We repair computers and we set up new ones, so we don’t care which answer wins. We just want it to be the right one for the machine in front of us. Here’s the math we run at clients’ kitchen tables.

The rule of thumb

If the repair costs more than half what a suitable replacement costs, replace. The repair itself isn’t the problem. The catch is that you’d be spending serious money on a machine whose oldest parts still have to hold up too. A $300 repair on a $500-class computer that’s already eight years old is rarely the bargain it looks like.

Below that line, repair happily. A $120 fix that buys a good machine three more years is excellent value.

Age matters less than you’d think, with one exception

A well-built computer doing light work (email, browsing, documents) can serve a decade. Don’t let anyone tell you five years is “old” for what most households do.

The exception is support cutoffs. When a machine can no longer receive security updates, it becomes unsafe for banking and email regardless of how well it runs. That’s what happened to a whole generation of PCs that couldn’t move to Windows 11: Windows 10’s end of support forced exactly this conversation in thousands of Prescott homes. An unsupported machine isn’t broken, but its clock has run out for anything sensitive.

Signs it’s time

Repairs are becoming a subscription (this is the second or third this year)
It can’t run a current, supported operating system
The battery, screen and something else all need attention at once
It struggles with the specific thing you bought it for
You’ve started avoiding using it, the quiet tell people notice last

Signs it just needs help

It was fine two months ago (sudden decline is usually fixable, or a failing drive announcing itself, and either way it’s diagnosable)
It’s slow but healthy. The spinning-drive-to-SSD upgrade makes old machines feel new for a fraction of replacement cost, and it’s the single best value in computing
The problem is clutter, not capability

If the answer is replace

Two pieces of unsolicited advice from the people who’ll set it up either way:

Buy one notch above the cheapest. The bottom-shelf machines at big-box stores are built to hit a price, and they arrive slow. The next tier up typically buys years of extra useful life for a couple hundred dollars.

Budget the migration. The new computer is the easy part; your files, passwords, email and printers moving over intact is what makes it feel like your computer by dinnertime. That’s a fixed-price service for us, and members take their discount on it.

Standing in a store aisle unsure? Call us from there. Ten minutes of “here’s how you use it” beats an hour of spec sheets, and we’d rather save you from the wrong purchase than migrate you off it later.
