Has your laptop suddenly started “thinking” about every operation, programs take forever to open, and the cursor freezes on the screen? This is not a reason to urgently run to the service center. In 90% of cases, brakes are caused by software problems that you can fix yourself - even without special skills. The key is to correctly diagnose the cause and apply targeted solutions.

We analyzed hundreds of cases of users complaining about slow laptops. Lenovo, HP, Asus, Acer And MacBook (including models on M1/M2). It turned out that even new devices with SSD And 16+ GB RAM may slow down due to hidden processes, outdated drivers, or suboptimal power settings. This article contains only working methods, sorted by efficiency and complexity of implementation.

1. Diagnostics: why did the laptop start to slow down?

Before you begin “treatment”, you need to identify the root of the problem. Brakes can be caused by:

  • 🔋 Overheating — dust in the cooling system or dried thermal paste reduces performance by 30-50%.
  • 🖥️ Lack of resources — too many programs are running, or one of them “eats” all the RAM.
  • 🦠 Malware — mining viruses, spyware or adware load the processor at 100%.
  • 🗑️ Cluttered system — temporary files, browser cache and fragmented disk slow down your work.
  • 🔄 Outdated drivers - especially relevant for video cards NVIDIA/AMD and network adapters.

To pinpoint the culprit, use the built-in diagnostic tools:

  • 🪟 B Windows: open Task Manager (Ctrl+Shift+Esc) → tab Performance. See which component is 80%+ loaded. If this Disk - the problem is HDD or background processes.
  • 🍎 On macOS: run System monitoring (Programs → Utilities) and check the tabs CPU, Memory And Disk.
  • 🐧B Linux: Enter the command in the terminal: 
    top

📊 How often does your laptop slow down?
  • Constantly
  • Only when running heavy programs
  • After updating Windows/macOS
  • Rare, but noticeable
  • Doesn't slow down (just checking)

Critical sign: if the laptop slows down even in Safe Mode (launched by key F8 when loading Windows), the problem is more likely a hardware one - a malfunction RAM, SSD/HDD or motherboard.

2. Quick solutions: 5 ways to speed up your laptop in 10 minutes

If you are short on time, start with these methods - they give an instant effect and do not require deep knowledge.

Disable startup of unnecessary programs

Clear browser cache (Chrome, Firefox, Edge)

Reboot your laptop (yes, it works!)

Disable Windows Visual Effects

Check for viruses with Malwarebytes

-->

2.1. Disable startup programs

Many applications (eg Skype, Discord, Steam) automatically launch when you turn on the laptop and consume resources in the background. To disable them:

  • 🪟 B Windows 10/11: Settings → Applications → Startup. Sort by parameter Impact on launch and disable everything except the antivirus.
  • 🍎 On macOS: System Preferences → Users and Groups → Login Items.

2.2. Clear your browser cache

Browsers (Google Chrome, Mozilla Firefox, Microsoft Edge) accumulate gigabytes of temporary files that slow down page loading. Clear cache:

  1. In your browser, click Ctrl+Shift+Del (or Cmd+Shift+Del on Mac).
  2. Select period For all time.
  3. Check the boxes Cookies, Cached Images And Other site data.
  4. Click Delete data.
💡

If you use Chrome, install the extension The Great Suspender — it automatically “freezes” inactive tabs, saving up to 40% of RAM.

2.3. Turn off Windows visual effects

Aero effects and animations are beautiful, but slow down on weak laptops. To disable them:

  1. Click Win+R, enter sysdm.cpl and press Enter.
  2. Go to the tab Additionally → Performance → Options.
  3. Select Provide the best performance and press OK.

2.4. Reboot your laptop (seriously!)

More than 60% of Microsoft and Apple support calls are resolved by a simple reboot. Many processes (especially those related to updates) hang in the background and slow down the system. If the laptop works without turning off for more than 3 days, force it to restart.

2.5. Check for viruses

Use Malwarebytes (free version) or built-in Windows Defender for scanning. Pay special attention to miners - they load the processor 100% and are almost invisible in Task Manager.

💡

If after rebooting the brakes disappeared, the problem was temporary OS failures. If not, move on to deep optimization.

3. Deep optimization: for advanced users

If express methods don't help, it's time to dig deeper. It will take a little more time here, but the result is worth it.

3.1. Update drivers (especially for the video card)

Outdated drivers are one of the main reasons for slowdowns in games and graphics programs. Update them manually:

  • 🎮 For NVIDIA: download the latest version from the website NVIDIA (select your video card model).
  • 🔴 For AMD: use the utility AMD Adrenalin.
  • 💻 For other devices: update drivers via Device Manager (Win+X → Device Manager).
How to find out the video card model?

Open Task Manager → tab Performance → GPU. In the upper right corner there will be the model name (for example, NVIDIA GeForce RTX 3050).

