Ok what you want to do is go into your PC's Bio's settings at startup.This is usually done by tapping the F1 or F10 key while the system is booting up. (note the key may vary from system to system check here for the varients

Once in your Bio's you want to look for your BUS speed options.The standards settings are usually 66MHZ,100MHZ,133MHZ,and i believe ive seen 166MHZ before as well.simply check to see what it is if it is set to 100MHZ bump it up to 133MHZ save your settings and reboot.If everything starts up fine then you are good however if everything does not you will have to go back into Bio's and change the settings back to normal.
