My Wife's Sony Vaio notebook running Win 8.1,
now hangs at the login screen.
Screen slow to appear from boot,
finally paints the login screen correctly, with her personalized photo, her name, and a rotating cursor.
but IO is not functional, mouse pad won't make the cursor move around the screen
rotating "circle" will rotate about 10 seconds,
then quickly flash the input bar and we think it says "password hints", but disappears after 1/2 second,
back to rotating cursor circle. This repeats over and over.
Can only hard shut down.
This is first time it has ever done this.
Last night, she was complaining of slow internet, but the rest of our laptops were normal speed.
You guys have saved me on other computers, including my own.
Thanks in advance
