So, I was trying to unlock the cores on my CPU, its a MSI 790FX-G70, when i finished the ACC/Unlock cores stuff i saved and exited bios. That was my mistake. Once it rebooted, i turned it on. and no display. Meaning my entire screen was black. I'm not sure how to narrow it down, and if it helps my Graphics card is a Diamond 5850. I mean, all my drivers were updated. So I don't know whats wrong. The Bios is MSI's newest for my mobo 1.7, I'm running Windows 7 Home premium 64 bit. PLEASE HELP!
