I got 2 PC's here, that my mother asked to fix, but I can't log in. Admin accounts have a password set. I can't boot from USB, they're to old and don't support it. The DVD drive doesn't seem to be working either, though I can't tell if it's broken or just not allowing me to boot.

Is there any way to get in windows XP SP2, without a password, USB or DVD?

The computer is a Dell latitude C840.

You could remove the hard disks and attach them to a computer that will boot from USB or DVD. Then use standard techniques. Finally replace disks in original computer.

Ah yes, I'll see how that works with laptops – Simon Verbeke May 15 '12 at 19:05
Can't get the latest screw unscrewed, almost seems like it's sealed with glue – Simon Verbeke May 15 '12 at 19:31
Might be easier to install a working cd/dvd rom. – Moab May 15 '12 at 20:43

If it is XP Home edition, boot into safe mode, this is the hidden administrator account, hopefully no one ever password protected it, it is not by default. Once in safe mode you can use control panel to clear passwords.

If it asks for a password, leave it blank and hit enter, if this does not work you will have to try the suggestion by RedGrittyBrick.

"Admin accounts have a password set.", so that won't work – Simon Verbeke May 15 '12 at 19:20
@SimonVerbeke Is the Administrator (the built in) account password protected? – Canadian Luke May 15 '12 at 19:37
@Luke Yes, that one as well – Simon Verbeke May 15 '12 at 19:38
