You are running an Acer Product ID (PID) on a Gigabyte board.
This makes your installation counterfeit.
Troubleshooting a counterfeit installation is useless as it is not known what has been modified to your system.
A counterfeit installation contains heavily modified code which causes the system to behave in unexpected ways.
For this reason, analyzing counterfeit systems is unreliable and most analysts won't try it.
