Oi, i suggest you flash your bios and get the latest legacy drivers from viaarena.com . I have an old box which i think is a 686B never had data loss as you describe however i've noticed that the VIA chipsets sucks as compared to the nvidia chipset on x86 atleast, not as much as the laptop ati chipset. i always considered via to be quite stable :S Secondly, dont use windows ^^
