Hope it's not the video card as it's only been in use for a little over a year!!  :(

But on a positive note I changed render threads to just use 1 core in both PP2010 and Max and it seems to have done the trick as markschum suggested!!  I'll try it in Lux after the Max render is done!  

Mind you both renders did seem to take longer but I can live with that!!

You are pure, you are snow
We are the useless sluts that they mould
Rock n roll is our epiphany
Culture, alienation, boredom and despair
