The hardware all passes the dell diagnostics and the SMART check on the hard disk.
The laptop is freezing randomly, sometimes at the disk decryption screen, sometimes after 10 minutes of logging in, sometimes at the login screen.

However, However, it seems like if I do the recovery mode, then choose "boot as normal" it works just fine indefinitely.
This is my lsw:
