I flashed this BIOS on my Y580... It seemed to work just fine, and I left my BIOS settings at default after flashing. However, after I shut the computer down and then left it alone for a day or two, now I can't boot it up anymore. I can't even get to a BIOS screen. The power turns on, but I get no beep (if I hold down a button for long enough it will beep at me, and the system is otherwise totally unresponsive). Is there anything I can do? I didn't change the settings at all, I just flashed the BIOS and left the settings at default.
