Identify the exact device
Open Device Manager and note the device name, manufacturer, error symbol, and error code. Do not install a driver intended for a merely similar device.
Prefer trusted driver sources
Use Windows Update or the computer, motherboard, or component manufacturer’s official support page. Avoid anonymous driver-download sites and bundles.
Roll back a recent driver
If the problem began immediately after an update, open the device properties and use Roll Back Driver when available. Restart and test before making another change.
Reinstall the device safely
Uninstall the affected device in Device Manager, restart, and allow Windows to rediscover it. Do not select removal of the driver package unless you already have the correct replacement.
Know when the problem is hardware
A device that disappears repeatedly, overheats, disconnects physically, or fails on another computer may need hardware service rather than another driver.
These steps provide general educational guidance and cannot guarantee a repair. Software cannot physically repair failed storage, damaged memory, overheating components, broken connectors, or liquid damage.
