Back to stock clock speed core2 E6300, XFX680i LT SLI

[Megagoogleplex]

Hello,

I have managed to OC my Core 2 Duo E6300 from 1.87GHz to 2.7GHz. I have done this by raising the FSB on the MoBo to 1544MHz XFX 680i LT SLI. All is good except the fan noise bothers ears. So I have decided to set the settings back to stock to reduce fan noise. However when I set the bios back to stock the system freezes when it loads the start up items. I have tried resetting the CMOS with no luck, it still locks up. What do I do? PLEASE HELP!!!! Is it possable that Being Over clocked @2.7gig hurt something? Help Please!
