Hi marcellanam,
I see you need to have your BIOS unlocked.
Only dell unlock your BIOS for you call DELL and get assistance on unlocking your BIOS, you can ge that to a computer shop but it will cost you and will most likely be done in a different way and may change many things on your Dell machine.
I strongly suggest that you call Dell for the BIOS to be unlocked all you have to do is call Dell and give them the systems service TAG number so they can give you the unlock code for the BIOS.
I hope this helps.

try to remove the cover of your laptop. Then remove the motherboard battery for about 10 min. Put it again and bios should be restarted.

I had the same exact problem, Open Office was causing some weird conflict Try restoring to a time before you installed any software, makes no sense but that is what caused/cured my problem
BTW, do you get atone when you press those keys?

Dell keeps a master code for each of their machines. All you have to do is transfer ownership of the machine into your name, if it isn't already, and give tech support a call, and they'll give you the code over the phone. You can transfer ownership at Dell's support site, there a subcategory on the left of the screen that reads "ownership transfer". Here's a link for the tech support number.

If you already have an USB flas bootable with XP on it, plug in into the laptop, and when the laptop starts, press F12. Then you should select that the computer should boot from USB. If this won't work, try to attach an external DVD\cd unit.

Depends on if you still have a bios boot. U need to see while your flashing one. Dell has the flash tool on their site and a step by step follow the directions exactly and read 20 times b4 you attempt. If you have no bios boot at all then the bios chip itself has to be replaced. However you may as well buy a donor with a screen problem make the best out of 2.
