One user locked out over and over again. Not typing in the wrong password.

We have one user who keeps getting locked out of her account when trying to login to her computer.  She can come in at the start of her shift, and she is locked out on her first try.  The IT staff will unlock her, then a few hours later, we get a call from her that she is locked out again.  We have rebuilt her profile on the local machine, still have the problem.  We switched her to another machine, and she is still getting locked out.  Over that last few weeks, we have tried having her call us before she logs in to check if she is locked out before she logs in.  She is locked out and a few times, she isn't locked out, but then a few hours later, she is locked out.  Changed her password, locked out using the new password after one try.  I have also reinstalled Windows 10 and reinstalled all programs and files she needs on the off chance there is a program trying to login for her under an old password.  This also did not fix the problem.  We have checked event viewer and don't see under her username.  We have also tried logging in for her using her credentials while she is standing there, and she will be locked out.  This doesn't happen all of the time, but more likely than not it happens.  Any help would be greatly appreciated.
