Hi

I have a windows XP home. I have a problem that started after the power went out one day. Came home and seeing that my time and date set for the year 9999, and then I insert a flash drive from my office computer. Attempt to reboot the in safe mood, that did not work an error appears that that the computer had been shut off wrong. Other symptoms are as follows: Task Manager unable to be accessed can’t run CCcleaner, Ad-Aware, or Avira Anti-Virus.

How to sort out this mess please help me? I am there in big trouble, please help me?
