The Compaq D5S Evo desktop line of computers gained popularity because of its small form factor and powerful Pentium 4 processor. Small form factor computers take up less space than regular-sized desktop computers while performing the same functions. The Pentium 4 processors in these machines mean you perform many computing tasks. These processors also allow an easy upgrade.

Since the merger of Compaq and Hewlett-Packard (HP), HP maintains support for these machines. Some vendors list the D5S Evo desktop among their HP products. Benefits of buying a Compaq Evo D5S refurbished computer include:

1. You will save money buying a refurbished Evo D5S instead of a new computer;

2. You help the environment by keeping older computers from ending up in a landfill;

3. And you receive a computer restored to like-new condition.

Action Steps
The best contacts and resources to help you get it done

Buy Compaq Evo D5S desktop computers online

Since Compaq no longer makes the Evo D5S model, you will have to choose a refurbished Compaq Evo D5S to buy or choose a newer model. Vendors service and repair refurbished computers to restore them to the manufacturer's quality standards. They usually come with a limited warranty.

I recommend: Buy refurbished Compaq desktop models including the Compaq D5S that the staff have stringently tested and cleaned at PreLoved Computers. Find refurbished computers at low prices at PCLiquidations.com, where the company will buy your old computer equipment.

Upgrade your Compaq D5S memory

Limited memory, or RAM, is one of the biggest reasons people outgrow their computers. Add more memory so you can run the latest software. Be careful to determine the maximum amount of RAM for your computer's motherboard before you buy.

I recommend: MemoryTen can scan your computer to determine the correct memory, or you can shop by computer make and model to buy memory for your Compaq D5S. Use the online tools to find the right memory for your Compaq desktop at Crucial.com, a division of Micron Technology, which sells quality memory backed by good customer support and product warranties.

Download updated Evo D5S drivers

Drivers are software files that tell a computer how to run or interface with a specific piece of hardware. Whether you install new hardware or your hard drive crashes, you may need to replace drivers. You can download updated drivers for free.

I recommend: Find a Compaq Evo D5S driver and other support options for your Compaq Evo desktop at Hewlett-Packard. Scan your system to identify drives that need updating or search the site for the drivers you need at Driver Guide.
