Hello everyone hope you are doing well,
i have a ddr2 I31GM4-LF REV3.0
it seems everything working fine except that USB,SATA,PCI Devices can not be read or detected by the computer but the strange thing that there's voltage present like the usb 5v and the pci 3.3v i believe its something related to the southbrgide chip.
as i know if the southbridge is faulty the pc will not turn on in the first place.
by the way i did replace couple cup's and rams and they works fine. and i did check mosfets and caps and they are good.
i don't know what to check else i'm stuck
so i hope if anyone else saw a problem like this before or have tips or solutions for me.
i know the motherboard don't worth fixing it it's only for the purpose of learning.
best regrades ^^
