keyboard only works at my sister's house

[BagelAnne]

Out of the clear blue, Windows 7 on my Compaq desktop computer started telling me my password was wrong and would not let me logon.
I carried the fool thing to my sister's house to work on it together as she has a rescue disk for win 7

We followed the directions on How To Reset a Windows 7 Password [Easy, 15-20 Min] and were able to create a new password that worked.

We did a cleanup using ccleaner, atf, Jrt awd and windows own disk cleanup. Everything was good
We scanned with Malwarebytes, Spybot, Eset, MSERT. Found lots of minor stuff (Mindspark, Open Candy, Yontoo, Couponbar, etc) but Spybot also found and cleaned W3i.105.fraud and Malwarebytes found w3i.A. Not sure if these are awful or not.

Working great, so I lugged it home. Connected all the cables and the password once again would not be accepted.
Brought it back to my sister's and no problem with the login password.

What the heck could the issue be????
Any ideas what to check next?

I see you have post on Bleeping Computer asking for help with the same problem at Posted Yesterday, 08:04 PM

My login password only works at my sister's house - General Security

I personally would not use two forums to fix one computer.
One hand doesn't know what the other hand is doing sort of thing.

In my opinion Bleeping Computer is very good at infection problems and has been for years.

Despiration has caused me to shout from the mountaintops.
You make a valid point, though, and so I usually will work with the first responder and report this to later responders.

My sister's keyboard works at my house

I have removed her password via User account
Going tomorrow to see if the keyboard has any other issues

Removing the password worked. Neither of us is brave enough to create a password and possibly mess things up again.
Thanks for your help.
I think we are all set now.
