Black screen - no flashing white cursor in the upper left corner - no picture at all, i.e. the initial Dell start-up screen doesn't show up either:
- LCD is dead or isn't getting a signal - not an easy fix; or
- the LCD isn't being sent a signal - holding down the function [Fn] key and press display Function key to toggle through its settings (LCD panel only, Rear VGA output only, both LCD and VGA output)
Black screen - flashing white cursor in the upper left corner - the screen goes black after the windows loading screens come up but before the windows login screen comes up - it is probably a windows video driver problem. Try starting in Windows Safe Mode with VGA. Press [F8] after the Dell startup screen disappears to access the windows startup menu
1 - You may need to roll back system with System Restore. Under Safe Mode (press F8 during boot and choose safe mode). Win 7 - Start > Search type System Restore XP - Is Start > All Programs > Accessories > System Restore. Now choose a date prior to problem. You may have to try a few dates.
2 - Try disabling startup programs. Go to Start > Run (search in Win 7) and type MSConfig. Startup tab and uncheck anything that you don't want Windows to load automatically. It will make Windows boot faster and use less resources while running. This just disables them in startup. Programs will still load, but when only you initiate.
WUAUCLT -- Windows Update Automatic Update client
somehow has "crashed". It runs everytime that you restart Windows. It connects to Microsoft to look for the latest Security Updates to keep your computer protected and up-to-date.
Start Internet Explorer.
Click 'TOOLS' and click 'WINDOWS UPDATE'.
Does this version of WINDOWS UPDATE run properly?
Assuming you are using Windows XP. There's some file corrupt or missing when you start your pc. If you have floopy disk you can boot disk, it not your can insert your Windows XP installer and then you can repair you OS.
