Hello,
Here a quick trick to force BSOD, it may be useful if the computer is totally unresponsive.
Use those two PowerShell line to edit the registry : (Or do it manually with RegEdit.exe)
#PS2 Keyboard
Set-ItemProperty HKLM:SYSTEMCurrentControlsetservicesi8042prtParameters -name CrashOnCtrlscroll -value 1
#USB Keyboard
Set-ItemProperty HKLM:SystemCurrentControlSetServiceskbdhidParameters -name CrashOnCtrlscroll -value 1
And then, hold down the rightmost CTRL key, and press the SCROLL LOCK key twice, here comes the Blue Screen Of Death..
