Dell Dimension 2400 won't turn on

My Dell wont turn on.  The button on the front of the tower will turn red for a very short time when I push it, but the computer won't come on.  The monitor works fine and I've tried a different cord and tested the outlet the tower is plugged into.  Someone told me to buy a new power supply, but I think it might just be the button on the front of the tower.  I pulled the unit apart and carefully dusted everything and cleaned the contact point where is the button hits the switch on the inside.  Is there a way I can test the button, or should I just buy a new power supply?  Any help you can offer would be appreciated.  Thank you

    Dell XW8200 Server. Fans inop front panel red light blinks 3 times on power up. No DC voltage present on PS adapters. Replaced PS problem remains. Suspect Grounding or PS return problem but cannot confirm.

    Before you do this, locate the A B C D lights in the back of your computer. When you try to turn on the computer please let us know if any or all light up druing that short period.

SOURCE: optiplex 170l motherboard to fit

Both systems use a Mitac Chassis, only real difference is the front bezel.

So one motherboard should fit the other.

SOURCE: how do you open the tower of a dimension 2400

If you look at the CPU from the back. On one side usually the left you will see a screw where the side wraps around the back. Some brands will use two screws. Remove this screw and then you can slide the side panel back toward yourself. Then you can turn the CPU exposing the open side. While your in there (make sure the unit is not plugged in) take a can of compressed air and clean your cooling fans and vents. Keeping a computer cool is important to keeping good performance up to where it should be.

SOURCE: My Dell dimension 2400 monitor doesn't work when

Hi! For dell machines when u unplug the video cable/VGA from the tower while the system is on it will show monitor self test.If you are seeing a black box moving around the screen it means that monitor is ok.Check connection between monitor and tower.Make sure cables are securely plugged in.Check if the tower is ok. There is a possibility that your monitor is ok but the tower is not.check the power button (whats the color) if amber/orange, this means there is something wrong the the tower. If its blue or white it means its ok.Also check if you are going to hear one beep, it means system is booting up properly. If tower is ok and you are using a expansion video card then try to use internal one, normally its the vga port above the usbs.If you are going to use onboard video card make sure you enable it first in bios.If all things fail, contact your manufacturer, if the system is under warranty then they will send a tech to check the machine.hope this helps...

Open up your tower and take out the ram. Then put it back in and close the case. Make sure your power cord is disconnected when you do it. Then restart and see if it helps.

The power supply is receiving power from the source but is unable to properly distribute it to the components. This means that either your power supply is bad or the motherboard. Try removing all devices attached to your computer and check your USB ports to see if they are damaged.

My dell dimension 2400 goes on standby automatically.


If the power LED on the Tower is blinking amber, then most likely the power supply in the tower is failing. Replace the power supply.

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
