Should anybody ever look at this thread, the solution was hardware,
the exact component at fault as yet undetermined, but almost certainly
either a Mobo problem or a failing power supply.

I eventually decided this was an excuse for a hardware upgrade, bought
a new barebones system and took across the drives and graphics card
(the Radeon one) from my old PC. There have been no problems since then.
