I have the flashing screen that I can't do anything with, so i followed the instructions on how uninstall windows 10, which were great easy to read, but never got to question 6. Choose an account - I only got error message WDF_VIOLATION.. Than rebooted and back to the start which I tried about 10 more times with the same error message. Does this mean my 12mth old computer is dead?? I'm not a computer wizard just a boring email/googling & office Mum. Thanks
