You can fix it by installing the latest chipset drivers for your computer. This problem is common among computers with Intel and AMD chipset.

1. First download the latest chipset drivers.

Intel Chipset / SM Bus Controller Driver: Intel chipset Installation Utility
AMD Chipset : AMD SM Bus Driver 

2. Install the drivers and wait until the installation finish.

3. Restart your computer after installation finish.

Your laptop or motherboard manufacturer also provide the chipset drivers on their support site. However installing the drivers from Intel or AMD is recommended since they always provide the latest drivers available.

Where to Download AMD Chipset?
For Intel you does not have to choose the chipset because Intel provide one software to install any Intel chipset/SM Bus controller driver. Downloading AMD chipset driver is not easy if you are not used with the website interface, you need to go to AMD Download center here:

http://support.amd.com/en-us/download

Then select the chipset with the right operating system. Then click display results.  Refer to the pictures below:

You can check your chipset series by looking at your motherboard or laptop specification or choose not sure from the drop down menu.

You will not notice a significant change on your system after installing the SM Bus Controller Driver. However it is important to maintain your Windows Operating System Stability.

How to Install and Fix CSR Bluetooth Driver

CSR Bluetooth is one of the common Inbuilt Bluetooth devices on most laptop, desktop commonly uses the CSR Bluetooth dongle since most desktop does not have the inbuilt Bluetooth device. What you need to do basically install the drivers CD (that come with it when you buy it) or get the Bluetooth drivers from your notebook/device manufacturer.

This method worked for:
-Windows XP, Vista and Windows 7. Not yet tested with Windows 8.
-CSR and other Bluetooth device.

BLUETOOTH STOPPED WORKING

 BUT, sometimes, even the drivers installed properly, your Bluetooth still does not work. This is the most common problem for CSR Bluetooth devices. The main culprit normally Windows Update. Windows automatically installed a new driver but the truth it is unstable and cause your Bluetooth not working properly. You can also applied the method I described below with other Bluetooth device such as Atheros, Ralink, Broadcom and Realtek. The main reason I make this post specifically for CSR is unlike other Bluetooth devices manufacturer, CSR doesn't seem to have a support site where you can download the stable drivers. So there are 2 ways to solve this:

BEFORE WE START:
1. Make sure to plug in your Bluetooth dongle.
2. For inbuilt bluetooth (commonly for laptop), turn on your bluetooth by pressing the Fn key + Bluetooth key. (look for the bluetooth symbol on your keyboard).

STEP 1: ROLL BACK DRIVERS

click on the picture to enlarge

• Open device manager, look for your Bluetooth Icon,
• Right click on it and select properties
• select drivers tab
• and select roll back drivers,

If the rollback driver options is not available, proceed to STEP 2.

STEP 2: REINSTALL GENERIC BLUETOOTH DRIVER

This method work most of the time especially for those who installed a newer version of the driver (for example the drivers from the windows update). Windows actually have a generic bluetooth drivers which can be use with any bluetooth device. So not to worry if you lost your original driver backup or Drivers CD.

FOR CSR BLUETOOTH
 Open device manager and look for Universal Serial Bus Controller. Click the arrow to expand the list  and you will see CSR BluCore Nanosira listed if you use nanosira Bluetooth.

FOR OTHER BLUETOOTH
Normally for notebook such as ACER, HP and ASUS, or you are using other Bluetooth brand, you will see your Bluetooth listed under Bluetooth or other devices in device manager. you will also see a yellow exclamation mark on it.
(Don't worry if you see too many of them, normally when you install the driver once, all the other will gone - automatically installed).

INSTALLATION

• Right click on the Bluetooth device and select Update Driver Software. 
• Then select Browse my computer for drivers software and then 
• "Let me pick form a list of device drivers on my computer".

Now you will see a Generic Bluetooth radio from the list. Select it and continue with on screen instruction until installation Finish. Sometimes it is listed as Generic BT drivers.

Now you will be able to use your Bluetooth again.

HP Pavilion ZE2000 Windows 7 Drivers

Windows 7 and Pavilion ZE2000

Windows 7 will automatically install the drivers you need. The main problem is you will need to install the graphic driver to get the maximum resolution and performance and also the audio drivers. This is because most ZE2000 uses Intel 82825/82855 GME graphic chipset which no official Windows 7 drivers released by Intel or HP. Further more, all ZE2000 model/variants uses Conexant AC-Link which does have an official support site which provide newer driver for old sound chipset.

ZE2000 Windows 7 Drivers

Actually you only need to use the original Windows XP drivers, but it require a little bit modification before installation.
I already write a brief installation guide to install both audio and graphic drivers.

Audio Driver for Windows 7. : Drivers and installation
Graphic drivers: Drivers and installation

Others Drivers Installation

If you have problems with the other driver do let me know. From my experience you will also need to install Card reader driver (if you want to use it). You can also use your original XP driver, just install it in compatibility mode or use the same audio installation method to install the card reader.

You wifi should work because from my experience windows will automatically installed the driver for it. Do let me know if you have problems with the driver installation.
