First of all, it's Saturday, so a lot of people that would normally help out (for FREE, I might add), are out/not available to help.
Second, you could have very easily found them yourself. It took me literally 5 seconds to type the name of the motherboard into Google to find this:
http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z77V_LK/#download Just select which OS you have and download whatever you need.
You're welcome.
