device manager warnings

Device Manager warnings on Windows can indicate driver faults, failing hardware, or malware. Common signs include yellow exclamation marks, error codes, or devices showing as not working properly. These warnings often accompany other symptoms like idle resource spikes, overheating, post-update slowdowns, or blue screens. Ignoring recurring Device Manager warnings may lead to data loss or system instability. Windows provides telemetry and health warnings that help diagnose issues early. Addressing these warnings promptly can prevent more serious problems.
