White dots will appear on the dark areas of one of my monitors. I can temporarily fix this by unplugging the the monitor from the gpu and plugging it back in. It's occurred on both monitors before.

When I move a window around that contains the dots, they stay in place relative to the window. As I move a window towards the edge of the monior, any dots that get within perhaps 1 inch of the top/bottom or 2 inches from the left/right will fade, then return to normal as I pull the window back.

The only way I can think that I may have damaged the gpu is through overheating - sometimes when I play an intensive game it gets quite hot. I always make sure to keep HWMonitor open when playing these games, however, and it never goes above 73-74C, but usually hovers around 70-71C. From what I've read those aren't dangerous temperatures, especially since they are only at that for a few hours at a time.
