Okay, let’s be real for a second. You press the power button, you go make a coffee, you come back… and Windows is still loading. Sound familiar ? Honestly, I’ve been there too, and it’s one of the most frustrating things ever. The good news ? In most cases, your PC isn’t dead. It’s just clogged up, overloaded, or badly configured. And nine times out of ten, you can fix it yourself in an afternoon.

Before you start browsing for a brand new laptop (and spending £600 you don’t really want to spend), give these tricks a shot. I’ve used them on dozens of machines, including my mum’s old Dell that everyone said was “good for the bin”. Spoiler : it’s still running today. If after trying everything below your computer is still dragging, it might genuinely be a hardware issue, and in that case a real technician like the ones at https://informatique-depannage.fr can take a proper look. But seriously, try these first.

1. Clean up your startup programs (the silent killer)

This one. This is the number one reason your PC takes forever to boot. Every app you install thinks it’s important enough to launch with Windows. Spotify, Skype, Adobe, OneDrive, Discord, your printer software… they all queue up at startup and eat your RAM before you’ve even opened a browser.

Press Ctrl + Shift + Esc, click on the “Startup” tab, and disable everything you don’t absolutely need. Don’t worry, you won’t break anything. The apps will still work when you click them manually. Honestly, the difference after a reboot is sometimes night and day.

2. Free up disk space (your SSD is suffocating)

An almost full hard drive equals a slow computer. It’s that simple. Windows needs breathing room to manage its temporary files, updates, and virtual memory. If you’re running below 15% free space, you’re in the danger zone.

Open Settings &gt ; System &gt ; Storage and let Windows show you what’s eating your disk. Photos ? Old downloads ? Games you haven’t touched in two years ? Out they go. You can also use the built-in Disk Cleanup tool, which is old-school but surprisingly effective.

3. Uninstall the junk you forgot about

Be honest. When was the last time you opened that PDF reader you installed in 2021? Or that “free” video converter that came bundled with something else ?

Go to Settings &gt ; Apps &gt ; Installed apps, sort by name, and delete everything you don’t recognise or don’t use. Be careful with anything that says “Microsoft” or your laptop brand (HP, Dell, Lenovo drivers), but the rest ? Bin it. You’d be surprised how much your PC thanks you.

4. Run a proper malware scan

Sometimes your computer isn’t slow. It’s working really hard… for someone else. Cryptominers, adware, browser hijackers – these things love hiding in the background and eating your CPU.

Windows Defender is decent, but I’d also recommend running Malwarebytes Free once. Just once. If it finds nothing, great. If it finds 47 threats, well, you’ve got your answer. Did you know browser extensions can also be a huge source of slowdown ? Check yours and remove anything sketchy.

5. Switch from HDD to SSD (the real game changer)

If your computer still has a mechanical hard drive (HDD), I’m going to be honest with you : nothing else will help as much as switching to an SSD. Nothing. A 500GB SSD costs around £40 these days, and the difference is genuinely insane. Boot time drops from 3 minutes to 15 seconds. Apps open instantly.

Is it worth doing yourself ? If you’re comfortable with a screwdriver and a YouTube tutorial, absolutely. If not, any local repair shop can do it in under an hour. This is the single best upgrade you can make on an old laptop.

6. Add more RAM if you can

Got 4GB of RAM? That’s the problem. Modern Windows wants 8GB minimum, ideally 16GB if you’re a Chrome addict like me (40 tabs, no shame). Check if your laptop has a free RAM slot – many do – and add a stick. It’s cheap and the difference is immediate.

Quick tip : open Task Manager and look at the “Memory” tab while you work normally. If it’s hitting 90%+ regularly, that’s your bottleneck right there.

7. Update Windows AND your drivers

Yeah, I know. Updates are annoying. But outdated graphics drivers or BIOS can absolutely tank your performance. Go to Settings &gt ; Windows Update, install everything, then visit your laptop manufacturer’s website (HP, Asus, Dell, whatever) and download the latest drivers from there.

Don’t bother with those “driver updater” tools that pop up everywhere. Most of them are scams or bloatware. Stick to official sources.

8. Clean the dust out (yes, physically)

Your PC is hot. Like, really hot. And when it overheats, it slows itself down on purpose to avoid frying. It’s called thermal throttling and it’s super common on laptops more than 2 years old.

Grab a can of compressed air, shut down your computer, and blow out the vents. The amount of dust that comes out will horrify you. For desktops, open the case and clean the fans properly. Want to go further ? Replacing the thermal paste on the CPU can drop temps by 10-15°C, but that’s a bit more advanced.

9. Disable visual effects and animations

All those smooth Windows animations ? They look great on a new machine. On an old one, they’re just slowing you down for no reason.

Type “performance” in the Start menu, open “Adjust the appearance and performance of Windows”, and select “Adjust for best performance”. It’ll look a bit retro, sure, but your PC will feel snappier instantly. Worth it ? I think so.

10. Consider a clean Windows reinstall (the nuclear option)

Last resort, but seriously effective. After 3-4 years of installs, uninstalls, updates and registry mess, Windows just gets… tired. A clean reinstall is like giving your PC a brand new life.

Back up your important files first (don’t skip this !), grab the official Windows installation tool from Microsoft’s website, and follow the steps. It takes about an hour. When you boot back up, you’ll feel like you bought a new computer. Promise.

So, ready to give your PC a second chance ?

Honestly, between cleaning up startup programs, swapping in an SSD, and removing dust, you can easily double the perceived speed of an old laptop. Most “slow computers” aren’t actually broken – they’re just neglected.

Try these steps in order, see what works for you, and only consider replacing your machine if hardware really is the problem (CPU too old, motherboard issues, etc.). Your wallet will thank you, and so will the planet. What’s the first thing you’re going to try ?
