There are such unpleasant situations when you are working at a computer, everything seems to be normal, but then suddenly, for no reason, the system gives a message that the device was stopped (code 43). Yes, the system does not hang, but it becomes almost impossible to work. Let's see what is the origin of such situations.
What is an error (code 43)?
Naturally, there can be many reasons for the occurrence of such failures. The appearance of a message about a stop of some equipment means only that Windows has detected a hardware conflict.
Moreover, this is not a failure of the operating system, as some users might think. These are precisely the conflicts between the “iron” components. Oddly enough, it happens. And it's often not even the drivers or related programs. For example, sometimes a device installed in the system may simply simply not have enough power, which provides the same computer system unit. Consider the most common options for the occurrence of such failures.
Most common situations
It is believed that the error code 43 manifests itself mainly in the event of a malfunction of the video card (video adapter, video accelerator, graphics accelerator). If you analyze the most common situations, the most common, unfortunately, are the conflicts of the graphics accelerator with the RAM slots.
The situation in the event of a malfunction (code 43) is interpreted by the system as a kind of “inanity” between the “RAM” of the computer and the memory of the video adapter. And, as it is believed, this does not directly depend on the device drivers, but on the manufacturers themselves, because in most cases the BIOS of a video card is determined in the sense that the device is recognized by the system, which means it should function normally. It would seem ... But no! There it was. How to fix the error containing code 43, we now see.
Fix video adapter problems
First you need to make sure that the device (in the sense of a graphics accelerator) is determined by the system, but does not function as it should.
To do this, you must use the standard "Device Manager" Windows. Here you will immediately see the status of the device. If it is marked with a yellow icon with an exclamation mark, it means that the device does not work correctly.
First, try to update the drivers for the video card or reinstall them. Who knows, maybe a conflict arose precisely at the software level (especially for plug-and-play Plug & Play devices). But what is most striking is the fact that NVIDIA adapters are, strangely enough, prone to the appearance of errors containing code 43.
RAM problems
Here you should first use the computer administration and additional boot options, which are accessed through the system configuration menu. In the line indicating the amount of memory you need to check the box next to the item that allows you to use its maximum, indicating the corresponding value in the desired field).
We overload the system and wait for the result. If the message appears again, you will have to remove all memory sticks when the computer terminal is turned off, and then insert no more than 2 GB, gradually adding new ones (if any).
It may well be that this is not connected at all with the video card, namely, the “RAM”, or rather, the slats from different manufacturers.
Problem (code 43) when using USB devices
USB devices are also not immune to the appearance of messages about such errors. Most often this applies to ordinary flash drives, and not to USB-hard drives. What could be more? Yes, they just accidentally hooked a USB flash drive into a port on a laptop. So the system “spat.” Just re-insert it into the appropriate port or just reboot the system.
Unidentified devices and registry clutter issues
Another thing is when Windows does not recognize the device (in the "Device Manager" it is indicated as Unknown Device).
This situation indicates that the system simply did not find in its arsenal the drivers that are most suitable for the correct operation of the device. In this case, you will either have to install the driver from the disk, or simply download it from the Internet (at least from the manufacturer’s official website).
In some cases, code 43 in a system error may also be due to the fact that the registry contains a lot of incorrect or outdated keys that the system refers to when trying to access a plug-in USB component. Everything here is also simple.
Since Windows itself does not have its own tools as such, you need to use utilities to fix the registry. It can be anything, say, programs like CCleaner, Advanced System Care, Glary Utilities, Windows 7 Manager, Ashampoo WinOptimizer, Registry Optimizer, in general, any optimizer where there is such a function, even included in the analysis and correction system in one click.
Total
In general, as is already clear, you should not be afraid of messages about the shutdown of some equipment. In principle, such problems, in most cases, are solved quite simply. Of course, now they do not take into account the situation when some kind of “iron” component fails completely or partially. Naturally, it will require its replacement with a new or similar one.
On the other hand, many experts do not recommend installing the same RAM slots from different manufacturers. As they say, you never know what. On the other hand, hardware conflicts can be based on a software level, so do not forget about system optimization tools, they often help much better than even replacing hardware, eliminating conflicts in terms of cross-device device drivers. True, this will require professional utilities. In general, errors can occur even in Bluetooth wireless modules.
