USB, Ethernet Ports not working properly after a recent memory upgrade.

It seems like the screenshot you've attached highlights issues with your network adapter where the status states "Not present". This could be a driver-related issue that's causing your volume keys and network icon to malfunction as well. Here are some steps you can try to troubleshoot and potentially resolve these issues:

Network Adapter Issue:​

1. Check Device Manager:
   • Open Device Manager and check under "Network Adapters" to see if your network adapter is listed. If it has an exclamation mark or a red X, there might be a driver issue.
   []Reinstall Network Adapter Driver:
   • Right-click on your network adapter in Device Manager, choose "Uninstall device," then restart your computer. Windows will reinstall the driver upon reboot.
   []Update Network Adapter Driver:
   • Visit the manufacturer's website for your laptop or network adapter, download the latest driver, and install it manually.

     Volume Keys Issue:​

   []Check Audio Driver:
   • Similarly, ensure that your audio drivers are up-to-date in Device Manager.
   []Reinstall Audio Driver:
   • You can try uninstalling the sound driver, restarting your system, and letting Windows automatically reinstall the driver on startup.

     General Troubleshooting:​

   []Windows Update:
   • Make sure your system is up-to-date with the latest Windows updates. Sometimes, updates can fix driver-related issues.
   []System Restore:
   • If the issues occurred right after the memory upgrade, a System Restore to a point before the upgrade might resolve the problems.
2. Hardware Check:
   • Ensure all components are properly connected, especially after a memory upgrade. Loose connections could lead to malfunctions.

     Contacting Support:​

     If the issues persist after trying these steps, consider reaching out to your device manufacturer or Microsoft Support for further assistance.
