Hello , i have a FIC PA-2013 motherboard , i wanted to put in a new system, the board was working fine for 30 minutes , after that it started freezing and had to restart to make it work, and made a squeeking noise at the cpu capacitors ( the small SMD capacitors in the middle of the socket ) , suddenly the cpu fan stoped and turned on and did this a couple of times , after that the cpu fan socket ( 3 pin ) wasnt recieving 12V , so i had no more cpu fan spinning , after that the board just froze and died .
Now the motherboard wont post at all ...
So basically i identified a mostfet that is really hot, near the battery , its a 9435A -30V P-Channel Enhancement Mode MOSFET.
I uploaded 2 pictures where the hot mosfet is .
What i've done :
I replaced the 9435A also the 51031 ic and the diode
Recapped all main capacitors with new ones.
Checked for any short ( ive checked all small smd capacitors , none of them are in short )
Replaced 3 cpu-s
Tried with 2 power suplies
Tried with at least 10 memories
Cleaned the board
North bridge and South bridge look good because i cannot identify any short.
Checked the 2 VRM-S near the CPU , not in short .
Removed all main capacitors like 13 of them and started the board without them ( mosfet still getting hot )
And yes the jumper settings for the cpu are okay.
Checked for any dirt between ( Sdram slots , agp , pci )
Anybody can come up with some ideeas , because i have kinda ran out of them
Come lets ressurect this board , its the best motherboard in the world for the socket 7 platform, a holy grail ! , it would be a shame for it to die
