What I see here is you are playing NBA 08 live game on a PC. After playing for a while it crashs to desktop, and it only does it in this game only am I right? Now what kind of graphic card to you have?
Don't say mobility. What I want to see is radeon HD 6570 or what number you have. This way I will know what you are using unless you are using the integrated graphics that came with your PC.
This is what I would do. First open up your case and clean out all the dust build up using compressed air. After doing that try playing. If the problem is still there. Then we go to the next step.
We will need to see what your temps are on the graphic (GPU) You will have to down load MSI Afterburner, that way we can see how hot your GPU gets. So lets start there. Here is the link to MSI afterburner.
Also on that page look for the manual on how to use it. It really isn't that hard to ues.http://event.msi.com/vga/afterburner/download.htm
