Hi there, My mom has a Windows 7 puter (I think it's a Dell). A few months ago while I was down there to help her, as I was typing I accidentally pressed a couple of buttons and it caused the keyboard to stop working properly. I have no idea what I pressed to cause the issue. I tried rebooting the PC, doing a system restore, scanning for errors viruses...all came up clean with no issues. Ever since then, mom's puter now will not let her log in as Administrator. She must automatically switch to another user first. Even then, the keyboard does not work properly. The only solution I came up with is to enable the on-screen keyboard, which (weirdly) then causes her regular keyboard to work properly. Then I turn off the on-screen keyboard. I'll skip the part where my mom has reminded me many times since then that I caused her to have these problems. Any solutions other than replacing the keyboard? I just ordered her a new one, even though she doesn't think that is the problem. We'll see.
