• Look for any devices with a yellow triangle or error message, especially near your USB devices. Right-click and select Uninstall Device if you see any error. Then, restart the laptop to let Windows reinstall the drivers.

2. Update USB Drivers

• In Device Manager, right-click each USB driver under Universal Serial Bus controllers and select Update driver.
• Choose Search automatically for updated driver software.
• Also, visit HP's support site and download the latest chipset and USB drivers for your laptop model.

3. Run Windows Troubleshooter for Hardware and Devices

• Select Hardware and Devices and Run the troubleshooter. Follow the on-screen instructions to resolve any detected issues.

4. Check Power Management Settings for USB

• In Device Manager, right-click on each USB Root Hub (in Universal Serial Bus controllers) and go to Properties > Power Management.
• Uncheck Allow the computer to turn off this device to save power for each USB Root Hub.

5. Update BIOS and Windows

• Check HP’s website for any BIOS or firmware updates for your Victus model, as these can sometimes resolve hardware compatibility issues.

6. Test USB Devices Individually

• Connect your USB devices one at a time to see if a specific device causes the issue to reoccur.
• If any USB device triggers the issue, try using it on another computer to confirm if the device itself might be faulty.

7. Run System File Checker and DISM Commands

• Open Command Prompt as an administrator.
• Run the following commands one by one:
  • sfc /scannow
  • DISM /Online /Cleanup-Image /RestoreHealth
• These commands can repair any corrupted system files that may be affecting your USB, audio, or general stability.

8. Check for Overheating or Power Supply Issues

• Overheating can sometimes cause USB issues and freezing. Ensure that your laptop has proper airflow.
• If you’re using external peripherals that draw a lot of power, try disconnecting them temporarily to see if the issue persists.
