Summary 4:36-4:51 In this lesson, we discussed measures you can take to troubleshoot hardware devices. We discussed checking the basics first, verifying devices were detected by the BIOS UEFI, verifying devices are recognized in device manager, isolating the problem using known good hardware and solving device driver issues. Troubleshooting Devices 0:00-2:14 In this demonstration, we're going to talk about some things you can do to troubleshoot devices and device drivers. Now I always I tell folks that when you're troubleshooting devices and device drivers, always check the obvious first. For example, make sure that the device that you're having problems with is actually plugged all the way into the slot. If it's a PCI card, make sure it's fully seated. If it's a USB device, make sure it's fully seated into the USB slot. That will save a lot of problems, because frequently that is the issue. Also if it's a powered device, in other words, a device that needs external power, make sure it's plugged into a wall outlet. Now after checking the obvious, and the device still doesn't work, there are additional steps that you can take to try to troubleshoot the problem. In this example, I'm going to launch Device Manager because I have plugged a video capture device into my system and notice down here in Device Manager, what the results were. Windows detected that something was connected to a USB port, but it doesn't know what it was. If I right-click on these two devices, we see that the devices for this device are not installed, and there are no compatible drivers available for this device. Now you'll notice that it shows two different video capture devices. And you might be wondering why this is the case. For some hardware devices, you'll see one entry in Device Manager. For other devices, you'll see two. In this case, because it's a video capture device, we have one device for capturing video, and we have a second device for capturing audio. So we actually need to troubleshoot two different device drivers for this one device that's connected to a single USB port. If I right-click on the second device, I see that I have the same error displayed. The drivers for this device are not installed. Well, what do we do at this point? In this example, I'm going to check the documentation that came with this device in the box, and I find the manufacturer's website. And I also see a list of system requirements. And I see on the box that it lists Windows 7 as a system requirement. Well that tells me that this device was made quite some time ago. I'm running Windows 10 here and even though I installed the drivers that came on the disc with the device itself, the fact that I'm getting this error tells me that those drivers are not supported under Windows 10.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
