I have this problem not only in this version but also previous versions of GPU-Z.
GPU-Z some times loads and some times not, it remains in memory when it does not load. Its some times shows an error about driver or something. and When it doesn't loads some programs stop working like ATITool , ProcessExplorer etc...
It also happened in my previous mobo Intel D101GGC with and without Graphic Card, and still having problem with my new mobo Asus P5K-V with and without Graphic Card.
My Graphic Card is ATI X1300
