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.

Dell 3100 will not power up


Hardware issues: (most likely the motherboard)

Start by removing:
Ram Chip one by one. See if it will change anything (if it doesn't put that back in)
Cd Drive
Hard drive
Anything else (video card, PCI components)

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).

Blinking amber light and wont boot up.


if the power button was blinking amber, unplug your tower, and hold the power button for 30 seconds to 1 minute, to use any excess power stored in the capassitors in the pc. this was told to me by a dell tech, it is a small issue with the 3100=E310, and 5150=E510 Dimension desktops

You need to listen carefully to those beeps they will tellyou in a moment where to start looking for any problem

They are listed in your manual but if you dont have that then they re listed on the dell websiteunder the support section Q and A.
