Do you have video while booting BEFORE Windows is supposed to start to load?

"yes aftrer that the screen goes blank."

Blank as in all black or all white ?

If all black, there's likely nothing wrong with your video adapter (it may or may not be a card).

Try this.

Remove any bootable CD you have in a drive.
Press F8 repeatedly while booting the computer, don't hold down the key, and when the boot choices list appears, choose Enable VGA mode.
That mode boots Windows normally, except it forces Windows to use default VGA drivers rather than specific video drivers.
If that gets you to the desktop screen - the video will be more basic - then you need to tell Windows what type of monitor you have because the video drivers loaded in normal mode are not doing that correctly e.g. at least, Plug and Play Monitor.
RIGHT click on a blank part of the main desktop screen - Properties - Settings - Advanced - Monitor - Properties - Driver - Update Driver - No, not at this time, Next , Install from a list..., Next , Don't search..., Next
- if Plug and Play Monitor, or the exact model of your monitor, is listed, choose that, Next, etc.

or - recommended if you have an LCD monitor - click on Have Disk if you have the CD that came with the monitor, insert the CD, or if you have the proper monitor drivers download for the model go to where that is - Windows is looking for an *.inf file about the monitor, etc., etc. .

Click on Finish at the bottom of the last window, click on Close on the monitor drivers window, click on OK on the bottom of the Monitor window, click on OK on the bottom of the Display Properties window.

Restart Windows and boot normally. You should have video in Windows.
If you don't, your video drivers may be corrupted. Go into Enable VGA mode again, search for support for your exact computer model on the Dell site by using your Service Tag number (see below) - download the video drivers.
Go to Control Panel - Add Remove Programs - Uninstall the present video drivers. Reboot normally.
DO NOT install video drivers while booting the computer. Let the desktop screen load, then run the video software installation download.
Reboot.
You should have video in Windows when you boot normally. If not, go into Enable VGA mode again, load at least the Plug and Play Monitor drivers, as above.

If Enable VGA mode doesn't get you to the desktop screen, try pressing F8 while booting, then choose Safe mode.
Safe mode also forces Windows to use default VGA drivers rather than specific video drivers, but it does not load some things that are loaded when you boot Windows normally. .
If that gets you to the desktop screen - the video will be more basic - something that is not loaded in Safe mode that is loaded when you boot Windows normally is out of whack.

This series can have three different types of cases, three different mboards.
All the mboards have both onboard video and an AGP slot, so you may or may not have an AGP video card in the AGP slot.

We need your Service Tag number.

Click on "How do I find my Service Tag" here:
http://support.dell.com/support/dow...

Tell us what it is.

You can use that Service Tag number on the Dell site to find the software and drivers for your exact model, rather than all the downloads available for the whole series.

It's possible your power supply is failing.

What type and physical size of power supply you have depends on the type of computer case you have.
http://support.dell.com/support/edo...

The Small Form-Factor Computer (a skinny tower) and
Small Desktop Computer (horizontal) cases have an oddball shaped and smaller than standard sized power supply. That can only be replaced with the same shape and physical size of power supply.

The Small Mini-Tower Computer (a short tower, regular width) case uses a standard (PS/2) sized power supply. That can be replaced with any decent standard sized power supply of the same capacity or greater.

- all three -

Is the monitor connected to the onboard video port shown in blue there ,or to a video port in a card slot, 2 there ?

If there is an AGP video card in a card slot, make sure it's all the way down in it's slot.

If there is an AGP video card in a card slot, make sure it's all the way down in it's slot.
.....

If there is an an AGP video card in a card slot, the onboard video is probably automatically disabled by the bios - the onboard video port will not produce video.

You press F8 then select ENABLE VGA mode

"then it ask me to select OS to start Window Home edition is highlighted ..."

That's normal, if there is only ONE listed.

If that doesn't get you to the desktop screen, see Response 6 again - try holding in the power button until the computer shuts off, then press F8 while booting again, select Safe mode. Etc. Etc.

If that doesn't work, see the rest of response 6 - you have something else wrong.

"....when i select it then it take me to Hardware Profile /Configuration Recovery menu,it give me two option profile and test i have pick both (not at the same time)."

That's not something you normally see.

"Then Windows XP reboot up and the screen is blank and black.

It sounds like Windows just plain isn't working properly.

If there's nothing wrong with your ram or hard or optical drive, you'll probably need to run a Repair Installation of Windows - if that doesn't work, you'll have to re-load Windows from scratch.
