Why Is My Laptop
So Slow?

Seven things to check before you spend money on a new one.

Before You Buy a New Laptop, Try This

A slow laptop is one of the most common complaints we hear from home users — and one of the most common reasons people end up buying a new machine they didn't actually need. In our experience, most "slow" laptops can be brought back to life with a few free or low-cost fixes. Here's what to check, in order, before you spend any money.

1. Check What's Launching at Startup

If your laptop takes ages to become usable after switching on, the culprit is usually too many programs launching automatically. On Windows, open Task Manager (Ctrl + Shift + Esc) and click the Startup apps tab. Anything you don't recognise or rarely use can usually be disabled here — it won't uninstall the program, just stop it loading automatically.

2. See How Full Your Storage Drive Is

A storage drive that's more than about 90% full can slow your whole system down, especially on older laptops. Open File Explorer → This PC and check the free space on your main drive. If it's nearly full, clearing out old downloads, duplicate photos and unused programs is a quick win.

3. Run a Full Virus & Malware Scan

Malware running quietly in the background is a common cause of a laptop that's slow all the time, not just at startup. Run a full scan with a reputable antivirus tool. If you don't have one installed, that's worth fixing on its own — see our cyber security page for advice.

4. Check for Pending Windows Updates

An update that's stuck "downloading" in the background can eat your bandwidth and processing power for days. Go to Settings → Windows Update and check for and install any pending updates, then restart.

5. Count Your Open Browser Tabs

Each open browser tab uses memory, even ones you're not actively looking at. If you regularly have 20+ tabs open across several windows, that alone can make a laptop with 8GB of RAM feel sluggish. Try closing tabs you don't need, or use a tab-suspending extension.

6. Check If You Still Have a Hard Disk Drive (HDD)

If your laptop is more than about 5 years old, it may still have a traditional spinning hard drive rather than a solid-state drive (SSD). This is, by far, the single biggest cause of a slow-feeling laptop that we see — and an SSD upgrade is usually the most cost-effective fix available, often making an old laptop feel genuinely new again.

7. Check the Battery & Power Settings

Some laptops automatically throttle performance when running in a battery-saving power mode. Check Settings → Power & battery and make sure you're not stuck in a power-saving mode while plugged in.

Still Slow After Trying These?

If you've worked through this list and your laptop is still struggling, it's worth getting a second opinion before spending money on a replacement. We can connect remotely, diagnose exactly what's slowing your machine down, and tell you honestly whether a quick fix, an upgrade, or a new device is the right call — no pressure either way.

Frequently Asked Questions

Will more RAM make my laptop faster?

Often, yes — especially if you regularly have many browser tabs or programs open at once. But if your laptop still has a traditional hard drive instead of an SSD, upgrading storage usually makes a bigger difference than adding RAM.

How do I know if my laptop has a virus slowing it down?

Signs include the fan running constantly even when idle, programs you didn't install, browser pop-ups, or your antivirus showing warnings. A full scan with a reputable antivirus tool is the best way to check.

Is it worth repairing an old slow laptop or buying a new one?

If the laptop is under about 5 years old and still has a traditional hard drive, an SSD upgrade often makes it feel brand new for a fraction of the cost of replacement. Beyond that age, or if the hardware itself is failing, replacement is usually more cost-effective.
