Mac Os X Keychain Hack

How do I change my keychain Password if I don't know what it is?
I got my new MacBook last week, and occasionally I am asked for a keychain password. According to what I've read my keychain password is also my login password, but my login password doesn't work! When I type in what I believe was the password it tells me that it is incorrect.
I may have made the problem worse, because I decided to change my master password with the OSX disc, but that hasn't helped me with the keychain password.
Also, does anyone know why Safari keeps asking me for my keychain password every two minutes. What's wierd is when Safari asks me for the keychain password, a dialogue box appears that lets me cancel the action, after I cancel I can continue surfing with Safari. Very annonying!
Please help this poor cowboy get his wild horse to cooperate.
