A USB notification does not by itself prove the device has failed. Device Manager status and a controlled port test help separate causes.
Protect your files first
Back up important files when possible. If the drive is encrypted, locate the BitLocker recovery key before recovery changes. Stop if storage appears to be failing or this is a work or school managed PC.
What to record
Device type, Device Manager code, USB port, cable, and whether another PC recognizes it.
The exact message, Windows version, and whether the desktop still opens matter more than a guess based on the symptom name.
Try these safer checks
Try a known-good cable or port when safe; inspect Device Manager and use the maker’s official support page for the exact device.
Change one thing at a time. After each check, see whether the same symptom returns and write down what changed.
When to stop and get help
Do not reconnect a damaged cable or device with overheating signs.
If this is a work or school device, contact its administrator before changing managed settings.
Keep track of your checks
