Upgrade your computer

Although there are many ways in which you can speed up your computer, you might let one slip out of your mind. This is the most obvious solution to low speed computers: Upgrade your computer!

When you buy it, your PC can be high-end and everything will work perfect on it. However, after less than 2 years, you will discover that some programs, games, or other applications will start working slowly. This means you need an upgrade.

The first question is what to upgrade. Let’s start with the beginning: the central processing unit (CPU). The Central Processing Unit (CPU) is responsible for interpreting and executing most of the commands from the computer's hardware and software. It is often called the "brains" of the computer. Today, Intel is the best-known manufacturer of computer CPUs. No matter what type of computer you have, however, your CPU works by executing a series of stored instructions known as a program. Most CPUs conform to the von Neumann architecture, which says that the CPU must fetch, decode, execute, and writeback the data in a fairly rapid succession. Since the CPU is one of the most important parts of a computer, it should come as no surprise that it is also the most expensive. However, you will immediately feel the power of a new central processing unit. Speed will be dramatically increased.

The second most important component you should upgrade is the RAM. Random Access Memory (RAM) is the "working memory" in a computer. Additional RAM allows a computer to work with more information at the same time which can have a dramatic effect on total system performance. So, basically, the more RAM you can get, the faster your computer will work. However, note that RAM modules work at different frequencies. RAM with higher frequency works faster. Each motherboard supports only a certain range of memory types in certain combinations so always check with your motherboard manufacturer before making a purchase.

The third thing you should upgrade is the hard disk drive. All the data (well, almost all) is read from the hard disk drive and written on it. So, the faster it goes, the faster your system will operate. These pieces of hardware come at speeds from 5400 to 15000 rpm. Low, 5400 rpm, hard disk drives are slow and obsolete. High, 15000 rpm, are extremely expensive server hard disk drives. All you need is a 7200 or 10000 rpm hard disk drive, and your computer will achieve maximum speed.

You can encounter errors when upgrading your computer due to different incompatibilities. If your mainboard is old, it might not support your upgrades. You need to buy a mainboard that clearly supports the hardware you want to install. Always check the technical documentation before you buy anything. For example, your mainboard must support the RAM’s frequency, or have a specific slot for your new CPU. AMD and Intel central processing units use different slots – AMD is on slot A, while Intel is on Socket T (also known as Socket 775 or LGA 775).
