Yup updating the drivers could probably fix the problem, usually the best source for drivers is getting them from the manufactures website since using windows update isnt the best choice. Are you sure that you did a stress test and checked the cpu clock speed...... however i think this could still be a software problem.....
tiny fx wrotedid you solve the issue?
I think so! it hasn't froze since the bios update (2 days ago)

thanks for asking!
