I upgraded to windows 10 from windows 8 and not 8.1 with black screen and cursor I had no password so it should automatically load into account but it did not plus I tried ctrl key and enter plus all other key combinations but nothing and waited for half an hour. Please help all suggestions are welcomed!

P.S. I can see the cursor and the loading windows logo so no imbecile answers like graphic card driver or monitor driver for god sake
