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.

My dell 4600c monitor will only show a picture when i start or restart it with the monitor power button. it is only on for about 1.5 seconds each time.


If the tower power LED is a Steady Green and the Diagnostic LEDs on the Back are all Green then the monitor itself appears to be the failure point. See if issue occurs with a different monitor. If the tower LEDs are not all green, then reply with the indications

If you reformatted the hard drive, you have erased everything. If you have restore or backup disks use them now.

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.

Dell wont start up


On the back of the chassis, there are 4 LEDs above the PS2 connections marked ABCD what do they indicate? During the boot process the lights normally flash on and off green, when the boot process is complete, they should all be green GGGG.

If any are Amber then they are indicating a power on self test (POST) failure. AAGG is bad memory for example.

Post the indications

Dell 3100 no coming on


Did you checked whether the CPU / tower is turned on.. press some keys on your keyboard to make it active.

This might looks funny but it works all the time :)

Cannot get any sound from my Dimension 3100


Speakers are not built into the box itself. They may be in the monitor, or completely separate.

Did you get this directly from Dell, or from a third party. Dell would have shipped you speakers with it, or a monitor with speakers built-in. Purchased from a third-party you might just get the box itself.

If you have a monitor with speakers, you still have to connect the sound output from the box to the monitor.
