since installing a Powercolor 6950 I have noticed that occasionally whilst gaming pink splodges appear now and again. They look like paint splats about 2-3cm big. Does anyone know what this is caused by and how to solve it? Its not a huge problem as they only appear for 1 frame every so often but its a bit annoying.
Another thing to check (as stupid as it sounds) is the cable. Sometimes a bad cable/connection can do this as well. Re-seat, or replace the DVI/VGA/HDMI/ect cable and see if this helps. If not, RMA the card (or turn down your OC) as mentioned above.
