Just because when u raise the FSB while oc'ing u are also making the ram work harder. And doing one of the above things will reduce the load that the ram has.
But since u only oc'd 200mhz I doubt it's the ram, but still worth checking out.
Since he said he didn't know what he was doing I don't think it wise for him to fiddle about with it anymore.
Go into the BIOS on startup (there should be an on-screen prompt to tell you which key to press, may say 'setup' instead of BIOS) and find the menu with all the clock settings information (on mine it's called 'advanced BIOS settings') and you should be able to reset the clock speeds with a press of a button. Simply save it and exit.
EDIT: This is for WOOT, sorry about that mammikoura
