Reporting Dell Inspiron 5570 BIOS issue

Greetings, I see that there's no place to report an issue so I'm doing it here.

We received a Dell BIOS update for the Inspiron 5570 in July, the problem is that it has an issue, fullscreen applications like games crash constantly after that BIOS update. The only solution is to downgrade the BIOS to a previous version, after doing that, the applications don't crash anymore. What I'm requesting here is to take a look and fix that BIOS file so that we can have the latest version without issues and problems.
