HERE is the information on removing a PCIe card or other cards in the 4700.  

Thanks for the link.  Another question -- Does the monitor cable plug into the graphics card?  If so,  it doesn't look like the picture of the cards in the manual.  It's tucked behind the fan and under another connector, like a printer connector. 

Thanks,

Yes, you must plug the monitor cable into the video card or it won't work.  It will need to plug into the VGA (blue) or DVI (white) connector on the video card depending on your monitor type.  If they monitor cable is plugged into the blue VGA connector below the power supply fan, then you have it connected to your integrated graphics not the video card which is located down low on the back of the case.  

Yelp,  I plug the monitor cable into the blue connector.  Sounds like that's the little thingy I need to remove/replace.  Problem is, the  instruction manual doesn't tell me how to remove it. Can it be removed?   I hate to spend money on this computer but it has a lot of digital pictures stored on it. 

Thanks, 

You cannot remove it.  If for some reason your video card is not working, then you just need to make sure that it is detecting the card correctly in the BIOS (use F2 at start up to enter system setup) and make the necessary changes if not.  You can also disable the onboard graphics through the Device Manager if it is still not working. Now, to be clear, do you have a dedicated PCI Express X16 video card?  

Here is a picture of the back of a 4700 computer.  As you can see, the onboard graphics is below the green connector and next to the red or pink one and cannot be physically removed.  Also, you can see that this computer does have a dedicated graphics card which is in the PCIe X16 slot below all the other connectors/fan and has both  DVI and VGA with an S Video connector in the middle of it.  If you do not have this in one of those 4 slots, then you do not have a dedicated video card.  A PCIe X16 card will always be in the top of the 4 available slots with the others being PCI and PCIe X1.  

JMichael,

Thanks for the wonderful explanation & picture.  I don't have the dedicated PCIe X16 card, only the blue integrated one.   I'm not sure my problem is the video card.  Someone suggested I remove & replace it since my symptoms began after disconnecting the monitor.  Here's my problem... computer won't boot, lights come on but no "interaction" with monitor ie.  when I press the + or - button on the monitor while waiting for it to boot, I get the message, "In power save Mode, press any key on the keyboard or mouse".

The 4 lights (ABCD) are YYGG.  I have clean out the computer, reseated the memory & all other connections. 

Thanks again for your time & patience.

YYGG indicates a memory failure.  See HERE.  

That sounds like an easy fix.  Thanks.   I removed the memory and reinstalled it without success.  Guess I need to purchase new memory.  Thanks for all your help.

 Try removing all the memory modules, then install only one module in slot 1, then see if the system boots and if the computer starts normally, reinstall an additional module.

Does not boot, move the module to slot 2 and again see if the system boots, no boot, try the module in slot 3, no boot, try installing in slot 4.

Still does not boot, then remove the first module and using the second one, repeat the sequence described above.

Still no boot, try installing any remaining modules, one at a time, using the above procedure.

Continue until you have identified a faulty module [or slot] or reinstalled all modules without error.

Thanks Bev,

I only have 1 memory module so it was pretty easy but it didn't boot.  Think I'll take a chance that it's bad memory & purchase new memory.  Keep your fingers crossed for me!

Thanks again,

You need to buy compatible RAM for the Dimension 4700.

One the best vendor's for memory is Crucial, their RAM is guaranteed to be compatible with your system, has a lifetime warranty and free S&H.

 See HERE. 

<ADMIN NOTE: Broken link has been removed from this post by Dell>

The 4700 supports DDR2 memory, for maximum performance, this memory should be installed in matching pairs.
