Sometimes the errors that appear on our screen PC Windows are unclear and disconcerting. However, others explain directly what is happening. In this article we tell you How to fix “Windows has stopped this device because it has reported problems” (Code 43) error.

Specifically, this error appears when the operating system detects the malfunction of a hardware component or a connected external deviceThis makes it considerably easier to locate the problem and apply the appropriate solution.

In short, most common causes that give rise to error code 43 are the following:

• Corrupt or incompatible drivers.
• Hardware failures, either due to physical damage or internal problems.
• Outdated firmware.
• Operating system problems, from compatibility conflicts to incorrect configurations or conflicts.

Below is the list of solutions. Our recommendation is that, if you encounter error code 43, you try each of them in the same order in which we present them here:

Preliminary checks for code 43

Before starting to search for solutions to error code 43, it is necessary to rule out a series of causes that, as obvious as they may seem, can often be overlooked.

The first thing to do is verify that the connections are in place. If we are talking about external devices, we can disconnect them and reconnect them again (for example, if it is a USB, try a different port), in addition to check that the connection cables are in good condition.

As for internal devices, such as the graphics card, this check can be performed turning off the PC and taking a look inside the PC.

Another thing we can do is (in case of external devices), try connecting them to another computer, to see if the problems still occur. It is also very useful to use the old trick of Restart your computer. Many times, that's enough to get everything working as it should again.

Update drivers

Once the most obvious reasons have been ruled out, you need to try solve error code 43 through the classic procedure of updating the drivers. In a large number of cases, this will solve the problem. Here is how we should proceed:

1. To begin with, We open the Device Manager using the keyboard shortcut Windows + X and selecting this option from the list.
2. After We look for the device where the error is located (usually marked with a yellow exclamation mark).
3. Next, we right-click on the device and select the option "update driver«.
4. Finally, we select «Search for drivers automatically«If this method does not work, we will have to download the driver from the manufacturer's official website to install it manually.

Another way to fix this error more directly is uninstall the device where the error is registered and reinstall it from scratchTo do this, we need to go back to the Device Manager, right-click on the device with the error and choose the option “Uninstall device”. Once this is done, just restart the computer so that Windows automatically reinstalls the device.

Update Windows

• To start, let's go to Settings menu from our PC.
• There we choose the section "Update and security".
• Select the option Windows Update.
• Through this tool we can perform all pending updates, which often include patches to fix hardware and driver issues.

It is also important update the firmware of the devices, since some of them require it to function properly. We should not neglect the BIOSIf this is outdated it could lead to incompatibilities such as error code 43. It is best to check the manufacturer's website to see if any updates are available.

Physical damage to hardware

When problems persist despite having tried all the previous solutions, you have to start considering whether there are physical damage to any of the hardware components. Sometimes this damage is clearly visible, but other times it takes an expert eye to detect it.

A good method to locate these damages is to use the Events viewer (it can be accessed using the keyboard shortcut Windows + X). With this tool we will be able to search for events related to the problematic device and thus obtain more details.
