Need reinstalling Sony Vaio VPCC B4Q1E - lack drivers!
Lost my father. Have his Sony Vaio now.
Helped him before to upgrade to Win10. 
Changed password. Stupidly, I forgot it.
No support from Microsoft.
Lack drivers to reinstall Win10. Seems to be very special ones!
No support any longer on your site. No one to call.
- Please HELP!
