It will look like a DOS box, aka, black screen with large letters. There will be 3-4 options, you want "Safe Mode." Don't worry about networking or anything, and make sure it's not just with the command prompt option.
If that doesn't work, a more generic solution:
Start Menu-->Run-->type in msconfig and hit enter-->Click on the BOOT.INI tab and check the box next to "/SAFEBOOT" under the Boot Options section-->Reboot and you will be in Safe Mode. After you are done tinkering around in Safe Mode and you are ready to reboot back to normal boot, you have to do that again while in Safe Mode and un-check the "/SAFEBOOT" option then reboot again.
Good by nature, but evil by my own free will.
