How to Identify problems in the Windows Device Manager?
When you run the Device Manager, a screen shown in the example display below. Next to each gadget category, arrows are pointing to the right. No other devices or Unknown devices should be mentioned, and all categories should have Plus signs. However, if issues arise, you might be making one or more than one of the errors listed below.
Note: If you have a problem using the Device Manager, Windows may have corrupt files. To resolve this problem, it might be essential to conduct the Windows repair procedure using the Windows CD or DVD.
1) Exclamation mark or other devices
Under Other devices, if a gadget is marked with a yellow circle and an exclamation point, other hardware conflicts with it. It could also mean that the device's drivers must be incorrectly installed.
An error code is displayed when you double-click and open the problematic device.
A list of Device Manager error codes is provided below, along with suggestions for how to fix each one. To find your problem code, scroll through the entire list.

What to do with devices such as exclamation points or others?
You may remove any devices marked with an exclamation point and any Other devices from Device Manager by selecting them and hitting the delete key on the keyboard. After uninstalling everyone, restart the machine to allow Windows to re-check the devices.
Windows cannot install the devices if the Device Manager does not change even after restarting the computer because it lacks the necessary driver support. Make use of the hardware's original installation DVD or download the most recent drivers for that particular device.
Select the equipment
Before looking for drivers or software, know the device's maker and model. On the website of the manufacturer, you can find the software or drivers for an internal hardware component of an OEM computer. They might also be on a system-supplied CD or DVD.
2) Red "x"
The device has been deleted or disabled, or Windows cannot find it.
How to handle red X
Double-click the device marked with a red x if you want to enable it. At the bottom of the General tab, click the Device usage drop-down box next to "Do not use this device (disabled)," then select "Use this device (enabled)."
If this isn't an option or it's already enabled, select the device in Device Manager and remove it using the delete key. Allow Windows to re-check the device after a restart of the computer.
Windows cannot install the devices if the Device Manager does not change even after restarting the computer because it lacks the necessary driver support. You must use the original installation disc that was included with the hardware or download the most recent drivers for that particular device.
3) Down arrow
When a little down arrow is seen next to a device in Windows Vista, and later, it means the device is disabled.
Use of the down arrow
Double-click the device, select the Driver tab and then press the Enable button to fix the problem. If prompted, restart the computer after it has been activated.
Hardware not present or unknown device
Hardware that's missing:
The computer does not identify the device if you cannot install it and do not see it listed under "Other devices" in Device Manager. Windows should list the device under Other or Unknown devices even if it lacks the necessary driver support.
Try shutting down the computer, unplugging and replugging the hardware, and restarting it. If Windows can still not recognize the device, it is either defective or incompatible with your version of Windows.
4) Unknown device
Devices recognized but displayed as Unknown devices are those for which Windows lacks the necessary driver support.
When you haven't installed anything recently and are unsure of what the computer's unknown device might be, it can be challenging to identify it.
You can have more than one Unknown device in the machine if you recently performed several Windows reinstallations. The majority, if not all, Unknown devices should be resolved by installing the computer's chipset drivers from a CD or Download. Additionally, following the setup instructions on your driver CD might fix many issues with Unknown devices.
Run the setup or download the drivers from the supplied CD if you're trying to install a new device on your computer. If you don't have a driver's disc, you can download the drivers from the manufacturer's website.
