I am using a gigabyte GA-Z77X-D3H I managed to install windows from a USB and then continued with all the driver updates. I wanted to overclock my i7-3770k so I restarted and pecked the delete key, the splash screen came up, and then it proceeded to post but just remained black, nothing happened, I waited for 10 minutes and nothing came up. Windows appears to be fully functional and I am using a ps2 connector for my keyboard. Any suggestions? Thanks!
