Have you checked with memtest86 to see if that > reports anything? Thanks for the suggestion - I assumed the memory was OK since I have never had problems with Windows XP or i386 Fedora.

Unfortunately I'm not sure how to measure the CPU temperature. I'm compiled a kernel with ACPI=>Processor=>Thermal Zone enabled, but it doesn't seem to show anything in /proc/acpi on this machine. Again, many thanks for your suggestions. I must say the machine seems to be running faster under i386 than it did under x86_64, though that may just be an impression because I am not waiting for it to crash! -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
