Memory Upgrade:

This system supports 2 GB of RAM (2×2 GB Modules). This can also be purchased using the affiliate link above.

Media Direct

Media Direct should be installed before the Operating System in order for the Media Direct Button to function correctly.

Operating System

It is recommended to install Windows 10 on this system see Windows OEM FAQs and Downloads. The Windows Vista OEM or Windows XP Product Key won't be compatible with Windows 10 Installation Media however you can run Windows 10 Unlicensed. Windows 10 will have most of the system drivers required inbuilt however you can install the Windows 7 Drivers if you have any unknown Devices in the Device Manager.

  1. I am going to use this post as a guide for my Dell upgrade to Windows 8.1. Thank you really really much! :))

  2. Really helpful. My Inspiron 1420 was out of audio after installing Windows8.1 and I was googling for the last 2-3 days for a solution installing almost all available drivers. Now I installed the driver provided and the audio works now. Thanks

  3. my inspiron 1420 still out of audio after installing windows 7 32bit. which audio drivers i have to install?

  4. "For Windows 8.1 the audio driver is inbuilt to the OS". Yes that is true but the speakers do not create sound.

      1. Yes fresh install of windows 8.1 64. The default playback device was set. But I managed to get the audio working by installing the reg file and the audio driver: R171786.exe
        Great website.

  5. In my Dell 1420 fresh install 8.1 x64 all your drivers run like a charm, thanks a lot
