The green dots you are seeing usually indicate a Graphic memory problem.
This was always a common problem with some of the old VOODOO cards,the same
technology NVIDIA bought and uses.Either that or you have overclocked your
ram to the max. Another thing you can try is getting RAM heatsinks for the
card.

Well it definitely wasn't overclocked and i even tried underclocking it
to no avail.

I've sent it back to where it came from and now have to wait 7-10 working
days while ebuyer.com check it out and hopefully send a replacement.

Thanks
