Could Not Log on with Primary User Account
I own a Sony VAIO VGN FW317J with Windows Vista Home Premium. Yesterday night, I wanted to turn on the light function but pressed F7 by mistake. After that, two choices came up: the first one was about LCD display and the second (which I selected) was something I forgot. Since then, I cannot log-on to my primary user account despite being able to log-on with my secondary user account. Can anyone help me with this? I really need to solve this problem as soon as possible.
