It says us that problem is around ICs

It says us that problem is around ICs such as SIO and SouthBridge, because they take important role in processes of MoBo's starting.
Firstly, try to answer on two questions:
- Is any voltages on pins PWSW of motherboard? You can find these pins on the front panel connector.
- Where PWSW pins connected: to SB directly or SIO?
