BIOS is the latest version. I didn't mention it, but my mobo is an MSI K8N
Neo4 Platinum, CPU is an Athlon64 X2 4200+. I also disabled CPU spread
spectrum in the BIOS, since some people report that that can interfere
with timing. It didn't help.
It would be useful to run another OS for a few days on this host, to see if
the problem occurs there too. But I don't have another OS installed, and
this host is my gateway and file server so it's not easy just to switch
OSes. Another possibility would be to run a 32-bit Linux kernel on it for
a while. That could be done, but again would require a whole new OS
I do wonder if this is a BIOS problem, since you say a BIOS upgrade fixed
the problem for you. I can write to MSI about it, but won't hold my
breath for a new BIOS update to fix it :(
