So I'm not really sure what has happened but I was trying to reinstall AMD Catalyst or another driver system/manager. It requested to restart the computer but now it loads to the login screen and I can't use my mouse and/or keyboard. Not really sure what I have done or how to correct it.
The back lighting lights up on the hardware but nothing happens when I try to use them. I have moved to other usb slots but nothing.
I have a Sapphire ATI HD 7970, AMD FX-9590, Gigabyte GA-990FXA-D3.
I know this information probably doesn't help much but I have no idea what I have done.
