hi i have another itunes account on an old pc how do i recover the account

Recover it how ? If you've forgotten the password for it then try http://iforgot.apple.com to get it reset.

If you want to copy its content from that computer to a different computer then there are some methods listed on this page which let you copy it : http://support.apple.com/kb/HT4527

Or do you mean something else ?
