Ok, what I am going to do is show you how to bypass or (hack) a password protected windows xp computer. first, restart your computer>press F8 before it boots up, a menu will come up>select safe mode>restart in safe mode>the admin account comes up> click on it and click yes when the small menu comes up> the computer should boot to the desktop now>select start>control panel>select user accounts>select change account and follow the prompts to creating a new account (make sure that the administrator radio button is selected) put in your new password, etc> restart your computer. You should now have administrator privileges on that system. Let me know if you have any further problems. :-)

I don't know what TRIPS out sounds like, but there are number of different things that could make sounds when powered up. Let me know what and where the sounds are coming from. I am including a link for delll support for your system. Let me know if I can be of any more help. Larry
