I install 441.20 WHQL and try 441.12 WHQL. Both results the same.What driver are you installing?
Did you select the exact model of your GPU?
yes, i can. when i go to safe mode and see installed programmes there are no nvidia apps.can you boot into safe mode?
Hemm, i currently work with Ubuntu 19.10 formerly works greatly but now it won't boot just like the Windows did. it froze and won't show the LightDM or even another Display Manager. is it a OS problem? but i'll try your suggestion.When you boot into safe mode, Windows runs on basic drivers, so there would be no nvidia apps. While in safe mode you can uninstall the drivers from the Control Panel; Programs and Features. You should also delete C:\nvidia, or Windows will just reload the drivers that may be casuing your problem. This should allow you to boot into Windows and you can try and install you nvidia drivers again.
You should use the drivers from Asus. https://www.asus.com/us/Laptops/ASUS-TUF-Gaming-FX505/HelpDesk_Download/
