Did you uninstall via system control panel or did you use a 3rd party tool that promises to "clean-up everything" and actually breaks your registry?
Did you install DELL' s custom software that interferes in graphics?
Also you have an NVIDIA Optimus rig, which is a troublemaker per se.
Since it works if you pass uninstalling, just don't do it.
1) I`ve uninstalled drivers(Intel Display Driver and NVIDIA driver) from Windows 10 control panel.
2) Then trying to install new drivers, or from the same file, I`ve installed and it worked perfectly.
2.1) I tried to clean with DDU before installing again, same result.
2.2) I tried to reinstall Intel Chipset drivers with -overall command, no result.
I will try to uninstall Alienware OSD and Command Center before installing Intel Drivers now.
If i install new driver over old one my NVIDIA GTX 980M starts to turn on and after 1 second switch off every 20-30 seconds
