Windows cannot apply all of the properties for this device. Device properties may include information that describes the device's capabilities and settings (such as security settings for example). To fix this problem, you can try reinstalling this device. However,we recommend that you contact the hardware manufacturer for a new driver. (Code50)
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
Intel SMBus Controller device drivers are overwritten with Intel Chipset Device Software when updated through Microsoft Windows* Update, causing a loss of functionality for affected Intel SMBus Controller devices.1 This loss of functionality applies to Windows* 7, Windows 8, Windows 8.1, and Windows Server systems.
The SMBus is used for system management communications. If the device driver for the Intel SMBus Controller is not correctly installed, the temperature reporting, as an example, for the processor, PCH, and memory modules may not function as expected.
The existing Intel SMBus Controller device drivers are overwritten with the Intel Chipset Device Software, which provides the operating system with information about the device/hardware. This information allows the operating system to display the correct product name for that piece of hardware in Device Manager. The Intel Chipset Device Software does not install device drivers for the Intel SMBus Controller, resulting in a loss of device functionality.

This article expounded by MiniTool official web page mainly shows you five methods to handle PCI memory controller driver not working issue. Also, it introduces the definition of the PCI memory controller and provides a website to download its driver.
PCI, peripheral component interconnect, is an industry-standard bus for attaching peripheral devices to a computer. The PCI Simple Communications Controller is a generic label that Windows offers to install PCI boards in Device Manager when the drivers for the device are not installed.
PCI memory controller driver plays as a mediator between PCI memory controller devices including SD cards, cameras, or Intel Turbo Memory with your OS. Compatible versions of PCI memory controller drivers have to be installed in case of driver problems.
If the PCI memory driver not installed, a yellow triangle with a black exclamation mark within will appear on the PCI memory controller and the controller will locate under Other devices in Device Manager.
If the PCI memory controller driver missing or the PCI memory controller driver no driver, you can reinstall it on your computer. In the above right-click menu, choose Uninstall device. Then, restart the PC to let Microsoft Windows reinstall the correct driver for you.
It's challenging to give a single precise definition for the term driver. In the most fundamental sense, a driver is a software component that lets the operating system and a device communicate with each other.
For example, suppose an application needs to read some data from a device. The application calls a function implemented by the operating system, and the operating system calls a function implemented by the driver. The driver, which was written by the same company that designed and manufactured the device, knows how to communicate with the device hardware to get the data. After the driver gets the data from the device, it returns the data to the operating system, which returns it to the application.
For a given I/O request (like reading data from a device), there are often several drivers layered in a driver stack that participate in the request. The conventional way to visualize the stack is with the first participant at the top and the last participant at the bottom, as shown in this diagram. Some of the drivers in the stack might participate by transforming the request from one format to another. These drivers don't communicate directly with the device; they just manipulate the request and pass the request along to drivers that are lower in the stack.
For example, suppose you need to write a tool that has access to core operating system data structures. These structures can only be accessed by code running in kernel mode. You can do that by splitting the tool into two components. The first component runs in user mode and presents the user interface. The second component runs in kernel mode and has access to the core operating system data. The component that runs in user mode is called an application, and the component that runs in kernel mode is called a software driver. A software driver isn't associated with a hardware device.
Software drivers always run in kernel mode. The main reason for writing a software driver is to gain access to protected data that is available only in kernel mode. However device drivers don't always need access to kernel-mode data and resources. So some device drivers run in user mode.
Our explanation so far oversimplifies the definition of function driver. We said that the function driver for a device is the one driver in the stack that communicates directly with the device. This is true for a device that connects directly to the Peripheral Component Interconnect (PCI) bus. The function driver for a PCI device obtains addresses that are mapped to port and memory resources on the device. The function driver communicates directly with the device by writing to those addresses.
However in many cases, a device doesn't connect directly to the PCI bus. Instead the device connects to a host bus adapter that is connected to the PCI bus. For example, a USB toaster connects to a host bus adapter (called a USB host controller), which is connected to the PCI bus. The USB toaster has a function driver, and the USB host controller also has a function driver. The function driver for the toaster communicates indirectly with the toaster by sending a request to the function driver for the USB host controller. The function driver for the USB host controller then communicates directly with the USB host controller hardware, which communicates with the toaster.
In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used. 153554b96e
