my pch fan spinning normally when i turn on my pc this morning but suddenly it stop spinning after 6 seconds. when i reset and check the bios setting the pch fan shows n/a. my window boot normally but the pch fan won't spin. when i turn my pc off and unplug it then do the cmos clear. then plug it back and turn on my pc still my pch fan spin only for 6 seconds. My pch temp shows 41 degree celcius. Im currently using window 8 with Bios version 4102 and the mobo LED keep showing the 04 code. Anyone have any idea how to solve this matter?
