This is a device driver related trouble that should be fixed and prevented by PC users before it results in computer malfunctions, computer hang-ups, Blue Screen of Death (BSoD), and random computer restarts. This article will discuss what an unknown device error code 43 is together with several causes leading to this hardware device trouble, and how to fix it.
What is Error Code 43
Unknown
Simply put, Unknown Device Code 43 is defined in Device Manager as a device problem with the error code 43. The error code 43 states that "Windows has stopped this device because it has reported problems (Code 43)." It is an error code common in Windows Operating Systems such as Windows XP, Vista, and Windows 7.
Causes of Unknown Device Code 43
Error code 43 problems may appear so suddenly, and they are due to corrupted or outdated device drivers.
- Corrupted Device Drivers: Corrupted drivers may trigger the Operating System to report problems, which in return will result in unknown device code 43 troubles. Device drivers can be affected by frequent system errors or by simple application errors and they can also be infected by computer viruses, which may corrupt or delete the drivers of a specific hardware device.
- Outdated Device Drivers: Outdated drivers can also trigger error code 43 troubles. This may happen when either a computer application detects bugs in the current device drivers or the existing drivers didn't meet the minimum requirements of a computer application.
Solutions for fixing Unknown Device Code 43
One of the solutions, which can fix an unknown device code 43 problem, is reinstalling the required drivers by using the drivers in an installation CD or a backup CD, but only if it's due to corrupted or deleted drivers. On the other hand, considering that error code 43 troubles can also be due to outdated drivers, it's highly recommended to update the current/existing drivers manually or by using reliable driver update software.
• Manual Update
In most cases, updating drivers online through the Update Driver option in Device Manager doesn't work for fixing unknown device troubles. On the other hand, PC users can still update their device drivers by downloading an updated version of device drivers online.
This option requires the Device type, model and the Device Manufacturer. The OS type must also be checked (if it's Vista, Windows 7, XP, et al, and if it's 32-bit or 64-bit OS) to prevent incompatibility issues.
In case the details of an unknown device with an error code 43 are incomplete or not available in the General tab of the device Properties, you can check in the Details tab for the hardware IDs. Browse and look for VEN_xxxx and DEV_xxxx. These IDs can be used as keywords in searching online, for example: the PCIdatabase website offers Driver Search and Vendor Search, which in return will provide useful information such as Device type, model, manufacturer, and even the official website of the hardware device manufacturer.
If you're doing a manual update, make sure to only download from the official website in order to prevent other device driver troubles such as downloading drivers bundled with computer viruses and spyware and wrong drivers. And, as mentioned, make sure to download drivers compatible with your OS type to prevent compatibility issues. Once the required drivers have been downloaded, go back in the Device Manager and follow these steps:
a. Right-Click the unknown device
b. Click Update Driver
c. Specify the locations of the downloaded drivers
d. Once the drivers have been found, follow the provided on-screen instructions
• Using a Driver Update Software
This option is recommended if you want to save your time and energy from the hassles and frustrations that come with identifying, finding, and downloading the latest compatible drivers manually. This option will let PC users update their existing device drivers automatically, and it will also take care of all the device driver issues (missing, corrupted, outdated, and incompatible drivers) on your computer.
As a recap, we see that an Unknown Device Code 43 problem can be caused by corrupted or outdated drivers, and it can be fixed by updating the existing device drivers. PC users can choose either a Manual Update or to use a sophisticated Driver Update Software, which will automate the process of updating the device drivers installed in a PC.
