RE: Inspiron 3847 BIOS crashed? USB keyboard is not working

Have you tried a different USB keyboard?  Or tested this one on a different PC?

You can try clearing BIOS, when you have a known working keyboard:

Power off and unplug PC. Press/hold Power button for ~15 sec. Open case and remove motherboard battery. Press/hold power button for ~30 sec. Reinstall the battery. (Is it time for a fresh one?) Close up and connect only mouse, monitor and keyboard. See if it works now.

Check the manual for details about removing/reinstalling the battery: downloads.dell.com/.../inspiron-3847-desktop_owner's manual_en-us.pdf
