Hi:

See if these drivers work.

1st install the smbus controller driver and restart the PC.

This package contains the Intel Chipset Installation Utility and Driver for supported notebook models and operating systems. This utility enables the operating system to show the correct name for the installed Intel hardware in the Microsoft Windows Device Manager.

PCI data acquisition and signal processing controller:

This package contains the driver that enables the Intel Dynamic Platform and Thermal Framework firmware. Intel Dynamic Platform and Thermal Framework provide system temperature and power utilization information for the system thermal protection to function properly. This package is provided for supported notebook models running a supported operating system.

pci simple communications controller:

This package provides the Intel Management Engine Interface (MEI) Driver for the supported notebook models and operating systems. The Intel Management Engine Interface enables communication between the host operating system and the Intel Management Engine firmware.

Try this graphics driver...

This package provides the driver that enables the Intel High-Definition (HD) Graphics in supported notebook models that are running a supported operating system. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver.

There can be one of several devices labeled as unknown.

After you install the above drivers, for any remaining device that still needs a driver, please post the hardware ID for the devices needing drivers.

Use this guide for how to find the hardware ID...

hi paul,

thanx a lot for the quick reply.

but i have already tried these drivers. but all wain. even when i finished the driver installation, then system dont ask for any restart of system. i am using windows 7 ultimate (2009). i think these drivers are latest updates and may be are not compatible with this old windows version. in device manager, VGA graphics card is not showing any problem, but in control panel programs, VGA graphics instalation not showing. and all these bad things are happening with me from yesterday. i have OBS STUDIO, WINDOWS MOVIE MAKER softwares in my notebook. now these are not running, showing crashed.

but before yesterday, all these softwares were running properly.

plz help, how to fix it.

Youre very welcome.

You might be right about that.

I suggest you reinstall W7, and update directly to SP1 before installing any drivers.

You can download the standalone SP1 update from the link below.

You want this file...

windows6.1-KB976932-X64.exe   903.2 MB

Those are definitely the drivers you need for those devices, so that would be the only suggestion I can offer.
