Hands-on PC builds, upgrades and buying advice for the UK
A PC that reboots under load or shuts down without warning often gets blamed on the power supply. Before you box it up for an RMA, spend £12 on a plug-in socket tester and a energy monitor — in plenty of UK homes, the wall is the more interesting suspect.
Most 12V-2x6 problems aren't caused by a badly made cable — they're caused by a side panel pressing it into a hard bend a centimetre from the plug. Here's the clearance and bend-radius routine UK builders should run before a new graphics card goes into service.
One monitor, one keyboard, one mouse — and two machines fighting over them. Here's how to pick a KVM switch that actually behaves in 2026, where the £20 model is genuinely enough, and the point at which you should stop being clever and buy a dock instead.
Modular PSU cables look like generic spares, but the pins behind the plastic can carry different voltages. Here’s how UK upgraders can audit a second-hand PSU, label its leads and test a build before the first full power-on.
A second M.2 slot looks like free storage space, but on many mid-range boards it quietly disables SATA ports, halves a slot’s bandwidth or borrows lanes from your graphics card. Here’s the manual-and-BIOS check UK upgraders should run before spending £100 on an NVMe drive.
A desktop that loses the time, forgets its boot order or greets you with a BIOS prompt is not automatically a dead motherboard. Before you price up a replacement, work through the humble CR2032 coin cell and the handful of checks that separate a £3 fix from a much bigger repair.
A USB-C socket on a case front panel can still be a 480Mbps port in disguise. Before you pay a £20 premium for a case with USB-C, check the cable, the header and the actual speed rating — here’s the practical UK buyer’s checklist.
AM4 still has one sensible upgrade left in it, but only if your motherboard, VRM and cooler can take it. Here’s the practical UK check for 2026 — and the point where spending £180 on an old platform stops making sense.
Spare bedrooms and loft conversions make handy offices until winter turns them into condensation traps. Here is what moisture does to a running PC, how to spot the early warning signs, and why a £25 hygrometer plus a smarter heating routine can save you a repair bill.
Every few months another wave of ex-corporate micro desktops lands on UK refurb shelves at pocket-money prices. Here's how to pick a good one, dodge the three traps that catch most buyers, and spend £120–£200 on a desktop that sits silently under a monitor and sips electricity.
A cheap USB Wi-Fi dongle can make a perfectly good broadband line feel broken in an old UK terrace. Here’s why an £18 PCIe card often wins, what to check before buying, and when you should stop fiddling and run a cable instead.
That old SATA SSD is not e-waste — put it in a decent USB enclosure and you have the core of a proper home-office backup for about £45. Here is how to pick the enclosure, test it honestly, schedule a weekly image and prove the restore works before you need it.
Black Friday 2026 lands on 27 November, but most PC component ‘deals’ are just last month’s price with a red badge. Here are the five parts worth setting an alarm for, three banners to ignore, and a quick UK checklist before you pay.
Cheap 1TB NVMe drives look brilliant in a benchmark and in a UK retail listing, but the experience can fall apart during a Windows feature update, a game install or a large office file copy. Here’s what the spec sheet glosses over, and how to buy a drive that stays sensible once the cache runs dry.
A desktop that has slowly turned into a leaf blower is usually asking for maintenance, not a replacement. Here is a practical £40 plan for UK desks: clean the dust traps, swap the worst fans, fit a budget cooler and set a sane fan curve — then prove the difference with a simple before-and-after test.
Wi-Fi has become the default for every desktop, even the ones that never move. For a small UK office, a second Ethernet port — built in or added with a £25 PCIe card — can simplify NAS backups, printer isolation, failover and troubleshooting. But it is not automatic; here is when it earns its keep and when one cable and a cheap switch are enough.
A cheap CPU upgrade can stall at the first POST if the board’s firmware is older than the chip. Here’s how UK builders can check support, pick the right BIOS, and use USB Flashback without turning a routine swap into a dead motherboard.
Leaving a desktop on all day and night is not automatically ruinous, but it is rarely free. Measure the wall socket, do the unit-rate maths, and decide whether sleep, wake-on-LAN, or a smaller machine makes sense.
A cheap power supply is still the fastest way to turn a tidy budget build into an expensive lesson. Here is what £60–£80 really buys from UK retailers in 2026, which specs matter, and when to stop bargain-hunting.
A mini-PC, NAS and router can ride out a short outage on a sensible £100 UPS — if you size it properly. Here is the UK checklist for VA, watts, sine wave output and testing without wasting money.
