Aurora-R4 Operating System freezing at starting Windows

Problem: Alienware Aurora R4 blank screen or system hang during Windows boot.

Description: Some Alienware Aurora R4 systems may display a black screen and/or hang while Windows is loading. 

Solution: Engineering is aware of the problem and working towards a solution. To work around the issue, follow the instructions below -
* Restart the PC
* Press F2 to enter the BIOS setup and record the current Boot Mode value (either Legacy or uEFI)
* Press F9 to load the Optimized Defaults
* Choose Yes at the pop-up prompt.  This disables the CPU overclocking and resets the Boot Mode
* Press F10 to Save and Exit the BIOS setup
* Choose Yes at the pop-up prompt
* Immediately upon the subsequent reboot, press F2 to enter the BIOS setup and manually restore the prior Boot Mode value from the first step
(either Legacy or uEFI) 
* Press F10 to Save and Exit the BIOS setup
* Choose chose Yes at the pop-up prompt and allow the PC to normally boot to Windows
NOTE - Restoring the CPU overclocking will create the system hang so leave it off until we come out with a permanent fix.
