Windows 10: Starting up windows all I see is black and my mouse cursor

I need help with a problem, every time I open up my computer Its a blackscreen with only my mouse cursor on it. I tried going into advanced troubleshooting options and my password was incorrect even tho i reset it and typed it in 3-4 times very carefully. I tried resetting many times but it cancels out and there was a problem with it apparently.

Black screen after 'Starting Windows' sequence

Hi,

I locked my computer before I went away for a couple of days and came back to a black screen with only the mouse cursor visible.
Every time I try to start the computer, it will go through the initial startup sequence of displaying the manufacture's logo for the motherboard and then it will say 'Starting Windows' After which point it will just display a black screen with only the mouse cursor visible.

I can access the motherboard's features absolutely fine and the options such as safe mode, start windows normally etc are available.

I've tried:
Startup Repair - No problems.
Windows Recovery Diagnostic Tool - No problems.
Chkdsk - No problems found.
There are no dates available for System Restore.
It won't start in safe mode. It runs through the loading then same result as before, only the cursor visible.

As a last attempt I cleared the CMOS, but with the same outcome as before.

I thought it could perhaps be GPU related, but it doesn't seem so.
I have 2 GPUs, both R9 290. They were both working absolutely fine before I left - no problems whatsoever.
I have tried them each one by one but they produce the same result individually ( after 'starting windows' a black screen with only the mouse cursor appears).

Specs can be found in my 'system specs' section.

Any suggestions?
Thanks.
