A little black box appears at the top left of my Windows 7 login screen just before the Welcome screen and the stalls password when I try to enter. HELP PLEASE?

Whenever I turn on my computer for a week, I try and put my password and after the first or the second key it stalls. He again entered my password, but I don't see whether registration in the password box. I also have a little black box that is slightly smaller than the size of a post-it note in the top left area of my screen for half a second, then it disappears and continues to my home screen and office as usual.

I had this problem for about a week, and I can't understand what is the problem. I googled some things, but no one had the right answer. Someone said it was a startup with a defective software program, but I checked and I have the same 4 startup programs I've had there for a year. (DELL Wiireless WLAN Card, IDT PC Audio, Synaptics Pointing Device Driver and NVIDIA Compatible Windows 7 display driver) Everything is up-to-date and I already have Windows Update.

* A video that I captured from my computer of this problem: http://www.YouTube.com/watch?v=GViQv-Xrm0U 

(password stops around 0:42 and black appears at 0:52)

Someone help? I'm paranoid that it might be a Spyware... ? None of my passwords and others are corrupted though, everything has been fine. I am making bluescreens (but not daily). I scanned with Malewarebytes and found nothing and I do that again right now. I also tried Registry Mechanic and Windows Security Essentials, but found nothing.

I have no idea what Forum put it, this is my first time using this site...
