A customer from the Lanark Road end of Balerno brought in a quietly dying desktop last month and asked the question we hear most often from this side of the city: “Is it worth saving, or is it time to let it go?” The tower was a mid-range office machine from 2014, cleaned twice over the years, with a mechanical hard drive still doing all the work. It booted, in a sense. It took four minutes to reach the desktop and another two before Chrome would open. Our honest answer that morning was not the one most online guides give, and it is the one this piece sets out.
There is almost always a repair or an upgrade that will make an old PC usable again for a while. The real question is whether the money and time make sense against what the machine will still be in a year. On the bench we check four things before we say “retire” out loud: the drive’s health, the Windows 11 hardware floor, the state of the motherboard, and what you actually use the PC for. If a small hardware upgrade like an SSD lifts it over all four, we fit it. If it only clears one, the honest advice is usually different.
The Drive Is Usually the First Clue
Any PC that still has a spinning hard drive as its C: drive feels slow regardless of its age, and most machines that come through the shop have one. Before anything else we read the drive’s SMART data to see what it is really doing. A healthy mechanical drive will show a reallocated-sectors count of zero and a pending-sectors count of zero. Once either of those is non-zero and climbing, the drive is actively failing, and no amount of software care fixes it. On the Balerno tower both counters were in double digits and the pending count had risen between the morning we read it and the following day.
A failing drive is not, on its own, a reason to retire the PC. If the rest of the machine is sound an SSD and a Windows reinstall gives it years back, and our guide to when a Windows reinstall is actually the right call covers the thinking there. The reason we start with the drive is that any customer data on it has to be treated as living on borrowed time: before anything else, we take a copy. If the drive is already past the point where a copy will complete, that is a data recovery job, not an upgrade one.
The Windows 11 Hardware Floor
This is the quiet reason a lot of perfectly usable PCs now sit awkwardly on the shelf. Windows 11 draws a hard line at roughly 8th-generation Intel Core processors and AMD Ryzen 2000-series or newer, with a TPM 2.0 chip either on the motherboard or built into the CPU. Anything older is not supported, and the workarounds that let it install anyway cut you off from feature updates and often from security ones too. If your tower has an Intel Core i5-6500, i7-4790, Ryzen 1600 or anything with four or fewer threads, you are below the floor. Nothing you can fit into that machine will get it over.
Windows 10 reached end of support in October 2025, and the Extended Security Updates programme that followed is a stopgap, not a plan. Our write-up on Windows 10 end of support and the follow-up for a Marchmont office running on borrowed time explain what ESU does and does not cover. For a home PC that is used mostly for email, banking and photos, running without security updates is a risk that grows every month. That is where retiring the machine starts to look sensible even when it still turns on cleanly.
What the Motherboard Tells Us
With the side off the case we look for two things: bulging or leaking capacitors near the CPU socket and around the power circuitry, and dust compacted into the heatsinks. The first is a hardware failure that puts an end to any sensible repair; we have seen it most on Dell OptiPlex and HP SFF office PCs that spent ten years under a desk. The second is cosmetic and is one of the easier wins we get on the bench, as our overheating fix work in Balerno covers.
We also look at what the motherboard can accept. A machine with only SATA storage, DDR3 memory and USB 2.0 on the back is giving away speed in every direction, and the ceiling on what an SSD and more RAM can do is low. A board with a free NVMe slot, DDR4 and USB 3 is a different conversation. On a desktop with a decent motherboard it is often more sensible to reuse the case, drive and graphics card into a new build than to try to rebuild round an old chipset, and the decision between upgrading and starting again is one we walk through with every customer who asks.
Laptops Fail Differently
Everything above applies to laptops too, with two extra signals that often mean retirement. The first is a cracked hinge mount: once the plastic or thin casting around the hinge has sheared, the screen is on borrowed time and the repair is often more than the laptop is worth. The second is a swelling battery, which pushes up on the trackpad or lifts the keyboard; it is a safety issue first and foremost. We cover both as part of our laptop repair work, and if the chassis itself is sound we will quote honestly on whether the fix is worth it.
The hardest laptop case is the thin ultrabook with soldered RAM and soldered storage. Even when the screen, battery and keyboard are all perfect, you cannot add memory or fit a bigger drive, and the Windows 11 floor still applies. For those machines we tend to recommend keeping them for a specific low-stakes job (a travel laptop, a children’s homework machine) rather than paying for an upgrade that will not land anywhere useful.
What to Rescue Before You Let the PC Go
Once the decision is made, there is a short list of things we help customers pull off before the machine leaves. Documents, photos and desktop files are the obvious ones. Less obvious are the browser bookmarks and saved passwords (export them from the browser rather than relying on the account alone), the Outlook data file if it is used offline, licence keys for any paid software, any BitLocker recovery key for the drive, and the Microsoft account that owned the PC. Our note on finding a BitLocker recovery key covers the last of those. On a desktop we usually keep the Windows product key visible until the drive is wiped, in case we need to reactivate elsewhere.
Wiping the Drive Properly
This is the step people miss. Deleting the files and emptying the Recycle Bin leaves the data intact; a quick format does little more. On a mechanical hard drive we run a full overwrite that writes zeros across the whole surface and verifies it. On an SSD we issue the manufacturer’s secure erase command, which clears the mapping table and tells the controller to start again from blank. Either way the drive leaves the shop with no readable data on it, and we document which drive was wiped in which machine so there is a paper trail. If you prefer, we can also physically destroy the platter or chip in front of you before the carcass goes for recycling.
How We Recycle It in Edinburgh
From Balerno, Currie, Juniper Green and Sighthill-Wester-Hailes, the easiest option is usually to bring the PC in with us on your next pass down Lanark Road, or to arrange a collection on a Saturday run. Working parts come out first and go into stock for repairs: good power supplies, memory, drives that are not too old and clean fans all find homes. The remainder goes through our IT recycling and e-waste disposal service, which routes WEEE waste through a licensed carrier rather than landfill. Edinburgh’s own household waste recycling centres (Sighthill, Seafield and Craigmillar) also accept small electronics at no charge if you would rather drop it off yourself.
And When a New PC Is the Right Answer
If the old machine really is done and the use case is modest, a modern mini PC or a sensible desktop will outlive it by a decade on power alone. We quote on custom PC builds that match what the machine will actually be used for, not benchmark-ticket builds, and we try to carry parts across where it is honest to do so. If a full install from the SD card up is new ground, our Windows installation service handles it with your files moved across and your usual software set up as it was. If none of this quite matches your situation, book a bench check and bring the old PC in; we are a short run from Balerno along the A70 and we are happy to tell you honestly which side of the line your machine falls on.
