On another PC, download the
Windows 10 media creation tool and use it to make a win 10 installer on USB
try start up repair:
change boot order so USB is first, hdd second
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose start up repair - this will scan PC and maybe fix this - will ask for logon info
try safe mode
boot from installer, on 2nd screen after languages, choose repair this pc, not install
choose troubleshoot
choose advanced
choose start up options << this menu may not be there which is a pain.
hit the restart button
choose a safe mode (it doesn't matter which) by using number associated with it.
PC will restart and load safe mode
Safe mode just tells us if its a driver problem or not.
Use this and see if PC hardware is working right, will tell you if its windows at fault or hardware - can also use to copy files off laptop: http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/
