The Southbridge handling SATA, USB, and audio/LAN functionalities. 2.3 Super I/O and BIOS
A common check is testing the BIOS chip. As noted by some users, check pin 8 for standard 3.3V power (note: some schematics show 1.8v or 3v depending on the exact chip revision). Standby Voltages: Check for 5Vsb5 cap V sub s b end-sub on the Southbridge and Power button connector. 3.2 Troubleshooting Steps
