Most likely this is a 3D rendering issue with your gpu. I'd recommend checking your settings first, if you've been customizing them. If not sorry: skip this post. :)
Ensure your Vision Engine Control or Catalyst Control Center graphics (gaming & performance) are all set to Default, and if you are overclocking the gpu card and/or cpu, back them off to default as well (this happens to me if I set my cpu above 4.5GHz, i have no idea why). If you get the crash dump report notification download advisory, don't bother following up on it: it's at least 3 years obsolete (designed for Win XP 64-bit only).
I'd also recommend downloading Open Hardware or Core Temp monitor (free downloads) so you can get a fairly accurate idea of your temps as well. <90degC for (AMD HD/FX) gpu, <60degC for cpu (for AMD83XX series) should keep you safe.
