Hi, I am Rob and i will do my best to help you.
If you can get into windows at all you can run a system restore which should put it right back to the way it was a few days ago before the problem started. Just make sure that you select the right date. If it wont turn on at all its going to be a lot harder and i probably wont be able to help you till tomorrow. But try just turning it off and unplugging it and waiting a couple of minutes then turning it on again and it might at least boot up to windows.
then do the system restore as below. Make sure to select a date that is before the problems started
System restore instructions - windows 7 8 10
hold the windows logo key and hit R
in the box that appears type
select restore to an earlier date.
Under the "suggested restore" which is usually not old enough to help is a link for "OTHER RESTORE POINTS"
click that if the suggested ones are not BEFORE THE PROBLEM STARTED
choose a date from the calendar that is BEFORE you experienced the problem
hit ok / restore
the computer will start to shut down
a restoring settings box will appear with a status bar
when it finishes your computer will restart with the same settings it had on the date you restored to. your data will not be affected.
It is not perfect. But it fixes a lot of things.
