Dell's Latitude laptop line comes with Windows XP or Vista 7 pre-installed, depending on when you purchased your laptop. All of these Microsoft Windows operating systems have a startup mode named "Safe Mode." When you boot a computer in safe mode, the computer loads only those drivers that the operating system requires. This makes troubleshooting driver conflicts, virus infections and other problems on a computer much easier.
Turn on your computer and start tapping the "F8" key once every few seconds.
Stop pressing the "F8" key once you see the "Advanced Options Menu" appear.
Press the up and down arrow keys to select "Safe Mode" and then press "Enter" to get into safe mode.
