my discrete graphic card just burnt out, I switch to on-board graphic card
startup already looks fine, but after the windows startup logo shown, the login screen didn't show up.
just a black screen
I can hear the normal window startup sound
I tried boot to safe boot, everything is ok here. I tried enable the "Base Video" option through msconfig
but still same problem.
I already uninstalled the display driver (GeForce) at safe boot.
I guess it's something to do with display setting/detection.
*1 update
I tried a clean boot, still same issue.
I chk the reg:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell value is explorer.exe
*2 update
I tried the vga mode at the bootup screen option, still same problem.
