Well the plot thickens. I chatted with EA. Had me clean out windows temp folders, delete Origin stuff from my users directory and programdata directory. All the time I am like this is not going to work. It didn't. Then he decides to try the game under my sons account at his work. He says it works fine. He tells me to uninstall my 7950 drivers because some of the crashes in the logs from msinfo32 reference the driver dll. Most don't though, they just say the games exe. Then install the newest beta's, which I had already tried. If that didn't work completely uninstall the game and reinstall it. Next create a new admin account and run it from there. I ask him how this will fix it if it runs fine under my account, he says that is how corrupt files work. Sometimes they do and sometimes they don't work. Pretty sure if the file is corrupt it never works. But to humor him, I end the chat and begin the uninstall and reinstall of the newest drivers. No go. Same for the game, stil no go. Create a new admin account, and still no go. By that time it was late so I went to bed. This morning I decide let me try on our 3rd computer which my other son plays on and it works fine. I needed to get to work, so I couldn't test much, but it didn't freeze when I selected the plant. Totally confused now, and I am going to chat with EA again tonight.
Summary. My sons account freezes on computers A and B, but works (more testing needed) on C. A, B, and C play the game fine with other origin accounts.
