hello EVERYBODY
i would like to explain to you my issue
one of my clients has this problem:
on an Older ASUS Laptop (will be back to let you know the exact model) i try to boot up Windows 10,
Windows logo is displayed correctly,
after boot, screen turns black and it's impossible to do anything
note that the laptop is not turned off. it just displays a "black screen"
i thought it might be a Graphics Card and/or screen issue, so i connected a separate monitor via the HDMI port
Windows was displayed correctly, but only on the EXTERNAL monitor
so i thought it was a Windows/Graphics Card DISPLAY configuration issue
tried every possible combination of settings (duplicate screen, extended screen, etc) without any effect
so thought it might be a driver issue
forgot to mention : AMD drivers
so booted into safe MODE...image was displayed correctly on the laptop screen
so uninstalled all drivers (amd official driver uninstaller tool)
rebooted computer into NORMAL mode and voila image was correctly displayed on laptop
so went to Windows update to download graphics drivers
as soon as the drivers were reinstalled, the screen turned black again so was forced to connect my external screen
so i though the issue came from Windows 10 OS (corrupted drivers, registry, etc)
therefore i installed a brand new copy of Windows 10 on a different SSD
Windows installed correctly, drivers were installed correctly, everything was running smoothly
so i did the same thing for my client's computer
installed all Windows updates so i don't have any surprises
everything was great
all this was two weeks ago
yesterday the client calls me to let me know the issue came back
do you have any suggestions?
will get back to you with the exact laptop specs
thank you
