Hi @jsgoodrich25  welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support. 

Support for Alienware x17 R1 Setup and Specifications Storage says there are two internal slots, Slot one supports M.2 2230/2280 PCIe Gen4 x4 NVMe cards, and Slot two supports M.2 2230/2280 PCIe Gen3 x4 NVMe cards. The slots accommodate two single drives or a single RAID drive, consisting of two identical PCIe Gen3 x4 NVMe cards. 

Please share the x17 R1 system's storage drive configuration. Thank you. 

Please share what happens after pressing power-on button. Thank you. How to Run the LCD Built-in Self-Test on a Dell Laptop | Dell US 

Hi @jsgoodrich25 thank you for sharing update.

The PC711 is PCIe Gen3 x4 so it does not matter which slot is used. PC/BC711 | SK hynix 

At power-on: Does POST (Power On Self Test) give diagnostic light code. Does Screen work. Does Alienware Splash screen give F2 and F12 options. Does system boot into the Windows 11 operating system. 

There is one drive it is the PC711 NVMe SK Hynix 1TB drive. It is what dell shipped with the tech when they replaced it a month ago.

The system boots and runs fine.  It is just a unknown device in windows device manager.

Webcam works, keyboard works, audio works. I can not for the life of me find what is not working.

Done that and it keeps coming back as unknown. It is really puzzling. 

Install the SD card reader driver.

Hi @jsgoodrich25 thank you for sharing update. 

Please visit Device Manager and delete driver for unknown device. Then Restart (not Shut Down) to save change. When Alienware X17 R1 restarts (with internet), Windows will look online for any driver that is required. If not required, the driver for unknown device will not be installed.
