No login screen when I boot, even in safe mode.
One day, I rebooted, and then there was nothing. After Windows finished loading, there was naught but a black screen, and a cursor if I move the mouse quickly. This happens in safe mode as well, and on both my dedicated graphics card (an Asus AMD HD 6450 Silent) and my integrated graphics (which I have no idea about, other than it is a Biostar A780L3G). When I try to refresh directly, with a fresh copy of Windows 8.1 installation media, it says it is invalid, despite it being x64, same as the installed version. When I try directly, it says the HDD is locked, and none of the guides I have followed to unlock it through the disk work. Also, I dont know if this matters or not, but when I try booting into safe mode, at first, when I move the mouse, in the corners, it says Safe Mode. Please respond ASAP.

Your on-board card is this one:
ATI Radeon™ HD3000 Graphics, On Board Graphic Max. Memory Share Up to 512 MB Support ATI Hybrid Crossfire
A780L3G :: Placa-Mãe :: BIOSTAR
I still could not find anything that could explain your problem. Does your MoBo have any kind of HDD protection, similar to HP DriveLock?

Some wired stuff
No, and even if it did, I reset everything to defaults on it, so it would probably be off.
