A flaky power supply could be the cause. 3. Memory problem. Run memtest for several hours. You also don't mention if you have the system powered off for a considerable length of time. That would even more point to heat or weakened components. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
