Dell laptop rejecting my password

I turned my computer on this morning (XPS M1330), it started updating automatically with updates and then would not accept my password. It gives the error message, " the user profile service failed the login." I do not have any software so I can reset the password, as I bought the computer from my brother about 2 years ago. What can I do? It doesn't seem right that the computer did these updates and is now rejecting my password with no solutions on how to change it beyond having the software.any help would be appreciated - thank you!

If the user profile fails to load, the SAM won't load the password.  When this happens, there's a very good chance a failing hard drive is at fault.

Power the system up, press F12 a couple of times and boot to the Dell diagnostics.  Run the tests, and then boot to the full 32-bit diagnostics and run an extended hard drive test - you will likely find the drive has developed bad sectors where the user profile is stored, in which case you'll need a new, 2.5" 7 or 9.5 mm SATA notebook hard drive.

Thanks so much for your response. I tried pressing F12 multiple times but the computer doesn't seem to be recognizing it from the first login screen where they ask me to enter my password. I also tried pressing F12 when the computer was booting up, before it got to the login screen, but that didn't seem to make a difference. Any tips on how to get past this? Thanks again!

Start pressing F12 immediately after you press the power on button.  On some systems, FN-F12 is required.

Thank you - tried that twice (once with FN F12 and once just F12) immediately after powering on and it doesn't seem to recognize it before getting to the login/password page. Anything else I can try? Thank you!

Try holding down the D key through the POST process.

Just to clarify, I turn on my computer and then immediately hold down the D key until it reacts and not do anything now with the F12 or FN keys? I'm not too computer/tech savvy so just want to make sure i am understanding. Thanks!

Holding down D should trip you into the diagnostics the same way F12 should.
