Artifacts when posting (on gamefaqs)

[dlf]

For some strange reason when posting here on gamefaqs I am some of the time getting artifacts on the screen in the posting message box (see picture). It only started today, when typing a message on NGG, I have rebooted that's seem to done nothing. I am folding at the moment. If they appear when I scroll up or down - or shrink the window of the browser and maximize it they go away.

I also some of the time get random artifacts around the browser or screen at random times, again If I shrink and maximize the window of the browser it goes away.

Run furmark for 12 hours and see if you get artifacts there, if you do either increase voltage or decrease the clock on your GPU.
