The only problems I have seen with AMD systems were not related to the CPU but the chipset. The VIA chipsets that most of the amd systems us have problems with the drivers. It may pay to update to the latest 4 in 1 drivers from www.viatech.com if that system does in fact have a via chipset.

There is a known problem with data loss on some machines that use an older version of the bus mastering driver for the hard drives.
