Thanks for your help Jeff! I had never opened up the computer before to see what was inside (It belongs to my boss). Sure enough, there was only a CPU fan and no case fan. I think it was what was causing the blue screens. As for the crashes, I found the answer for that as well! I talked on the phone with Adobe, and they suggested I update the graphics, audio, and cpu drivers. None of this worked. He also suggest that I download a program called memtest and test the RAM for errors. Sure enough, there was a memory error. We replaced the memory and now it works!