3.2. Clean the Windows Registry

Over the years of use, the registry becomes clogged with garbage from deleted programs. To clean, use CCleaner (free version):

  1. Download the program from the official website.
  2. Launch and select Register → Troubleshooting.
  3. Click Correct Selected and save a backup copy.

Attention! Do not edit the registry manually via regedit, if you are not sure of your actions, this can lead to system collapse.

3.3. Move swap files to another drive

If you have installed and SSD, and HDD, move the page file to the hard drive to relieve the load on the SSD:

  1. Click Win+R, enter sysdm.cpl → tab Additionally → Performance → Options → Additionally → Virtual memory → Edit.
  2. Uncheck Automatically select the size of the paging file.
  3. Select drive D: (or other HDD), specify the size (recommended 1.5 × amount of RAM) and press Set.
  4. For disk C: (where Windows is installed) select No swap file.

3.4. Disable Windows Search Indexing

The indexing function speeds up file search, but constantly loads the disk. To disable it:

  1. Open Control panel → Indexing Options.
  2. Click Edit and uncheck all folders.
  3. Click OK and reboot your laptop.

3.5. Check disk health

If the laptop slows down when reading/writing files, the problem may be HDD or SSD. You can check the disk status using:

  • 🪟 CrystalDiskInfo (shows SMART-status and temperature).
  • 🍎 B macOS: Disk Utility (Programs → Utilities).
  • 🐧B Linux: command smartctl -a /dev/sda.

Critical signs of disk failure:

  • 🚨 Reallocated Sectors Count > 0 - the disk begins to crumble.
  • 🚨 Pending Sectors > 0 - there are bad sectors.
  • 🚨 Temperature > 50°C - overheating.
💡

If CrystalDiskInfo shows status Anxiety or Bad — urgently backup your data and get ready to replace the disk.

4. Hardware causes of brakes: when to disassemble a laptop

If software methods do not help, the problem may lie in the hardware. Here's what to check first:

4.1. Cleaning dust and replacing thermal paste

Dust clogs the cooler and radiator, causing the processor and video card to overheat and trolled (automatically reduce performance). Signs of overheating:

  • 🌡️ The laptop gets very hot and makes noise (the cooler is running at maximum).
  • ⚡ Performance drops 10-15 minutes after switching on.
  • 🔄 Unexpected shutdowns or reboots.

To clean your laptop:

  1. Turn off the power and remove the battery (if removable).
  2. Unscrew the back cover (you need a Phillips screwdriver).
  3. Carefully remove dust from the cooler and radiator with a brush or a can of compressed air.
  4. If the thermal paste has dried out (becomes hard), replace it with new one (for example, Arctic MX-4).
💡

Do not use a vacuum cleaner for cleaning - it creates static electricity, which can damage components.

4.2. Checking RAM

Faulty strips RAM cause freezes, blue screens (BSOD) and random reboots. You can check your memory like this:

  • 🪟 B Windows: enter in search Memory Checker and reboot the laptop for the test.
  • 🐧B Linux: use the command: 
    sudo memtest86

If the test shows errors, try removing and reinserting the strips RAM. If errors remain, replace the memory.

4.3. Replacing HDD with SSD

Replacing the hard drive with an SSD speeds up the laptop by 3-5 times - this is the most effective upgrade for older devices. For example, a laptop with HDD And 4 GB RAM after installation SSD will work faster than a new laptop with HDD And 8 GB RAM.

Recommended Models SSD for upgrade:

Model Capacity Read/write speed Price (2026) Better for
Samsung 870 EVO 500 GB - 1 TB 560/530 MB/s from 4,500 ₽ Budget upgrade
Crucial MX500 250 GB - 2 TB 560/510 MB/s from 3,800 ₽ Reliability
WD Black SN850X 500 GB - 2 TB 7300/6300 MB/s from 7,000 ₽ Games and hard tasks
Kingston KC3000 512 GB - 2 TB 7000/6000 MB/s from 6,500 ₽ Laptops with PCIe 4.0

To transfer the system from HDD on SSD use programs Macrium Reflect or Clonezilla.

4.4. Battery check

A worn-out battery can cause sudden drops in performance, especially when the laptop is running on AC power. Check battery condition:

  • 🪟 B Windows: Enter at the command line: 
    powercfg /batteryreport

    The report will be saved in C:\Users\Your_name\battery-report.html. Look for the parameter Design Capacity vs Full Charge Capacity. If the difference is > 30%, it’s time to change the battery.

  • 🍎 On MacBook: hold Option and click on the battery icon in the menu bar. Status ReplaceSoon or ReplaceNow speaks for itself.

5. Optimization for specific tasks

The laptop may not slow down in all scenarios, but only in certain programs. Let's look at the most common cases.

