Post-Installation Blues: Tackling USB Hard Drive and Connectivity Issues in Windows 10


“Following a recent Windows 10 installation, I’ve encountered persistent issues with my external USB hard drive, which fails to be recognized when connected to a PCIe x1 USB expansion card, yet functions normally via motherboard USB ports. Additionally, my system experiences sporadic freezes, after which I lose internet connectivity and the hard drive disappears from ‘My Computer’, particularly while accessing files on it. Attempts to soft restart result in indefinite hangs on the ‘Restarting…’ or ‘Shutting down…’ screens, necessitating a reset button press or hard shutdown for recovery. What could be causing these problems, and how can they be resolved?”


This article addresses the common issues faced by users after a fresh Windows 10 installation, particularly involving external USB hard drives and system stability. We delve into the potential causes and provide a comprehensive guide to resolving these problems.


A fresh installation of Windows 10 can sometimes bring unexpected challenges. One such issue involves the system’s interaction with external USB hard drives and overall stability. Users have reported that their external USB hard drives are not recognized when connected to a PCIe x1 USB expansion card, though they work fine when plugged directly into the motherboard’s USB ports. Moreover, the system may experience sporadic freezes, leading to loss of internet connectivity and the disappearance of the hard drive from ‘My Computer’. These incidents often occur during file access and are followed by failed soft restart attempts, which get indefinitely stuck on the ‘Restarting…’ or ‘Shutting down…’ screens.

Identifying the Problem:

The root of these issues can be multifaceted. It could stem from driver conflicts, power management settings, hardware incompatibility, or system file corruption. The PCIe x1 USB expansion card may have outdated or incompatible drivers, or there might be a conflict between the card and the motherboard’s USB controllers. The system freezes and connectivity losses suggest a deeper problem, potentially with the power settings or system files.

Proposed Solutions:


Driver Update and Conflict Resolution:

  • Ensure that the latest drivers for the PCIe x1 USB expansion card are installed.
  • Check the Device Manager for any conflicts or warning signs next to USB controllers and resolve them.
  • Update the motherboard’s chipset drivers.
  • 2.

Power Management Optimization:

  • Adjust the power settings in Windows to prevent the system from turning off the USB ports to save power.
  • Check the BIOS settings for any USB-related power options that might be affecting stability.
  • 3.

Hardware Compatibility Check:

  • Verify if the PCIe x1 USB expansion card is fully compatible with the motherboard.
  • Test the external USB hard drive with another system to rule out drive-related issues.
  • 4.

System File Check:

  • Use Windows’ built-in System File Checker (SFC) tool to repair any corrupted system files.
  • If SFC doesn’t resolve the issue, consider using the DISM (Deployment Image Service and Management Tool) to repair the Windows system image.
  • 5.

Hard Reset and BIOS Update:

  • Perform a hard reset by shutting down the computer, unplugging all peripherals, and holding the power button for 15-20 seconds.
  • Check for any available BIOS updates that might address USB stability issues.


Persistent issues following a Windows 10 installation can be frustrating, but they are often resolvable with systematic troubleshooting. By addressing drivers, power management, hardware compatibility, and system file integrity, users can restore functionality and stability to their systems. If problems persist, seeking professional technical support is advised.
