Upgrading

Hi all,
Appologies first, if this is old hat to you 'wizards'.
I am upgrading my m/board, and graphics card and CPU. Now, after I install the board, card etc, can I just put the hard drive back in, and will it boot up ??? Obviously Windows is installed on this disk. I know I will have to point the bios to boot from IDE, at least I think thats what I do :) The only disk I can find that originally came with the computer ia a recovery disk, whatever that does ? Never used it !!!!
Secondly, my new card is an 512mb DDR2 XFX6200. Browsing thru my M/board manual, I notice it says only install a card of +1.5v. What does this mean, and how can I find the card spec....looked everywhere and drawn a blank >:(
ANY help appreciated, sorry again if this is 'kids stuff' to you
Regards,
Tony C
