Start up Configutation Script error

@WilliamSmiles  That's exactly it, and the dxdiag shows that one of the graphics drivers is crashing, repeatedly, and the system can't recover it.  So please manually uninstall both drivers and reinstall them.  Here's how:

You can get the newest drivers available from Dell here:

You'll need both the Intel Xe graphics driver and the newer Nvidia driver.  The order of operations here is uninstall the Nvidia driver > uninstall the Intel driver > restart > reinstall the Intel driver > restart > reinstall the Nvidia driver > restart, all while offline.  If this doesn't help, please post a new dxdiag.
