The laptop has become very slow - what should I do? Complete Guide 2026

Has your laptop suddenly turned into a snail and simple tasks take forever? Don’t rush to run to a service center or buy a new device. In 80% of cases, slow operation can be fixed on your own - often the problem lies in a clogged system, outdated drivers or unoptimized settings. Even 5 year old laptops on Intel Core i5 or AMD Ryzen 5 capable of working quickly if they are properly “put in order.”

In this article we will look at exact steps to diagnose and fix brakes, starting with the simplest actions (cleaning up garbage) and ending with radical measures (reinstalling Windows or upgrading hardware). You will learn how to determine the bottleneck of your laptop - be it overloaded processor, lack of RAM or a "dying" hard drive. And also - which programs really help, and which only aggravate the problem.

1. Diagnostics: why is the laptop slow?

Before treatment, a diagnosis must be made. Slow performance can be caused by a dozen reasons, but the most common culprits are:

• 🔍 System load - background processes, viruses, startup.
• 💾 Drive problems — fragmented HDD or “dying” SSD.
• 🧠 Lack of RAM - especially when working with a browser (chrome “eats” up to 4 GB of RAM on 10 tabs!).
• 🔥 Overheating — dust in the cooler or dried thermal paste causes the processor to “thrott” (reset frequencies).
• 🖥️ Outdated software — drivers, BIOS, Windows version.

How to quickly check? Open Task Manager (Ctrl+Shift+Esc) and look at the tabs:

• Processes — what programs load the CPU or RAM.
• Performance - loading disk, memory, network.

If in Task Manager the disk is loaded at 100% for no apparent reason - this is a sure sign of problems with the HDD or SSD. And if the RAM is constantly at 90%+, it’s time to think about an upgrade or optimization.

⚠️ Attention: If the laptop not only slows down, but turns off spontaneously or reboots, the problem may be power supply or CPU overheating. In this case, it is better to start diagnostics by checking temperatures (program AIDA64 or HWMonitor).

2. System cleaning: remove junk and unnecessary programs

The first thing to do is free up disk space and remove programs that load the system. Even if you have a 500 GB SSD, a full drive will slow down.

Remove unnecessary programs through "Settings → Applications"

Empty the Trash and Downloads folder

Perform Disk Cleanup using the Windows utility (or CCleaner)

Disable programs from startup

Delete temporary files (%temp% And Temp)

-->

How to clear startup:

1. Click Ctrl+Shift+Esc → tab Autoload.
2. Sort by Column Impact on launch.
3. Disable everything unnecessary (for example, Steam, Epic Games, Skype - they can be launched manually).

For deep cleaning, use the built-in Windows utility:

1. Open This computer → right click on the disk C: → Properties → Disk Cleanup.
2. Check the boxes Temporary files, Cart, Update log files.
3. Click Clean system files (Administrator rights required).

⚠️ Attention: Don't use "optimizers" like Advanced SystemCare or Ashampoo WinOptimizer - they often delete necessary files and create more problems than they solve. For cleaning, the built-in Windows tools or a proven CCleaner (but only in manual mode!).

3. Optimizing Windows: disabling “heavy” functions

Windows 10 and 11 include many features by default that weak laptops slow down. Here's what you can safely disable:

Function	How to disable	Effect
Visual effects (window animation)	Settings → Accessibility → Transparency effects	Speed up the interface by 10-15%
Search indexing	Services → Windows Search → Stop	Reducing disk load
Background applications	Settings → Privacy → Background apps	Saving RAM and CPU
Driver updates via Windows Update	Settings → Update & Security → Advanced Settings → Driver Updates	Avoiding driver conflicts

Another hidden “brake” - Superfetch service (SysMain). It is designed to speed up the launch of programs, but on the HDD it often works exactly the opposite. To disable:

1. Click Win + R, enter services.msc.
2. Find a service SysMain.
3. Right click → Properties → Startup type: Disabled.

4. Check for viruses and malware

Viruses and mining bots are a common cause inexplicable brakes, especially if the laptop started to malfunction after visiting dubious sites or installing pirated software. Symptoms of infection:

• 🛑 The laptop slows down even on the desktop.
• 🔥 The cooler constantly works at maximum.
• 📈 Unexpected spikes in CPU load in Task Manager.
• 🔌 Fast battery drain (cryptocurrency mining loads the processor).

How to check:

1. Download Kaspersky Virus Removal Tool or Dr.Web CureIt! (these are free utilities that do not require installation).
2. Run a full scan (may take 1-2 hours).
3. Remove any threats found and reboot your laptop.

If the antivirus does not find anything, but suspicions remain, check the list of processes in Task Manager. Please note:

• Unknown processes with high CPU load (for example, svchost.exe, but not from Microsoft).
• Suspicious names like miner.exe, update.exe in non-system folders.

How to remove a miner if the antivirus does not see it?

If in Task Manager a process with a high load is visible, but the antivirus does not delete it:

1. Note the process name and its location (Command Line column).

2. Boot into Safe Mode (When starting the laptop, hold Shift + F8).

3. Delete the file manually via Explorer or command line (del "path_to_file").

4. Check the folder Autoload (C:\Users\Your_name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup) for the presence of suspicious labels.

