I ran the BIOS update for XPS 8930.  The restart did not work, it does not boot up. I've read other posts, and followed the directions for clearing the CMOS settings.  The computer does not even get the splash screen.  It cycles between on and off but nothing ever shows on the screen and it does not respond to any keyboard input. I can't believe this has left my expensive computer worthless.
