Well well, I'm glad I was able to start a good dialog on this possible problem. I haven't had the chance to get to the log files yet (secular job on Fri/Sat and Sunday morning message make it a little busy), but the chipset is something I had considered but thought, "Nah... too remote." Looks like I was wrong; it might be worth looking into.
Thanks forums. Will do.
I reinstalled Logos and that seems to have solved the problem, but it looks like others on the forums have been having similar crashing issues.
