I formated my drive and preformed a fresh install of Windows on my sager np8158 and no graphic drivers want to work

I got my sager np8157 a month ago or so and after having overheating problems that i fixed i wanted to preform a fresh install of Windows the graphics driver for my nvidia gtx 1070 were 411 i dont know the exact driver version, anyway when i first got the laptop and updated the driver it did not detect my laptop screen and would only work on a secondary monitor now after the fresh install i thought it would work now it still has the same problem and i cant find the driver i was on (i tried many drivers and all give the same outcome) laptop screen goes blank and turns off then it doesn't show anything (works with a external monitor) and if i shut it down and back up it shows the sager then loading then the screen shuts off

lets recap: gpu drivers install fine (no error messages), but once installed the internal screen goes blank? but external display still provides an output?

have u cleaned up with DDU before installing a different driver? does the internal screen work normally before gpu drivers are installed? what happens if u reboot into safe mode with a gpu driver installed?
