Answer 2

1. To open Task Bar you need to press ctrl+shift+esc and not alt+ctrl+delete

2. Try restarting your computer and then open BIOS (IDK the key to open BIOS in Dell)

If nothing happens, and if your  Drive C is a HDD and not SSD, then the most probably, the HDD have been crashed and all your data is lost...show your pc to a pc store guy...

Btw, how did this happened, did you intentionally ended task of File Explorer or all of a sudden...
