I think you need to run the full diagnostics routine Dell provides on a disk partition. I think it is the f12 key during boot. Test everything. That should eliminate hardware issues. Do that first.
Next type cmd into the program finder box. Right click on cmd and run as admin. Type SFC /Scannow into the black box and run it. It verifies OS files and fixes stuff if it is corrupt. If that fails to fix stuff. PM me.

Absolutely! Start from the ground up. Don’t waste your time with booting Windows until you know the hardware is solid.
