Cant log-in in my User Account !!!

Hello people !!!
Not sure to start this thread,, but it seems more like a networking problem or maybe not.
Today morning , i was able to log-in in my User Account,, but later on at night,, i wasnt able to do so. Can log-in into other user account on the same machine,, but just not mine.
When i type in the password, a message appears,, stating that theres some damage to the device,,, and the 2nd meesage comes ...saying that its gonna log me in ,, in another temporary account,,,, but the info and settings wont be saved once i log off.

Its really frustrating,, cos i have all my pics and documents in my account....and i dont really wanna create a new account again,, and bring back the settings i had.

Does anyone knows whats going on ,?? Is there any way to fix this ?? Kindly help !!!
