Monitor flashing ON - OFF

I am writing this in the dark...
when I power-up pc the monitor flashes on-off for approx 30 mins before settling down and staying on.
system is old-ish, but, i think well maintained.
Mesh Tower, AMD Athalon 64 3500+, 2GB RAM, XP sp3, ViewSonic 19" flatscreen, ATI Radeon X800 Pro 256mb graphics card.
I keep drivers updated with Driver Dectective.
Have had some problems with Radeon drivers, but thought this was now sorted.
The Thing is, problem goes away after approx 30 mins, but will return if system is idle for long period - over 1 hour maybe?
Is it a new graphics card or something to do with settings?
Your thoughts and experience gratefully received...

No more likely the monitor itself or power adaptor for the monitor if it has a separate one.
