So rececently i got the xps from my girlfriend cuz she didnt used it anymore. She havent used it for like a year anymore. As i got it it showed lot of critical updates for system and drivers. After I installed them the touchscreen and the pen functions didnt work anymore. So I tried to restart the system. Thats when stuff got crazy. The system wouldnt boot, it got stuck on loading screen. So I had to reinstall the system. Thats when it got even crazier. When I wanted to pick a particion where windows should have benn installed no drives showed up. Then i researched for a long time and found that i have to manually add the drivers to be able to install windows while in RAID mode. So i flashed the usb drive with the IRST-Drivers.

Then I was actually able to pick a particion to install the windows. I installed windows. I downloaded the Dell Updater software. "Dell/Alienware Update Windows Universal". It wanted to install me like 6 drivers. After it tried to install them 4 of were stated as Failed to install. After that the updater said to restart the system. Then while it said Restarting System for like 10 minutes a BlueScreenofDeath popped with the error message DRIVER_POWER_STATE_FAILURE. After that it got stuck on the booting screen again just like before and had to reinstall win again just like before. I did that like 15 times already. I have tried everything I tried to update with the windows build-in updater I tried to manually download and install the drivers. I dont know what to do anymore. Anyone some ideas? 

Update:

I can provide pictures if that helps
