Um, they do, providing you aren't running anything Microsoft-based.
I run my system on an old 120MHz Pentium (which is still _way_ over
powered for the task) using Solaris x86, and it has never gone down
except when there's a power cut, which is roughly once every 400
days so far.

Or fail-safe and alert you, which is what mine would do (hasn't
ever done so yet, except when deliberately engineered to do so
to test it works correctly). I also watchdog the system from the
burglar alarm, which will alert me if it fails, and can remotely
reboot it if required (again, never required as yet).
