How to upgrade computer hardware

Computers do not last forever. Although the system itself may continue to trundle along happily doing the tasks it has always done, time and technology can render it slow and obsolete. New software will refuse to run on it or run slowly. New hardware may be incompatible with older parts. Eventually there comes a time when you have to look into how to upgrade computer hardware just to keep computing.

Effects

• When performed correctly, the effect of upgrading computer hardware is twofold. First, it improves performance, either through increased memory capacity, faster processor speeds or simply decreased search and load times. Second, it extends the viable operational life of the computer as a whole by allowing the system to continue running the latest software. A good upgrade means replacing the parts that are holding the system back while keeping those parts that are still working effectively.

Types

• There are numerous types of computer hardware upgrade. Installing a faster processor improves the main running speed of your system. Adding more memory lets you run larger programs or current programs without constant hard drive access for virtual memory. A larger hard drive allows you to store more information, while a new graphics card or monitor lets you view images in greater detail.

Identification

• Identifying the part to replace can be difficult. If the system is running slowly, it could be that the processor is too slow for the tasks you need to undertake. This could also be due to limited memory, and you should check whether the hard drive is being constantly accessed, an indication of excessive virtual memory use. Graphical glitches can indicate a need to upgrade the graphics card.

Size

• When considering how to upgrade computer hardware, the size of the upgrade will depend on your current system, what you will use the upgraded system for and your budget. It is pointless buying 4 gigabytes of RAM if you know you can achieve everything you want to with 1 gigabyte extra. Similarly, if the latest quad-core processor is too expensive, ask yourself whether a smaller chip will do just as well.

Considerations

• When money is no object, the capabilities of your current system will determine the maximum size of your potential upgrades. Older motherboards are not always compatible with the latest technology, so check what you can fit to your system before you buy it. This has a knock-on effect as replacing one component may render another component incompatible. Check compatibilities before handing over any money, or your upgrade could be very expensive.
