10 Essential Questions to Ask Before Buying a New Computer

Buying a new computer should be exciting. You’re investing in a machine that will help you work, create, relax, browse, binge-watch, edit, game, or simply procrastinate more efficiently. Yet unless you spend your days knee‑deep in tech jargon, the process can feel like wandering into a foreign country where everyone speaks in acronyms and the shop assistant is trying to sell you antivirus software you definitely don’t need.

Walk into any electronics store and you’ll be greeted by rows of laptops, desktops, mini PCs, all‑in‑ones, convertibles, and devices that look like they belong on the bridge of the Starship Enterprise. They all have different processors, memory configurations, storage types, screen technologies, ports, and battery claims that sound suspiciously optimistic. Without the right questions, it’s easy to walk out with something outdated, underpowered, or simply not suited to your needs.

To help you avoid buyer’s remorse (and to avoid being upsold into oblivion), here are the ten questions you should always ask before buying a new computer.

1. Has your PC range got the latest generation of processors?

The processor is the brain of your computer, and like human brains, some are sharper, faster and more capable than others. The two big names you’ll see are Intel and AMD, both of which release new generations of processors regularly. These updates usually bring improvements in speed, efficiency, graphics performance and AI‑related tasks.

In recent years, a third major player has entered the Windows world: ARM‑based processors, particularly those from Qualcomm’s Snapdragon range. These chips are designed for excellent battery life, silent operation and impressive efficiency. Modern ARM laptops can run Windows smoothly, handle productivity tasks with ease, and the higher‑end models are now powerful enough for creative work and even gaming. They’re no longer the experimental oddities they once were.

The tricky part is that new processors don’t always appear in shops immediately. Retailers often continue selling older stock for months, sometimes years, after a new generation launches. A laptop that looks shiny and modern on the shelf might be hiding a processor that’s two or three generations old.

Manufacturers also love giving processors fancy names like “Ultra”, “Max”, “Turbo”, “AI‑Enhanced” or “Super‑Hyper‑Mega‑Core” (I may have made that last one up). Don’t be fooled by branding. What matters is the actual processor model number and generation.

Before buying, check the official Intel, AMD or Snapdragon websites to see what the latest generation is. If the model you’re being shown is significantly older, you’re not getting the best value for your money.

2. Can I Add More Memory?

Memory (RAM) is one of the biggest contributors to how fast and smooth your computer feels. More RAM means more apps open at once, faster switching between tasks, and fewer slowdowns when working with large files.

These days, 16GB of RAM is the sweet spot for most people. It’s ideal for everyday use, photo editing, light video editing and gaming. Professionals working with large video projects, 3D modelling or heavy multitasking will benefit from 32GB or more.

However, not all computers allow you to upgrade the RAM. Many thin and light laptops now have the memory soldered directly onto the motherboard, meaning what you buy is what you’re stuck with forever. Others still offer upgradeable RAM through one or two slots.

Ask how many RAM slots the computer has, how many are used, and whether the RAM is replaceable. On some laptops, upgrading is as simple as removing a small panel. On others, you’ll need to remove the entire bottom cover. And on a few, you’ll need the patience of a saint and a toolkit that looks like it belongs to a watchmaker.

If you want your computer to last several years, upgradeability is a major advantage.

3. How easy is it to replace or upgrade the storage drive?

Storage has changed dramatically. Traditional mechanical hard drives (HDDs) are now mostly reserved for budget desktops or external drives. Solid‑state drives (SSDs) are the standard for modern computers because they’re faster, quieter, more reliable and far better for performance.

Most laptops now use NVMe SSDs, which are tiny, fast and easy to replace—if the manufacturer hasn’t soldered them in place. Some ultra‑thin laptops use soldered storage, meaning you can’t upgrade it later. Others use proprietary SSDs that can only be replaced with the manufacturer’s own expensive parts.

A typical modern laptop should come with at least 512GB of storage. For many people, 1TB is the ideal balance between cost and space, especially if you store photos, videos or games.

Ask whether the SSD is replaceable, what type it uses, and whether there’s space for a second drive. Being able to upgrade storage later can extend the life of your computer significantly.

4. Is the screen glossy or matte?

Screens come in two main finishes: glossy and matte.

Glossy screens look fantastic in shops. Colours pop, contrast is high, and everything looks shiny and cinematic. They’re great for watching films, editing photos or playing games.

The downside is reflections. If you’re near a window, under bright lights, or sitting anywhere other than a perfectly controlled lighting environment, you may find yourself staring at your own face more than the screen. Not ideal unless you enjoy surprise self‑portraits.

Matte screens reduce reflections and glare, making them better for productivity, writing, browsing and general everyday use. They’re easier on the eyes and more practical in bright environments.

Choose glossy if you prioritise entertainment and colour vibrancy. Choose matte if you value comfort and clarity.

