first let me tell you the important parts ithink u should know i have. my hdd is a seagate 7200.9 160gb sata hdd, and my mobo is a abit fatal1ty fi90-hd (the micro atx one). the case i have is an ultra microfly. after my comp is on for a couple hours the hdd activity light stays stuck on. i want to know how to fix this and how to prevent this if possible, thanks. the connection between the light and the mobo is tight as can be btw.
