The entire system was built by me, all components brand new last September, so everything is less than 6 months old.
Now, let me give you an update.
I've swapped the video cable over for one which is known to work and I still get the same problem, which kind of points to the graphics card.
However, last night, when trying to boot the system, I had a post error indicating that no keyboard was present.
The keyboard & mouse were bought the same time as the rest of it. It's a Logitech wireless model, so the first thing I did was to install new batteries in both KB & mouse and rebooted. Same thing, keyboard not present. I hooked up an old wired keyboard/mouse and this worked straight away.
The wireless keyboard works perfectly in my other computer.
So..... apart from the obvious "what the [bleep] is going on here", is this pointing towards a motherboard problem?
I did try several different USB ports for the Logitech, but it steadfastly refused to recognise that a keyboard was in fact plugged in.
All USB ports work as expected when inserting memory sticks etc.
Thanks in advance for any light you can shed on what is becoming an extremely frustrating problem.
Oh yes, the core system, (Motherboard, RAM & CPU) were bought as a bundle, built & tested to eliminate compatibility problems.
