in my comp so i can upload it?

if you are doing this for diablo 2, it will go into your diablo 2 folder.
for anything else, it's just like you copied text on the page. if you open up paint and hit ctrl+v (or paste) your screenshot will show up there.

Right after i hit print screen my power went off due to bad weather and my comp turned off. Where does it go in my comp...plz help me

Typically when you press "PrintScr" on your keyboard it will goto your clipboard. Simply open Paint and do: CTRL + V. It will paste the screen capture into the paint document.

i tried but when the power when off. it cleared my clip board thats why im trying to retrieve it from somewhere in the comp

like i said, if it was diablo 2, it will be saved in your diablo 2 folder.
otherwise, when your computer shuts off you lose whatever you had saved anything that was temporarily copied (i.e. whatever was captured when you pressed print screen).
can't recover it.

Clipboard information is stored in your RAM. Data on your RAM is only temporarily stored, when you turn off your computer it will clear your RAM and such information will be lost. If you used the print screen button in a game like World of Warcraft or Minecraft, it will have been saved on the HDD in a specific folder.

I was playing pokerstars when it happened...where would it be in the pokertsars folder?

I'm sorry I'm not familiar with the Poker applications.
