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?

Did you recently update your bios?

And do you get into OS with any problem?

What happened with the new bios is there was some changes to the threshold of the fan settings.

I also have gone back to the 4004
