Try running the Dell diagnostics. Press F12 when you see the Dell Logo and choose "Boot to Utility Partition" from the Boot time menu. Once it loads up, click on Express Test and then choose Video or Graphics. Let me know what the results say.

Hi ynardz and welcome to Daniweb,
You have hijacked an old thread from Nov 3rd, 2006, if you want more information please start your own thread and sullpy a lot of information about your machine, OS and problem.

I can only guess that the resolution has automatically been reset to allow for a different size screen. That is, if the resolution was to stay the same, you would have black parts of the screen.
