The most recommended upgrade for this system is a Solid State Drive, here is my affiliate link to Crucial here. If purchasing a SSD or Memory Upgrade please use these links as I will get a tiny bit of commission which will help fund my guides.

SSD Drive Upgrade

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.

  4. Hi!

    First of all, thanks a lot for this site! YOU ARE THE BEST!

    Secondly, I have a question to ask.

    I'm having a problem with my mouse pointer, as it moves, it lags, dissapears and reappears a bit further in the direction it was headed. I'm not sure how to explain it, but it's really annoying and frustrating.

    Do you have any information or know anything about this problem and how to solve it? I've tried everything. I even re-formatted my laptop and installed Windows 7 Ultimate again with no success.

    Looking forward for your answere. Thanks in advance

    PS: Sorry if I mispelled something, English is not my mother language

  5. how about bluetooth driver?i can't found this driver for my laptop dell inspiron 1420

  6. My inspiron 1420 has been a great friend for the last 8 years. It runs Vista Home Premium and Office Pro. It was ahead of its time with 4G Ram. and duo core centrino processor. CAN this laptop be rebuilt to use Win7 32 and Office 2013? I've looked at new laptops and they seem very cheaply made!
