What card is it and how old? What temperature is it reaching at load? Is it/has it been overclocked? Do the dots appear as soon as you change the settings or after a while?
Depending on the above it sounds like an issue with the card's memory. It may or may not be permanent if that is the case. If its an old card then a baking it may help, solved a similar problem with my old 9800 gtx this way. If it is newer I would have some reservations about baking it incase I ruined it.

Hmm it sounds like it could be the same issue my 9800 gtx ran into. It is a hardware fault for sure so I would say go ahead and try baking it if you want to try and get it going again.
It will melt the solder and allow it to reflow to the components, it solved my problem. The only issue is that some people might not want to put their graphics card in the oven and it could potentially damage it. By the sounds of it though you dont have much to loose by having a go. If you do go for it just make sure you take the heatsink off the card and clean away the TIM before you start. If it works it is hard to say how long it will work for...I baked my old card 3 times, each extending its life by ~ 3 months.
I'm tossing my dead gtx465 in the oven when I get home! ....well it's not totally dead, but it won't output video on it's own, only shows up with 224 cudas, and I have to reboot like 8x to get it to be detected. In the oven she goes!!! Hahaha
