What this section covers

Choose the symptom you can actually observe: missing sound, an unreliable connection, unexpected display behavior or a device status message. A symptom can have several causes. The guides below start with reversible checks and explain which observations justify investigating the driver next.

Symptoms that look like driver faults often have simpler causes: a cable, a muted setting, a power-saving option or a device that is switched off. Checking those first is quicker and changes nothing.

When the evidence does point at a driver, the device's status message and the date of the last change are the two most useful clues. Change one thing at a time so the result of each test is clear.

From symptom to cause

Testone change, then recheck

Narrowing the scope before changing anything avoids replacing a driver that was never the problem.

First checks

Rule out the simple causes

These checks change nothing on the system and often resolve the problem outright.

Restart the computer and the device
Check cables, power, batteries and the selected input or output
Try the device on another port or another computer
Look at the device's status in Device Manager and note any error code

Keep cause and correlation separate

A problem beginning after an update is useful timing evidence, not proof that the update caused it. Record one observable change at a time and compare the same connection, application and workload where practical. If a check would erase settings or remove a working device, pause until you have a recovery plan and relevant manufacturer instructions.
