The problem, as it turned out, was that I needed to update the BIOS of the mobo to support the AMD 1090T, and it has been rock-solid ever since then. My mobo was an earlier-rev 880GM series. So you might want to check to see that your BIOS is compatible with the 1090T CPU. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
