Rick, thanks to you and Cam for pointing me to the Kernel Common Problems link. I'll start working my way through that. I have been looking in the messages log and have not found anything that looked informative. So far, the computer has frozen or crashed in every situation you listed, during boot up, after a few minutes, and after a few hours. It seemed to freeze while running yum, but it froze when not running  yum as well. In other words, I haven't been able to detect a pattern so far.  I'm willing to replace the motherboard, but I want to know that's the source of the problem before I do. I've suspected other pieces of hardware along the way, but replacing them has not changed anything yet.This has been aggravating.
