eek the case of "my friend told me this".. well sorta, there is a known issue with SBLive cards and the Via686B southbridge... but if ur friend read the whole article, he'd know there has since been a fix for it, hehe..
http://www.viahardware.com jus download the latest via4in1, 4.32 i think.. and you shouldnt have problems due to that.. good luck..
