I apologize for doing this, but I cant seem to find where to respond to your message....
I do not believe that my card is faulty or overheating or experiencing any technical problems.. it's cooling fan hasn't gone above medium speed while using Blender. It is a little old though :D. Nothing else on my computer seems to have any graphical anomalies.
Anyway, I tested all the Window Draw methods..
Full, Overlap, and Overlap Flip all work perfectly fine.
When Triple Buffer is used, I get the error. Same with Automatic.