5. Hardware upgrade: when you can’t do without it

If all software methods have been tried, but the laptop still slows down, it’s time to think about upgrade of components. Here's what really gives you a performance boost:

Accessories	Effect	Cost (2026)	Difficulty of replacement
Replacing HDD with SSD	Windows boot speed up 3-5 times, programs launch instantly	from 2,500 ₽ (256 GB)	⭐ (simple)
Adding RAM (from 4 GB to 8-16 GB)	Elimination of freezes in the browser and games	from 2,000 ₽ (8 GB DDR4)	⭐⭐ (you need to choose a compatible bar)
Replacing thermal paste	Reduce temperature by 10-20°C, stop throttling	from 300 ₽ (paste) + work	⭐⭐⭐ (disassembly required)
Cleaning from dust	Improve cooling, prevent overheating	Free or 500-1000 ₽ (in service)	⭐⭐ (you need a screwdriver and a can of air)

The most effective upgrade for 90% of laptops is replacing HDD with SSD. Even budget Kingston A400 or Crucial BX500 will turn the “snail” into a nimble device. The main thing is to check whether your laptop supports SATA III (speed up to 6 Gb/s).

If you decide to add RAM:

• 🔍 Find out the maximum amount of RAM for your model (manufacturer’s website or utility CPU-Z).
• 🔄 Buy a bar with the same frequency as the one installed (for example, if you have DDR4-2400, don't take it DDR4-3200).
• 🛠️ Install it in a free slot (if the laptop supports dual-channel mode, performance will increase by 10-15%).

⚠️ Attention: Some laptops (eg. Apple MacBook, Dell XPS 13 or HP Spectre) RAM soldered to the motherboard - upgrade is not possible. Check this before buying RAM!

6. Radical measures: reinstalling Windows and alternative operating systems

If the laptop slows down even after all the manipulations, there are two options left:

1. Reinstalling Windows — a clean system without “junk” works much faster.
2. Installing a lightweight OS - for example, Linux Mint or Windows 10 LTSC (no extra services).

How to reinstall Windows correctly:

Download the official ISO from the Microsoft website (link)

Create a bootable USB flash drive (Rufus or Media Creation Tool)

Save important files to an external drive or cloud

Write down the product key (if Windows was purchased)

-->

After reinstallation:

• 🔧 Install drivers manually from the laptop manufacturer's website (don't trust Windows Update!).
• 🛡️ Install antivirus (Kaspersky Free or Bitdefender).
• ⚡ Disable unnecessary services (see section 3).

If you're ready to experiment, give it a try. Linux Mint with the environment Xfce or Cinnamon. This OS:

• 🐧 Works faster than Windows on weak hardware (from 2 GB RAM and 20 GB disk space).
• 🔒 Does not require antivirus (there are almost no viruses for Linux).
• 🆓 Completely free (including office programs and editors).

7. Prevention: how to prevent brakes in the future

To prevent your laptop from slowing down again, follow these simple rules:

• 🧹 Once a month, clean your disk from garbage (built-in utility or CCleaner).
• 🔄 Check for viruses once every six months (even if antivirus is installed).
• 📥 Do not install programs from dubious sites (especially “cracks” and repacks).
• 🔋 Monitor the temperature - clean your laptop from dust 1-2 times a year.
• 🔄 Update drivers regularly (but not through Windows Update, but from the manufacturer’s website!).

For automatic control use:

• Process Lasso — limits the load of background processes.
• TreeSize — shows which folders take up the most space.
• Core Temp — monitors the processor temperature.

And most importantly: don't overload your laptop. If you have 4 GB of RAM, do not open 30 tabs in Chrome at the same time. If the processor is weak (Intel Celeron or AMD Athlon), do not run modern games. A laptop is a tool, and it requires careful handling!

FAQ: Frequently asked questions about laptop brakes

❓ The laptop slows down only when connected to the Internet. What's the matter?

Most likely the problem is:

• 🔄 Background updates (Windows, drivers, programs).
• 🛡️ Viruses or miners, which are activated when you go online.
• 📡 Poor Wi-Fi connection (constant reconnections load the processor).

Check Task Manager for processes with high network traffic. Also disable automatic software updates (for example, in Steam or Epic Games).

❓ After updating Windows, the laptop began to slow down. What to do?

Windows updates are often more trouble than they're worth. Try:

1. Roll back to the previous version: Settings → Update & Security → Recovery → Go back to a previous version of Windows (available for 10 days after update).
2. If a rollback is not possible, uninstall the latest update: Settings → Update & security → View update history → Uninstall updates.
3. Disable automatic driver installation via Windows Update (see section 3).

If the brakes started after a major update (for example, switching from Windows 10 to 11), the best solution is clean system installation.

❓ The laptop slows down in games, although everything was fine before. What is the reason?

Reasons for FPS drop in games:

• 🔥 Overheating - Clean your laptop from dust and change thermal paste.
• 🖥️ Outdated video card drivers - update them from the website NVIDIA or AMD.
• 🎮 Background processes - close Discord, browser, Steam before the game.
• 💾 Low disk space — games require free cache space.
• 🔄 Game update — new patches may be more demanding.

Check GPU temperature with utility MSI Afterburner. If it is above 85°C, it’s time to clean the cooling system.

❓ Is it possible to speed up a laptop without replacing hardware?

Yes! In most cases, software methods help:

• 🧹 Cleaning the system of garbage and unnecessary programs.
• ⚡ Windows optimization (disabling visual effects, background services).
• 🛡️ Virus check.
• 🔄 Replacing the HDD with an SSD (this is not a hardware upgrade in the classical sense, but it gives a huge increase in speed).

If the laptop is more than 5 years old, even these measures may not help - then you should think about buying a new device.

❓ Which laptop should I buy if the old one is completely slow?

The choice depends on the tasks:

• 📝 Office/study: Lenovo IdeaPad 5, HP Pavilion (from 40,000 ₽).
