What sort of LCD monitors and PC's? If they are plain domestic or
commercial types, I'm not surprised - penny pinching in Industrial
environments often works out more expensive than paying for the correct
equipment in the first place :)

I've fitted Industrial panel LCD monitors in a dye works plant where you
can't see 10m for dust and they have survived several years. Likewise
embedded fanless industrial grade PC's without any ill effects. 

The PC's are simply fitted inside large steel IP65 sealed enclosures
with no cooling fans or ports. They are nothing special, just the sort
of enclosure you would fit control or switch gear in. They are about 1m
tall x .75m wide x .4m deep and have two PC's in them. The size is big
enough for them never to get more than a few degrees above ambient. The
PC's are only radiating about 20W and are designed to run at up to 60C
continuous anyway.

What don't last are keyboards - we've done away with them wherever
possible and fitted touch screens. 

Incidentally, clogged up keyboards can cause all sorts of weird
effects..
