from various vendors, or Dell.
Good Luck.
