My late 2009 MacBook has been crashing

Hi, recently my MacBook has been crashing and I reformatted the computer. It worked fine for a little while and then began crashing again, especially when using more intensive programs (Adobe products and games). Here was a copy of the report from the last crash, I was hoping someone here might have some insight into what might be wrong with the computer based on this.

Thank you for your help!
