Unknown Device & Network Controller in the Device Manager for Lenovo G450

Hi, In My lenovo G450- with Intel Chipset - 3GB RAM (no external graphics card),

am seeing a Unknown Device with question mark on device Manager, running on Win XP. Further clicking on Device properties tell me that -

Device type : Other Devices

Manufacturer: Unknown

Location : On Microsoft ACPI- Compliant Embedded Controller.

 

I have installed all the drivers and have not installed any external devices like USB etc.

Am not getting which device this could be.

 

Network Controller also shows with question mark even after installing Broadcom Ethernet Driver for XP.

 

Kindly help me what to do?

Is there any order where we need to install the drivers.
