Hey all. following a system restore, i now keep getting an error message when I switch the pc on. it pauses and prints the following on screen below the hd master/slave etc... info.(this is before it even gets to windows "Warning! cpu has been changed, or cpu ratio changed fail. please re-enter cpu settings in the cmos setup and remember to save before quitting." then I can either press del to enter BIOS or F1 to continue (which starts up the pc with no further problems) anyone got any ideas?
