Computer parts and upgrades

Before replacing a computer, it is worth knowing whether one part is holding it back. Often one is, and the fix costs a fraction of a new machine.

The upgrade that changes the most

Replacing a mechanical hard drive with a solid-state drive changes how a computer feels more than any other single change. Starting up, opening programs and switching between them are all storage work, and a machine that felt tired often feels new afterwards.

If a computer is several years old and still has a mechanical drive, this is almost always the first thing to look at.

When more memory is the answer

If a machine slows down specifically when several programs or many browser tabs are open, and recovers when you close some, it is running short of memory. Adding memory addresses that directly; a faster processor does not.

Whether it can be added depends on free slots and what the board supports — worth checking before buying anything.

When an upgrade is not worth it

Sometimes the honest answer is that a machine has reached the end of sensible investment: the parts it would need are expensive relative to its remaining life, or the design does not permit them. We would rather tell you that than take payment for parts that will not help for long.

New parts carry a one-year warranty, excluding acts of God, physical damage and neglect.

Common questions

How do I know which part is the bottleneck?

The symptom usually names it. Slow to start and slow to open programs points at storage. Fine until several things are open points at memory. Struggling in games or 3D at otherwise normal speed points at graphics. If it is not obvious, a diagnosis will establish it.

Is it cheaper to upgrade or replace?

It depends on what is holding the machine back and how much life is left in the rest of it. A single drive or memory upgrade to an otherwise sound computer is usually far cheaper than replacement. A machine needing several parts at once rarely is.
