A reader asks: “How do I test for hardware driver conflicts?”

In Windows, it’s easy!

Open Device Manager by your preferred means (e.g. use search/run/cortana and enter “device manager” or “devmgmt.msc”; or open device manager in Control Panel/Devices and Printers/device manager; etc.). See Fig 1.

Fig. 1: Windows’ Device Manager lets you see your PC’s
hardware devices; you can expand any listed item for more info,
including its driver’s properties.

To make sure you’re seeing everything, click View, and select Show hidden devices. Fig 2.

Fig. 2: To make sure you’re seeing everything, click View,
and select Show hidden devices.

Scroll down the list of devices: If any device or its driver is having trouble , the device’s icon will be flagged with an obvious yellow exclamation point.

If a device or its driver is dead/broken/not working, its icon will be flagged with an obvious red X.

You can expand the listing for any flagged item — just click on it — and you’ll see additional info on the item, its driver, and any errors.

(I’d show you an image of the red X and yellow exclamation point; but nothing on my system is currently malfunctioning! <g> With luck, soon, nothing will be malfunctioning on your system, too!)
