Windows 10 Lock screen flickering continuously after power on - Inspiron 7348
My laptop bought with Windows 8 home was upgraded to Windows 10 professional in the first year of purchase 2015.
Recently, it was running slow and I tried start up repair. After that restart indicated error with login module. Later at each power on lock screen flickering with loading dots and not allowing the log in.
I called Dell support and they suggested and arranged windows 8/8.1 recovery media.
I wish to come out of this problem by only repair of login module, saving my windows profile and valuable data. Did anybody ever face this problem and what's the remedy ?
