Thank you for the information.
We aren't sure whether the issue was due to AVG update and it seems that this should have happened due to sudden power loss.
Could you check whether you are able to boot your PC into safe mode as mentioned in this article?
Hello Chaz,
We're sorry to know about the situation of your computer.
Are you referring to AVG update or windows update?
Update interrupted by power loss. Now computer will not start past log in. Flashes black screen and flashes tool bar.
No, It was an AVG update. Windows had finished and I was working on the Computer.
AVG said needed to update, do now or later… Clicked to update, lost power, now I can not boot up to main screen.
