A USB flash drive can crash a computer due to several reasons, including corrupted or incompatible file formats, insufficient storage capacity, and overheating.

This issue is further exacerbated when you try to eject the drive, causing the tab to malfunction and leading to a PC crash.

⚠️ Common Causes

  • Corrupted or incompatible file formats, such as JPEG files with incorrect metadata.
  • Insufficient storage capacity on the USB flash drive.
  • Overheating of the USB port or the USB flash drive itself.