5.1. Game lags

If games lag or crash, check:

  • 🎮 Graphics Settings: Reduce resolution to 1280×720 and turn off Ray Tracing, Anti-Aliasing.
  • 🔧 Video card drivers: Update to the latest version (see section 3.1).
  • 🔥 Overheating: use the utility MSI Afterburner to monitor GPU temperature.
  • 🖥️ Background processes: close Discord, browser and other programs via Task Manager.

For laptops with hybrid graphics (NVIDIA Optimus or AMD Switchable) force enable the discrete video card:

  1. Right click on the desktop → NVIDIA Control Panel.
  2. Select Managing 3D Settings → Software settings.
  3. Add the game to the list and select High performance NVIDIA processor.

5.2. Browser is slow

Browsers (Chrome, Firefox, Edge) are the main “eaters” of RAM. To speed them up:

  • 🧹 Clear extensions: remove unnecessary addons (especially AdBlock, if it has not been updated for a long time).
  • 🔄 Reset settings: in Chrome go to Settings → Restore settings.
  • 🚀 Use lightweight browsers: Opera GX (with RAM limit) or Brave.
  • 🛡️ Disable hardware acceleration: In your browser settings, find the option Use hardware acceleration and turn it off.

5.3. Brakes when working with video/photo

Programs like Adobe Photoshop, Premiere Pro or After Effects require a lot of resources. Optimize their work:

  • 🎨 Set up cache: in Photoshop go to Edit → Preferences → Performance and increase Memory Usage up to 70-80%.
  • 💾 Use proxy files: in Premiere Pro turn on Proxy Workflow for low resolution work.
  • 🖥️ Disable background processes: Close all programs except the editor.
  • 🔧 Update Adobe Creative Cloud: Older versions are often buggy.

5.4. Windows boots slowly

If the laptop turns on for more than 1-2 minutes:

  • ⚡ Disable Fast Startup: Control Panel → Power Options → What the Power Buttons Do → Change Settings → Uncheck Enable Fast Startup.
  • 🔄 Execute clean boot:
    1. Click Win+R, enter msconfig.
    2. Go to the tab Services, mark Don't show Microsoft services and press Disable everything.
    3. Restart your laptop.
  • 🗑️ Empty folder Temp: 
    Нажмите Win+R → введите %temp% → удалите все файлы

    • 6. Radical measures: when all else fails

    If all of the above methods fail, it’s time to consider extreme measures.

    6.1. Reinstalling Windows

    This is the last chance to return your laptop to its former speed. Before reinstalling:

    • 💾 Make a backup important files to an external drive or cloud.
    • 🔑 Find your activation key (use ProduKey from NirSoft).
    • 📥 Download the latest version of Windows from the official website Microsoft (link).

      • To reinstall:

      1. Create a bootable USB flash drive using Rufus or Media Creation Tool.
      2. Boot from the flash drive (F12 or Esc when turned on).
      3. Select Custom installation and format the disk C:.
      4. Install Windows and restore files from backup.

      Attention! After reinstallation, immediately install the drivers (especially for Wi-Fi and video cards) from the official website of the laptop manufacturer, and not through Windows Update.

      6.2. Hardware upgrade

      If the laptop is older than 5 years, perhaps its resources are simply not enough for modern tasks. Consider the following upgrades:

      • 🖥️ Add RAM: Maximum for most laptops - 16 GB (2 planks each 8 GB).
      • 💾 Replace HDD on SSD (see section 4.3).
      • 🔋 Replace the batteryif it is worn out (>500 charging cycles).
      • 🔌 Use a cooling pad with additional fans.

      Before purchasing components, check compatibility with your laptop model on the manufacturer’s website or through Crucial System Scanner.

      6.3. Alternative operating systems

      If the laptop is too weak for Windows 10/11, try light OS:

      • 🐧 Linux Mint or Ubuntu MATE: consume 2-3 times less resources than Windows.
      • 🪟 Windows 10 LTSC: version without unnecessary services and updates (suitable for weak PCs).
      • 🍎 ChromeOS Flex: from Google, works even on laptops with 2 GB RAM.

      For the test you can run Linux from a flash drive without installation (mode Live CD).

      7. Prevention: how to prevent brakes in the future

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

      • 🧹 Clean the system once a month with the help CCleaner or built-in utility Disk Cleanup.
      • 🔄 Reboot your laptop every 2-3 days (especially after installing updates).
      • 🛡️ Use a lightweight antivirus (Bitdefender, Kaspersky or built-in Windows Defender).
      • 📦 Remove unnecessary programs through Settings → Applications.
      • 🔋 Don't keep your laptop on charge all the time - This reduces battery life.
      • 🌡️ Control the temperature with the help HWMonitor or Core Temp.

      Attention! Never use "optimizers" like Advanced SystemCare or AVG TuneUp — they often install unnecessary software and become the cause of the slowdowns themselves.
