I used to be able to go to: start/turn off computer then next window I had 3 choices to
1: hibernate computer
2: Turn off computer
3: restart computer
Then I reinstall window XP and the choice to hibernate computer is gone how do I get back the hibernate option thank you

I don't think you want plumbers to advise you on "how to hibernate computer". :D Repost your question in appropriate forum.

Open Control Panel,open Power Options,select Hibernate Tab,check Enable Hibernate Support, Good Luck.
