My rig is Hp Notebook 15-r106nia Intel core i3 1.7GHz (4GB, 500GB HDD), HD 4400 Graphics, Bios F.39. I updated from windows 8.1 to windows 10 and have done all system updates. I did a system rollover back to 08/08/2015 and after completion and reboot, the screen flicker between the password lock screen and wallpaper screen. The flicker so rapid that I cannot input my password to unlock the lock screen. I've tried F11 press with restart and can not access recovery manager nor boot to setup menu.
On screen error says: LoginUI.exe - Application Error. The instruction at 0x000000006D9BC611 referenced memory at 0x0000008F3CEC7000. The memory could not be read. Click on OK to terminate the program.
What do I need to do please?
