Hey guys, I have a GA-Z77X-UD3H motherboard with BIOS revision 18, running windows 8. Well I've been having some issues with Windows hanging, so I decided to update some drivers, and my bios. So, I upgraded from 18 to 20e. When I did, I was unable to boot, or to see my SSD in the bios. So I downgraded to 19. This time I could see the SSD but was greeted with a never ending blinking cursor at a black screen when I tried to boot. So finally I downgraded back to 18. But the same problem is happening now, blinking cursor at a black screen, and no boot.
