After hard reset - no change same error message and pressing ENTER to continue start up does nothing. Machine still shuts down after 25 seconds.

Tried to boot into BIO, but pressing Escape repeatedly after power has no effect and neither foes f10.

Opened it up and cleaned fan of dust etc and I can hear the fan come on just before the machine shuts off after the 15 seconds.
