My xps 15 9550 keeps restarting itself. It started when I was running a program I used alot before with no problems then it just blackscreened then after a while it loads itself up but not before crashing again a few times either before, during or just after I log onto the device. No program or driver was updated just before the problem and after many attemps it decided to run long enough to allow me to run diagnostics and update anything not fully up to date but I still have the problem.