5. How many times can the battery be recharged?

Laptop batteries don’t last forever. Each battery has a limited number of charge cycles—one cycle being a full charge from 0% to 100%.

Many laptops offer around 500 charge cycles before the battery capacity starts to noticeably decline. Higher‑quality models can reach 1,000 to 1,500 cycles, meaning the battery can remain healthy for four to six years depending on usage.

Replacing a battery can cost anywhere from £50 to several hundred pounds, depending on the model. Some laptops have easily replaceable batteries; others require professional servicing.

If you’re buying a cheaper laptop, replacing the battery might cost more than the computer is worth. In that case, it may be more sensible to replace the entire machine when the battery eventually gives up.

Ask about battery cycle ratings, replacement costs and whether the battery is user‑replaceable.

6. What warranty and repair options are available?

Warranties can be confusing. In the UK, electronic goods are expected to last a reasonable amount of time — at least six months as a minimum. Manufacturers usually offer a 12‑month warranty as standard, sometimes longer, but it’s important to ask about this before you buy. You can technically make a claim for up to six years, but after the first six months the burden of proof shifts to you. That means you’d need to pay for an independent assessment to show the fault was present when you bought the device.

If a product develops a fault within the first 30 days, you have the right to return it to the retailer or manufacturer and request either a full refund or a brand‑new replacement. After 30 days — but within the first six months — the retailer or manufacturer can choose to repair or replace the item. They are not legally required to offer a refund unless they cannot fix the problem.

Within the first six months, the shop that sold you the device must arrange the repair, replacement, or whichever remedy is appropriate. After six months, but still within the manufacturer’s 12‑month warranty, you may be required to deal with the manufacturer directly. It’s always worth checking whether the retailer will handle the process on your behalf once the six‑month period has passed, as policies vary.

Extended warranties are often pushed quite aggressively by sales staff. They’re usually expensive and rarely worth the money, especially when you already have the right to make a claim for up to six years. Many faults that appear after the first year are minor, inexpensive to fix, or covered by consumer rights legislation anyway.

Before you buy, ask who handles repairs, how long they typically take, and what your options are if something goes wrong.

7. What ports does it have—and does it include modern USB standards?

USB 3.0 used to be the big question, but modern computers now use USB‑C, USB 3.2, USB4 and Thunderbolt ports. These ports allow faster data transfer, external displays, charging and docking.

Some ultra‑thin laptops only include USB‑C ports, meaning you’ll need adapters for older accessories. Desktops usually offer a wider range of ports, but it’s still worth checking.

Make sure the computer has the ports you need for your devices, whether that’s USB‑A, USB‑C, HDMI, SD card readers or Ethernet.

8. Can the PC be connected to a television or external monitor?

Most modern computers can connect to TVs and monitors easily, but the method varies.

HDMI is still the most common connection for TVs. Many laptops include HDMI ports, but some rely on USB‑C or Thunderbolt to output video. These ports can connect to HDMI with the right adapter.

If you plan to use your computer for presentations, gaming on a big screen, or watching films on your TV, check what video outputs it supports.

Also check whether it supports 4K output at 60Hz or higher if you have a modern TV or monitor.

9. Does it have an optical drive—and do you actually need one?

Optical drives (DVD and Blu‑ray) have gone the way of the fax machine: not quite extinct, but definitely not thriving.

Most modern laptops don’t include them because they take up space and add weight. Software, films, music and even operating systems are now downloaded rather than installed from discs.

If you still need an optical drive occasionally, you can buy an inexpensive external USB DVD or Blu‑ray drive. There’s no need to limit your laptop choices based on this feature.

10. What is the screen resolution?

Screen resolution determines how sharp and detailed your display looks. On laptops and desktops, the most common resolutions are:

• Full HD (1080p)
• Quad HD (1440p)
• 4K (2160p)

For everyday use, 1080p is perfectly fine, especially on smaller screens. On larger screens (15 inches and above), 1440p offers a noticeable improvement in sharpness without the battery drain of 4K.

4K screens look stunning but are more expensive and use more power. They’re ideal for creative professionals or anyone who wants the best possible image quality.

Gaming laptops sometimes offer high refresh rates (120Hz, 144Hz, 240Hz or more). These make motion look smoother and are great for fast‑paced games.

Choose the resolution that matches your needs, not just the biggest number on the box.

Conclusion

Buying a new computer doesn’t have to feel like decoding ancient hieroglyphics. By asking the right questions, you can cut through the marketing fluff, avoid outdated hardware, and make sure you’re getting a machine that suits your needs today and for years to come.

Whether you’re choosing a sleek laptop, a powerful desktop, or a compact mini PC, understanding processors, memory, storage, screens, ports and warranties will help you make a confident, informed decision. And if a salesperson tries to convince you that your brand‑new computer needs £80 antivirus software to survive its first week, feel free to smile politely and walk away.

Your perfect computer is out there—you just need to know what to ask.
