Application has been blocked from accessing graphics hardware...

[Kraygo]

...crashing.  This started about two weeks a go with a shorter "display driver stopped responding and has recovered."  Now, it simply locks completely and gives the error message "Applicatoin has been blocked from accessing graphics hardware..."  This happens the most when fighting Junghado.

 

I have overclocked, downclocked, updated, and tweaked.....Anyone else have this issue and know of a fix?
