Dell inspiron 6400 screen won't go 'full screen' on pinball (running XP Pro)

Before you use the Recovery CD you need to backup your data because to restoring your laptop will wipe your data off the hard disk.
To backup your data when you cannot boot up your laptop, remove the hard drive and connect it to an USB hard drive adapter. Connect this hard drive/USB adapter into the USB port of a working computer. The computer will see it as an external storage device, you can then open the folders and backup your data.
You can then fit the hard drive back into the Dell laptop and boot up with the Dell recovery CD to reinstall Windows etc.

Yes. There is an easy solution. Use the free Microsoft diagnostic scan and fix. It only requires three easy mouse clicks and Microsoft does the rest. CLICK HERE

it sounds like your display backlight has gone bad. If your handy you can get a new display. If you are really good you can replace the back light.

from above link you can download the driver..

According to the specs for this laptop it comes with Vista. Because of that I am assuming you have put XP on it in place of Vista and I am also assuming that you just need to install some additional drivers from Dell. Click Here to go to Dell's driver listing for the Inspiron 6400 and make sure Win XP is selected as the OS and download the correct Video driver.

This because the system might be running mutiple processes. Remove the programs from startup. Download ccleaner. Delete temporary files using it. Check whether disk defragmantation is required

Install The Driver For Your Computer.

Sounds like you are having a boot issue with the hard drive.

Try booting to your XP CD from the F12 menu and running CHKDSK /F from recovery console

Invest in a couple USB drives and install the other os's on them. before you boot up plug in the apropriate drive and boot from it. Thats less complicated and painful to me

please, Let me know :)
