At that black screen try safe mode
(use the cursor and press RETURN). Normally you tap F8 a couple of times before the windows welcome screen to get that menu.
While loading your drivers just before getting into safe mode press ESC if you get stuck.
In safe mode, run some anti-virus etc.
Then open your Windows Explorer and right-click your C drive. Choose Properties
. Where it says Error checking
press the box Check now
. It says it will do the check upon a reboot, so reboot now.
Best report back from there before attempting anything else.
