I suppose my previous answer wasn't *that* clear -- yes, my setup
mirrored yours down to the 64 bit install, with a 3200 processor. I don't
know if yours is one of the Socket 939 or Socket 754 variants, but that
*really* shouldn't matter (mine's a Socket 939). I *do* know that I'm
running on an NForce 4-based ASUS motherboard, whereas I think yours is
Via-based.

Have you tried turning off ACPI? The ACPI subsystem does use a lot of
stuff from the BIOS, which may well not have been debugged under a 64 bit
OS. (Just a thought...)

If you're willing to risk it, you could always see if *Asus* have an
updated BIOS. That should work on your motherboard.

Or stick with the 32 bit install.

Hope this helps,

James.
