Hi High Tech Key,
If you are switching your spindle on / off with a relay which does not have adequate arc suppression (across the contacts) then the noise spike generated may well crash your computer.
SSR's such as this one, switch at the 'mains zero crossing point' and produce much less noise. They can be driven from your existing relay and just require a small power source.
