My system worked properly previously. I uninstalled some programs in Add/Remove programs in control panel. After that, my system felt very difficult to show the DVD videos. I got an idea to reduce my hardware acceleration in the display properties with the help of Trouble shooting. After i reduced my hardware acceleration to low, my system got restarted. Now it doesnot showing anything after the XP logo. But it is logging in the background.

one thing that you can do is turn on the auto login feature if the screen goes blank or the login session times out. I am not aware of any reason why the system would time out. The auto login setting will log you in in the event your screen goes blank.
Check if the cable connecting your monitor from the video card is properly secure and not loose... You can also try this... turn off your cpu..remove the cable from your video card.....Open the housing....remove your video card from your motherboard... clean the contact surface of the video card with moisten cloth.... after cleaning...connect the video card to the motherboard...attached the cable to your video card.. close the housing and try to boot again...
I hope that work.. if not my suggestion is you try your video card in other computer, try also the monitor to other computer.. to see which one failed.
did u replace the video card with the same kind of model ? i guess yes ... when system starts hit the f8 key and than go in to safe mode ... mouse wont work so use arrow on the keyboard .. and in the safe mode just log in to admin account if available or login to ur account and see if that still happens .. and if it doesnt ... remove the drivers for the graphic card from add and remove programs and restart the system and go in the normal mode and than install the drivers again ... and if the display disappears in the safe mode or u have install a different graphic card than ... reseat the memory cards and that should resolve the issue .... if that doesnt work out when the system starts hit f1 and stay on the BIOS screen for 30 mins if the system doesnt loose display than u need to reinstall OS ... that will surely work out ... the resolutions given above if u follow them correctly u will have a working system in no time
Self-Test Feature Check (STFC)
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Turn off both your computer and the monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
Turn on the monitor.
The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
It appears that the display resolution set in your display properties is out of the range that the LCD can display.
Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
