If you have no power by pressing the front power button and you have verified that the black connector coming from the power switch on the front is connected properly to the motherboard, then make sure that both connectors from the power supply are connected properly, the main connector and the p4 connector. Reseat both of the connectors to be sure.

If you still have no power and still have the light coming up on the motherboard then I think the motherboard may be bad cause that means something is shorting out the motherboard and not allowing power to go thru it properly.

Will a NVIDIA GeForce gt 610 graphics processor work on a Dell Dimension 2400 PC Desktop

YES, Zian it will work....BUT,....................

1) It is a PCI graphics card, and uses a PCI expansion slot.

The Dell Dimension 2400 Desktop PC's motherboard, has three long white PCI slots,

If one of those long white PCI slots is open, you can use a PCI graphics card.

Concerned that the graphics card uses DDR3 graphics memory, and your computer only uses DDR Sdram ram memory?

Don't be.

The graphics card has it's own processor (Graphics Processing Unit), and graphics memory.
It runs independent of the system resources; the Processor and Ram Memory.

The concern is the Power Supply.
Original power supply's maximum rated Wattage is either 200 Watts, or 250 Watts.

The above graphics card requires a minimum system requirement/power supply requirement; of 300 Watts.

I would recommend replacing the Power Supply.
(Especially with it's age, if it is still the same one)

ONE thing though..............
Watch the 20-pin ATX main power cable connector, and the wires in it. Be sure they are in the standard place setup.

Check the pinout, and color code of the wires,

1) Dell Dimension 2400 desktop computer, 20-pin ATX main power cable connector pinout,

2) STANDARD 20-pin ATX main cable connector pinout, and color code of wires; as set by JEDEC,

[Be aware that the ATX main power cable, and connector, you get with a new power supply; such as the above, will have a 20 =4-pin ATX main power cable connector,

Use the 20-pin connector, tie the 4-pin power cable up out of the way]

For a time period Dell was making the motherboard's main power cable connector - Proprietary.
Meaning they has that motherboard connector wire pinout changed.
Colors of wires were in a different place, than the standard setup by JEDEC.

Orange wires are 3.3 Volts (DC)
Red wires are 5 Volts (DC)
Yellow wires are 12 Volts (DC)
Black wires are Ground wires.

Guess what happens if a 12 Volt Yellow wire, is plugged into where a Black Ground wire is supposed to be?

ZZZZZZzzzzt! Motherboard fries, processor fries, ram memory fries, and graphics card. (If used)

Check the color code of the wires, in the 20-pin ATX main power cable's CONNECTOR, for the Dimension 2400's power supply.

Dimension 5150 constantly restarts. Our Dell will power up and restart itself prior to the Dell logo appearing (approx 2-4 seconds total uptime). We found that once it is powered up, if we removed the...


Hope this isn't too late for you.

As a matter of fact, I have a 5150 that was doing the same thing you describe. I replaced the front card as you did, along with the ribbon cable and even the power supply. After talking with a good computer guy, he agreed it was the motherboard. I got one on eBay for about $100. That was a little expensive, but it solved the problem. The computer has been up for about 3 weeks now with no problems.

You will have to decide if you think it is worth it since some new systems can be had for only $400-$500 dollars.

Hope this helps. Please take a moment to rate this solution.

I have a dell dimension 2400 with a blinking amber light what do i do

The blinking amber light on the dimesion 2400 generally means that the power supply on the system has gone bad. Switch off the system and disconnect the power cord from the back of the system . Press and hold down the power button in the front for 10 seconds.
Reconnect the cable back and try powering on the system.

If the same ,fails you would have to take the system in for repairs

I have a dell dimension 2400. My starts up fine

Most likely a motherboard issue.

Also ensure the CPU Heatsink is firmly attached. If the heatsink is loose, replace the plastic heatsink retainer

If it is secure, then the motherboard is the most likely failure point

Yellow light on dell dimension 2400 and it won't work

HI, this is signaling an issue that is concerning the power unit(power supply). this can also be an issue with the mother board as well. you can confirm the actual issue by, inspecting the cooling fan that is on the power unit. if the power unit fan is not running when you push the power button to power up the PC, replace the power supply. if the fan is running, replace the mother board.
