You can try to Restore BIOS settings to defaults and check if it helps. If you don’t know how to restore default settings then, I would suggest you to get in touch with the system manufacturer for help.

Warning:
Be careful when changing BIOS settings. The BIOS interface is designed for advanced users, and it's possible to change a setting that could prevent your computer from starting correctly.
Updating BIOS should only be done if necessary (to solve a compatibility problem, for example). It can be a complicated process, and if an error occurs, your computer could be rendered inoperable. Be sure to follow the manufacturer's instructions exactly.

I’m confident that steps suggested above will help us fix your issue. If you face any further issues, please reply to this post and we'll be happy to assist you further.
