The monitor?

Thanks for the reply.

Sorry, I knew I'd forget to post something vital!

I've tried other monitors and cables.

Were they all CRTs? DVI or VGA?

CRTs are quite vulnerable to low-frequency EMF interference. Anything
from nearby fluorescents to overhead power lines. Analogue signals are
also vulnerable to interference.

It's not the CPU.

This machine is normally connected to a CRT via VGA. It is currently in
another room, (my workshop) and connected to an LCD via VGA. I will try
the LCD via DVI in the morning.

Apologies for own-post reply!

Using DVI made no difference.
