BIOS update on MSI z77a gd65

After updating the BIOS to the latest version, Windows (7) does not start, you have to roll back.
I decided to update to the latest one due to the fact that, with OC Genie turned on, it accelerates my 3570k to 4.2 gh, but for some reason the games freeze, they say you need to update the BIOS and everything goes away
Who knows, tell me
