About MSI CX420 Driver Downloads

The MSI CX420 is an older notebook model that may require original manufacturer drivers after a clean Windows 7 installation. Windows may install basic generic drivers automatically, but some notebook-specific components may remain unidentified or may not provide their full functionality until the appropriate driver is installed.

This page preserves the legacy download addresses used by the original MSI CX420 driver listing. The URLs are kept unchanged so readers who are maintaining an older installation can continue to use the original manufacturer-hosted package locations where those files remain available.

Important: Driver compatibility depends on the exact hardware configuration and Windows architecture. Do not install every package simply because it appears in the list. Use the hardware identification steps below when multiple drivers are available for the same category.

Windows 7 32-bit and 64-bit Compatibility

The original article title targets both Windows 7 32-bit and Windows 7 64-bit. However, individual legacy driver packages can have their own architecture and hardware requirements. Always read the package information before installation.

To check the Windows 7 architecture installed on your notebook, open Control Panel > System and Security > System and look at System type.

Tip: If a device is still shown as an unknown device after installing a seemingly correct driver, use Device Manager and compare its Hardware Ids with the hardware supported by the package.

MSI CX420 Driver Download List

The following sections retain the original MSI download URLs from the legacy CX420 driver listing.

TouchPad Driver

The Synaptics TouchPad package is intended for the notebook's touchpad input device. Install this driver when Windows does not provide the expected touchpad functionality or advanced settings.

Name	Version	Size	Download
Synaptics TouchPad Driver	16.3.1.2	46.26 MB	Download

Wireless LAN / Wi-Fi Drivers

The original CX420 listing contains multiple Wireless LAN packages. This is important because the exact wireless adapter can vary between notebook configurations. Do not install all WLAN packages together. Identify the installed wireless device first.

Name	Version	Size	Download
Atheros Wireless LAN	9.2.0.458	17.58 MB	Download
MSI Wireless LAN 6890 / 6891	3.1.8.1	1.58 MB	Download
MSI Wireless LAN 3870 / 3871	3.0.11.0	1.58 MB	Download

Wi-Fi identification tip: If one Wireless LAN package does not recognize your adapter, do not repeatedly install unrelated packages. Open Device Manager, locate the network adapter and check its Hardware Ids.

VGA / Graphics Driver

The CX420 driver listing identifies an ATI Mobility Radeon HD 545V / 5470 graphics package. Installing the correct graphics driver can restore the notebook's proper display adapter identification and graphics functionality.

Name	Version	Size	Download
ATI Mobility Radeon HD 545V / 5470	8.710.0.0000	195.05 MB	Download

Display check: After installation, open Device Manager and check Display adapters. The graphics device should no longer appear only as a generic Microsoft display adapter when the correct driver is installed.

Bluetooth Driver

The legacy listing includes a Bluetooth package for MSI Bluetooth hardware identified as 3801 / 3870 / 3871.

Because Bluetooth hardware can differ between notebook configurations, verify the installed device before applying this package.

Name	Version	Size	Download
MSI Bluetooth 3801 / 3870 / 3871	3.0.2.280	67.95 MB	Download

Audio Driver

The original driver listing identifies a Realtek HD Audio package for the MSI CX420. The audio package is relevant when the internal speakers, microphone or other Windows audio functions are not correctly recognized after reinstalling Windows.

Name	Version	Size	Download
Realtek HD Audio	6.0.1.6251	103.19 MB	Download

Audio troubleshooting: After installation, restart Windows and check Sound, video and game controllers in Device Manager. Also verify that the intended playback device is selected in Windows sound settings.

Card Reader Driver

The ENE Card Reader driver is included for the notebook's supported memory-card reader hardware. This driver can be useful when the card reader is not properly detected after Windows 7 installation.

Name	Version	Size	Download
ENE Card Reader	5.89.0.71	1.15 MB	Download

LAN / Ethernet Driver

The Realtek LAN package is intended for the notebook's wired network controller. Ethernet is particularly useful after a clean Windows 7 installation because it can provide an internet connection while other drivers are being installed.

Name	Version	Size	Download
Realtek LAN	7.011.1127.2009	5.33 MB	Download

Chipset Driver

The Intel 5 Series Chipset package belongs to the core platform driver set. Chipset drivers are normally installed early in a clean Windows installation because they help Windows correctly identify and manage motherboard-related hardware.

Name	Version	Size	Download
Intel(R) 5 Series Chipset	9.1.1.1027	2.33 MB	Download

Recommended MSI CX420 Driver Installation Order

A clean Windows 7 installation is usually easier to troubleshoot when the major platform drivers are installed before optional utilities. The following sequence provides a practical workflow for the drivers listed on this page.

Confirm that the notebook is the correct MSI CX420 model.
Check whether Windows 7 is installed as 32-bit or 64-bit.
Install the Intel 5 Series Chipset package.
Install the ATI Mobility Radeon HD 545V / 5470 graphics package.
Install the Realtek HD Audio package.
Install the Realtek LAN driver if Ethernet is not automatically recognized.
Identify and install the correct Wireless LAN package.
Install the Bluetooth package when the corresponding hardware is present.
Install the ENE Card Reader driver.
Install the Synaptics TouchPad driver.

After installation: Restart the notebook and check Device Manager for devices with warning icons or devices still listed under "Unknown device".

How to Find the Correct MSI CX420 Driver

If you are unsure which Wireless LAN, Bluetooth or another hardware package should be installed, Windows Device Manager can help identify the exact component.

Open Device Manager.
Find the device with a warning icon or an unknown-device entry.
Right-click the device and choose Properties.
Open the Details tab.
Select Hardware Ids from the Property list.
Compare the hardware information with the driver category you are trying to install.

Why this matters: The original CX420 listing contains three Wireless LAN packages. Installing the wrong WLAN driver can fail even though the package itself is valid for another compatible MSI wireless device.

MSI CX420 Windows 7 Driver Troubleshooting

Wi-Fi is not working after Windows 7 installation

Check Device Manager and identify the exact wireless adapter first. The driver list contains several WLAN packages, so the correct package depends on the hardware configuration.

If the adapter is completely absent, also verify that the wireless hardware is enabled in the notebook.

No sound after installing Windows 7

Confirm that the Realtek HD Audio device appears correctly in Device Manager. After installing the audio driver, restart Windows and check the selected playback device.

Graphics adapter is shown as a generic Microsoft adapter

Check the Display adapters section in Device Manager. If Windows is still using a generic display driver, install the appropriate ATI Mobility Radeon package listed on this page and restart the notebook.

Bluetooth is not available

The Bluetooth package should only be installed when the applicable Bluetooth hardware is present. Verify the device in Device Manager before choosing a package.

Card reader is not detected

Verify the card-reader device under Device Manager. If it is listed as an unknown device, inspect its Hardware Ids and then install the ENE Card Reader package.

One driver package does not install

Do not assume that the package is defective. First check the Windows architecture, the exact CX420 model and the hardware device being targeted. Legacy drivers can be specific to a particular hardware component or system configuration.

Tips Before Installing Legacy Drivers

Create a Windows restore point before installing several legacy drivers at once.
Install one major driver category at a time when troubleshooting.
Restart Windows when the installer specifically requires a reboot.
Keep a copy of the original downloaded ZIP files for future reinstallations.
Do not flash BIOS or firmware simply because a normal Windows driver is missing.
Use Device Manager Hardware Ids when more than one package appears suitable.
