Windows 7: Dell Inspiron 14z Auto Logs In and starts Device Diagnostic Tool

Dell Inspiron 14z Auto Logs In and starts Device Diagnostic Tool

Hi,

I have a Dell Inspiron 14z that I recently received from a friend. When I boot it up, it automatically logs in to an account with the name "TMO" and starts up a T Mobile Device Diagnostic Tool. I cannot get out of this. When I try to minimize it, it bounces right back. When I try to press the x button, it gives me three options: Restart System, Restart Application, and Cancel. Restart System just restarts and brings me back to this screen. Restart Application just brings me back to this screen, and Cancel just does nothing. When I press Ctrl-Alt-Del, it only gives me one option: Switch User. I cannot add user, and the only option is to click TMO, at which point it signs in again. Clicking on the Ease of Access center doesn't work. Shutting down doesn't help either because it boots into the Device Diagnostic Tool each time. I've tried going into Advanced Boot Options, but it seems like the key combinations are different from what I remember. On startup, pressing these keys do the following:

F2: Aptio Setup Utility
F8: Nothing
Shift-F8: UEFI Options which takes me to Dell Diagnostic Tests (not Device Diagnostic Tool)
F11: Automatic Repair which just says it will repair and then continues to sign in and start the Device Diagnostic Tool
F12: UEFI Options which gives me a choice between Windows Boot Manager and UEFI Network Card.

Do I need to boot from a USB drive and reinstall windows? Thanks
