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

Why is my laptop so slow?

Common causes include too many startup programs, a nearly full storage drive, malware running in the background, pending Windows updates, too many browser tabs open, a traditional hard drive instead of an SSD, or a power-saving mode throttling performance.

Will more RAM speed up my laptop?

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

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

If the laptop is under 5-6 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.

How do I check if my laptop has an SSD or hard drive?

Open Device Manager in Windows, expand Disk Drives, and look at the listed drive name. Most SSDs include 'SSD' or 'NVMe' in the name. Alternatively, open Task Manager, click the Performance tab and select Disk — it will show the drive type.

Can a slow laptop be fixed remotely?

Yes — software causes of slowness such as startup programs, malware, full drives, pending updates and power settings can all be diagnosed and fixed remotely. Hardware upgrades like adding an SSD need hands-on work.

How do I stop my laptop being slow at startup?

Open Task Manager (Ctrl+Shift+Esc), click the Startup apps tab, and disable any programs you don't need loading automatically. This is the single most common fix for a slow startup.
