that's certainly a plan to take.

i've heard reports of ecc and dual-core AND 64-bit playing
not-so-nicely together.

i think before everything you should run some stresstests from a
bootdisk and so forth. i'm not convinced it's not something hardware
as opposed to configuration.

has this been a persistent or recent problem?
