Hi,
Is there any chance for you to check if the power supply blows air from inside of the power supply? If yes, on your motherboard, do disconnect the P1 cable or the main power supply cable that connects to the motherboard and the P2 cable which. and try to plug the power cord of the power supply and if the fan did not spin, power supply is the one causing the problem

You may also try to remove the RAM or memory card module from the motherboard and all of the PCI card connected to the motherboard. Try to turn on the system and check the power supply fan and the CPU fan if it will spin. If not then I recommend you to replace the power supply.

On the other hand, if the fan is spinning on the power supply after you remove all the RAM and PCI cards. And the power button light is flashing amber or solid amber color. Try to install RAM 1 by 1 to isolate the problem.

Let me know if the problem persist

SOURCE: dell diminsion 4700c . how to figure if power suply is burt? or something else

I just fixed a Dell 4700c with this exact same problem and it was the power supply. Also on Dells website they say that a flashing yellow light is a power issue. They suggest checking all your power connections. You can also unplug all the power cables to your drives just to make sure it isn't one of the drives that's gone bad and keeping it from starting. While this is highly unlikely I have seen it before.

If you have access to an atx power supply, you can do what I did. Just plug in the new power supply and see if it boots up. You don't have to remove the other power supply to do this. Just plug in the 2 power cables that go to the motherboard, no need to plug in any of the cables to the drives.

SOURCE: Swap Dell 4700C Motherboard into New Case

Let's make this really simple, though you are apparently knowledgeable enough to realize the answer,
without my intervention.

Knowing what we both know about the units and their present condition.
1. The 2400's board is dead.
2. The 4700C's network card and CD Drive (hence, the slots and/or inputs on the motherboard, and
therefore the motherboard are also dead.) I am willing to bet you that in another system, the network
card and CD actually work.
3. All Dell® system's are totally proprietary in the board design and even the placement and removal
procedures for all drives.
4. Neither system is state-of-the art, but you knew that also.

ergo

Since you know enough to protect for ESD I will take a shot and acknowledge that you could build from
a barebones kit a new unit, using any of the parts from the two systems that actually work and end up
with a brand new system that will work for you for an extended time period into the future.

I have dell dimension 4700c I just get black screen all diagnostic light are green there are on beeps I have try F2,F8,F12,Windows turn it on take power cord out nothing is working pleas ehelp


You should try a different monitor if you can. I can't tell if you see the motherboard's BIOS, but if you don't, then I bet it's the monitor. If you can't find another monitor to plug it into, your TV might have the correct input. Hope this helps!

Motherboard driver for dell 4700c


You can download the drivers from Dell WEB site, the support download page. Make sure you select your model desktop or laptop, better still, type in the Service Tag number, it is printed on the label on the bottom of the laptop and on the back or sides of a desktop. (If the Service Tag label is missing then go into the BIOS setting and on one of the BIOS pages, the Service Tag number will be displayed). This will open the page where the specific drivers for your model computer are located. Also make sure you select the Windows XP or Vista version of the drivers for your Windows operating system. Click on this link to download the drivers: -

Swap Dell 4700C Motherboard into New Case


As long as the form factors are the same ie ATX then it should be fine - also ensure that cooling will be fine and that hardware wise it will all fit in then it should be fine if either of them are under warranty then I would check with Dell.

what things do you need to plug in as a network card only takes up one PCI slot, a dvd rw drive replacement is cheap and can either be IDE or SATA so dont see how that would take up extra space in terms of slots ?

If you need more IDE or SATA slots you can get another PCI card to support that / them.

My Dell 4700C PC will not start


Sounds like a blown power supply. Easily fixed. Go the a local computer store and buy a 400+ watt power supply, open your case, remove the 4 screws in the back, all the power plugs and replace with the new one.
