Do you see anything? No "ghost image"? A white cursor in the top left? Any damage ? Drop? Jarred? Bumped? May be backlighting, inverter, lose ribbon cable, bad graphic adapter. Can you attach a external monitor to verify the graphics adapter? Take a look at this video for ideas: http://www.youtube.com/watch?v=2Yi6GNFcP3w Remove ALL media from DVD rom, usb, etc. shut down, unplug, remove battery, plug in, reboot. Any change?

Tip

Applying the settings to the logon desktop


Next, you need to apply the Screensaver settings to the Logon Desktop / Welcome Screen (Technically, HKEY_USERS\.Default registry key), so that the Screensaver is invoked when no user is logged on. Copying all the Screensaver settings to the Logon Desktop (or Welcome Screen) manually is a tough task. Use Tweak UI instead.
Download and install TweakUI.
Launch TweakUI and click Logon, click Settings.
Select Screensaver from the list box and choose Copy Now
The Screensaver settings are applied to the Logon Desktop
Restart Windows for the changes to take effect
Allow few minutes at the Logon screen, to test if the Screensaver is working properly. The Screensaver should launch after the timeout. It will look as if the Company Logo moves around.
Additional Tip
The User interface / slider allows the minimum value for picture change interval to 6 seconds only. To reduce the change interval to less than 6 seconds, alter the registry value named ChangeInterval (Set decimal value 1000 for 1 Second, and so forth) in this key:
HKEY_USERS \ .DEFAULT \ Control Panel \ Screen Saver.Slideshow
For Current user profile, make the change here:
HKEY_CURRENT_USER \ Control Panel \ Screen Saver.Slideshow

With no logon wallpaper set, Windows displays a pre-defined color for the logon desktop. ( If you have enabled Welcome Screen, press CTRL+ALT+DEL twice to see the logon screen background color. ) To change the logon background color to that of your choice, you need to alter the registry:
Click Start, Run and type REGEDIT and press Enter
Navigate to the following key:
HKEY_USERS\.DEFAULT\Control Panel\Colors
Backup the registry key by exporting to a REG file
In the right pane, double-click Background
In the Edit String dialog box, type the Color code in R G B format and then click OK.
Example: Type 0 0 0 if you want to see a Black background. You can choose any combination from 0-255
Points to ponder
If the logon Wallpaper is set, the background Color may not be visible. So, you must reset the Wallpaper value to a blank string in this key: HKEY_USERS\.DEFAULT\Control Panel\Desktop
If the Background value is set under the following Winlogon registry key, the above setting is ignored. In other words, the Winlogon\Background value takes precedence over the .DEFAULT..\Background value.
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

Password


is this a bios password (you enter on a black screen with white writing) or your windows logon password.

If its your windows logon reboot, and before the windows logo appears hold F8 for safe mode. at the logon prompt clear the user and type Administrator for the use and leave the password blank. From there you can go to the control panel and clear the user's password.

Go into your BIOS
Set the 1st Boot device preference to CD
Insert your windows XP disk
Boot from CD

You do this at your own risk. I am in no way accountable for damage to your computer.

Logon


Can you describe the issue ion more detail?
Do you see a startup screen with the Windows Logo? Does the logon screen come up? Does the computer get out of the BIOS startup?
