I am moving the motherboard to another case that ATX and AT motherboard compatible; but, I need to know how to hook-up the cases front light, sound, external USB, power switch and indicator light etc., Therefore, I need to know where on the motherboard to hook-up the above listed items

So you have a case with front connections and no place to hook those up? You will have to get a different case, that is a nice motherboard.

This may sound simple, but make sure the monitor is set to correct input. Many are auto detect, but you never really know.

You could also check BIOS for onboard video. Disable if you have an add-on video card. Enable if you don't

Reseat the video card if it an add-on.

you can go to newegg.com
search for a MATX motherboard.
you can go AMD or Intel depending on how much money you can afford.

depends on the case that it is in. for the physical size. but normally any ATX power supply of 350watts or better is a good selection.
i need a picture of the case to be sure

Two possible causes - either you have installed it badly and it shorts to the case (take it out of the case and try it there) or not all the necessary cables were connected (check especially the power cables and the power button).

The difference between ATX and MicroATX is the size. An ATX board will usually have 6-7 slots to add cards like video, network or sound cards. An ATX board will also usually not have a video port on the board. A MicroATX board will usually have only 3-4 slots to add cards into it, at least one of which being dedicated to AGP or PCI Express Video cards.
To answer your question: That computer uses a MicroATX board. A Micro ATX board will most likely work in any PC Case whereas an ATX board requires an ATX size case (Mid or Full size Tower).

I assume you mean the HDD,reset,on switch etc where they plug onto the mobo.

Most mobos are labelled on the board but you will need good eyesight to read. They are labelled HDD, RESET, SPEAKER etc.

If not simply look up mobo manual from vendors site. You will need the DELL serial / part number from the old unit though.

The front audio in this case does not support HD sound. To get it to work you must instal the "HD Sound Application" that came with your hardware and disable the "Detect Front Panel Jack Detection" option. You'll have to manually switch between the two inputs.

Actually it could be the battery. They are not as good as they used to be. As for the motherboard you would need to know what your case could support. There is ATX, micro ATX, E-ATX, & BTX motherboards. It all depends on the case. Hope this helps.

You need a separate cable, called a USB header. It plugs to the connector in the case and onto your motherboard. A lot harder to find that you would think too, my top ports still are not hooked up after several years.
