I am having a similar problem.  I was recently given (by my inlaws) a Dell Inspirion 910 for my children to use for school.  I cannot get the darn thing up and running!  When I turn on the computer it gives me 2 Windows XP boot choices.  They look identical, though if I choose the top one the computer boots up, but if I choose the 2nd one I get an error message.  I can't figure out how to remove this broken version of the operating system. Then when I get the thing on and to the main screen I get a popup for Microsoft Security Essentials talking about the end-of-support for my operating system.  After this the computer seems to freeze up most of the time.  When it does continue to work it takes a few minutes to process each command.  I just want to restore the whole computer to factory settings and start fresh, but I dont know how.  I tried to run WINNT32.exe but the computer said it could not find it.  Help?!?
I have recently bought a Dell Inspiron mini 910 but it didn't have a system disc. I would like to restore the laptop to it's factory settings. Can you help point me in the right direction please.
