Kingdom Hearts Birth by Sleep Final Mix - ULJM05775

[wcamicase]

Hey guys, I'm having some problems, my graphics card crashes a lot when I'm playing this game
After a bit of playing the game freezes (the music continues) and after a bit the screen goes black, and return to normal, the game won't respond further than that and I get a message saying my AMD graphics card crashed but has successfully recovered, thing is that I need to return from the last save point and that's pretty annoying..

I'm using rev2614 and when I try a newer revision the game simply freezes in the first thing it appears on screen..

I have my latest log, dunno if it might help
My specs are on my signature
