If it is out of warranty, you may want to pop open the plastic clamshell on the processor and clean it out. It could certainly have shorted out if those metal shavings got inside. You should put some sort of cabinet or hang a plastic bag over the system. Leave the bag open at the bottom so air can flow in, but not the metal shavings.

These systems need good air flow, so a cabinet with a small fan and filter would be the preferred method of keeping it clean.

This advice may have come too late for this ACS, though.
