Latitude 7559 no boot
I have had this machine for a couple months. Last week it started bugchecking with DPC watchdog fimeout and driver power state failure bugchecks. This happened one minute after any boot. The system was unusable so I ran the windows recovery including deleting all files and application. This recovery also failed (dialog stating installation had failed, no reason was specified). I subsequently created new install media using the Microsoft media creation tool. This installation succeeded, then required a reboot due to an (auitomatic) driver installation. This resulted in the machine booting into a black screen.
It is a 7559 with a single 8gb module, 1tb SSHD, 4k screen, NVidia GPU, FW 1.2.1, intel 1x1 wifi/bt (all stock)
Any ideas on how to unbrick the machine?

Have you run a complete hardware diagnostic on the system (including an extended hard drive test? F12 at powerup - that would be the first thing to do if you haven't already done so.
If you have, and nothing has shown up, stop the install before the automatic driver install and manually install first the Intel and then the nVidia video drivers. Use the ones from the Dell site - not from Intel and nVidia.

I did run the HW diag yes ... said it was fine.
I ended up reinstalling again and turning off Windows update. Installing drivers one by one, it turned out it's the NVidia driers that brick the machine. Even the ones from the Dell web site. I suspect the same drivers are getting installed via WU

Both version of the NVidia drivers I tried brick the machine (A03 and A04). Sent in for repairs.
