How old is this machine? It sounds like a power supply issue. If you have a different PC you could try and swap power sypplies.

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.

Dell Dimension 3100 desktop computer?
An Intel Pentium 4.

Intel Pentium 4 model 640.
Can operate up to a frequency rate of 3.2GigaHertz. (3.2GHz)
Fits in a Socket 775 processor socket. (Also know as Socket T)

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_2M_.2890.C2.A0nm.29

Can use up to 84 Watts.


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).

Working on dell dimension 3100/e310 desktop pc. when u press the power button u get a soid green light with beeps and the diagnostic light are green on lights numbered 3 and 4. need help badly


Constant beeping on power up can be a memory issue.

Locate the memory module and reseat it by taking it out and putting it back. Do this with the battery and power adaptor out. The module is normally located under a cover on the base of the computer.

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.

No power up no post no nothing on dimension 3100


An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. It sounds like you have isolated the problem to the motherboard since you removed everything but the board and power supply. You may be able to locate one by browsing the internet. Just type in “DELL Dimension 3100 motherboard” and see if you can locate one at a reasonable price.
