I have an ASUS 7V333 and have only had the hang problem after many renders or when I use. I have the most certain light sets. When I first used P5 I had problems with a certain background and prop(one of the Transpond ones) but since I started updating my bios I really seem to have solved my problem for the most part. I still turn off P5 after several renders you can tell when it's getting tired, and I save all the time just in case. Marge
