If your computer is slow and you've already ruled out virus infections and too many unnecessary programs, it may be time to get new computer parts for your computer. A completely new computer may be in order, but if you'd like to save some money and build your own, here are some technical considerations for getting the right parts for the right purposes.

What Is Your Computer For?

One of the biggest mistakes that computer builders make is trying to build a system that 'does it all'. When a new generation of parts are at the forefront, you may be able to sit at the top of the computer industry for a few months at best.

After a while, specialized manufacturers and different industries will find better ways to optimize for certain parts, and your generalized power computer may be reduced to a heat-generating paper weight.

Instead, know what your main focus will be and build around that purpose. There's nothing wrong with wanting to have multiple purposes for your computer, but avoid adding specialized parts that you have no expertise in or daily purpose with. The constant heat and wasted resources will only lead to a faster computer failure.

Which Parts Are Common In All Computer Designs?

Processors are essentially the 'brains' of the computer, responsible for everything from moving the mouse to opening up document software to the inner workings of your computer's operating system. Modern processors have multiple cores, which are basically multiple processors inside one processing unit. These processors help each other with load balancing, meaning that each core shares the burden with other cores.

The memory helps the processor by acting as a quick storage for information. Instead of searching a large hard drive for random information, the most commonly used files are kept in memory for quick access.

Hard drives are for storing information. Whether you're saving videos, music, games or documents, you'll need a hard drive to save the information you need without going to search the Internet for the same information every time you need it. 

Monitors are required for using most computers, although devices such as laptops, tablet computers and smartphones have built-in screens. Only one monitor is needed, but productive people have found great benefits from having at least two monitors to look at other information while keeping their main task in view.

General Business Computers

Although general business matters are important, they do not necessarily require high amounts of power. No matter how important a financial document is or how vital a report may be, basic documents simply don't take up a lot of processing power.

Instead, design general computers for basic multitasking. You'll need a processor to keep up with modern office management software and Internet browsing, as well as enough memory to run programs efficiently.

Hard drive space is not vital in the current market. Hard drives measuring in terabytes are becoming increasingly affordable, and are far more than what most business professionals need. That said, buying a hard drive at a smaller size is not necessarily cost effective. Try for at least a 1 terabyte hard drive.

Video Intensive Computers

If you plan on playing games, editing art or creating intense animation products, you'll need a graphics card. A graphics card is basically a secondary board that holds a processor and memory just for graphics.

Instead of forcing the main processor and memory to handle the entire computer--including high performance games and graphics editing software--the graphics card takes over to provide not only extra resources, but instructions for efficiently displaying images and performing graphics calculations that a standard processor isn't designed to do.

For any game or editing software brand, look for the recommended specifications and try to match them. There are also minimum specifications, but these values may result in poor performance. If you need help pairing the specifications to a specific part, contact a computer store representative, such as those at McMurray Computer Experts.
