Has your laptop become slower than a snail in a marathon? Apps take forever to open, videos lag, and the cursor freezes at the most inopportune moments? Don’t rush to run to a service center or buy a new device. In 90% of cases, the problem can be solved on your own - often even without financial investments.

Laptop brakes are not a death sentence, but a signal that the system needs attention. The reasons can be very different: from clogged garbage hard drive until overheating processor, from viruses to outdated Windows (or other OS). In this article, we will analyze all possible scenarios - from simple to complex - and give clear instructions on how to return your laptop to its former agility. And if you are not confident in your abilities, then at least you will understand what you are paying the master for.

Let's start with diagnosis - this is half the success. Without it, any action can be useless or even harmful. For example, if the brakes are caused malfunction of an SSD drive with more than 70% service life, then no amount of software optimization will help - an upgrade or replacement is needed. Now let's get down to business.

1. Diagnostics: why is the laptop slow?

Before treatment, a diagnosis must be made. Brakes can be caused by both software and hardware problems. Here are the key symptoms and their possible causes:

  • 🐢 Laptop turns on and off slowly → Autorun loaded, the disk is fragmented or the system is damaged.
  • 🔥 The case gets very hot, the fan is noisy → Overheating due to dust, dried thermal paste or a malfunction of the cooler.
  • 🖥️ The screen “freezes” for a few seconds → RAM problems (low memory or module errors).
  • 💾 Files take a very long time to copy → HDD on the verge of death or the SSD is full to capacity.
  • 🦠 Strange windows, advertisements, redirects appear → Viruses or malware.

Use built-in tools for accurate diagnostics Windows:

  1. Click Win + R, enter msinfo32 and check the section Conflicts/problems.
  2. Open Task Manager (Ctrl+Shift+Esc) and sort processes by load on CPU, memory And disk.
  3. Run Command Prompt as administrator and run the command: 
    wmic diskdrive get status

    If the disk status Pred Fail — make a backup urgently!

If the laptop slows down even in Safe Mode (launched by key F8 when loading), the problem is most likely a hardware one. If everything works quickly in safe mode, the software is to blame.

📊 How often do you clean your laptop from dust?
  • Once a month
  • Once every six months
  • Only when it starts to warm up
  • Never

2. System cleaning: remove junk and unnecessary programs

Over time, digital junk accumulates on the laptop: temporary files, cache, remnants of deleted programs. It's like dust in a room - it's unnoticeable, but it makes it difficult to breathe. Let's start with something simple:

  • 🧹 Disk Cleanup: open This computer, right-click on the system disk (C:), select Properties → Disk Cleanup. Delete temporary files, recycle bin, old restore points.
  • 🗑️ Removing unnecessary programs: go to Settings → Applications → Apps & features. Remove everything you don't use (especially McAfee, Norton and other “antiviruses” that themselves slow down the system).
  • 🔍 Find duplicates: use utilities like Duplicate Cleaner or CCleaner (but be careful with the latter - they sometimes delete the necessary files).

Pay special attention to the folders:

C:\Users\<Ваше_имя>\AppData\Local\Temp

C:\Windows\Temp


C:\Users\<Ваше_имя>\Downloads

They can be safely cleaned by hand. And if you are afraid of deleting something important, move the files to another folder and check if anything is broken.

3. Optimization of startup and services

One of the main reasons for a laptop to boot slowly is an overloaded startup. Many programs (especially Skype, Discord, Steam) are added there without asking and slow down the system from the first seconds.

How to clean startup:

  1. Open Task Manager (Ctrl+Shift+Esc).
  2. Go to the tab Autoload.
  3. Disable everything except antivirus, video card drivers and critical utilities (for example, Synaptics for touchpad).

Also check Windows services:

  1. Click Win + R, enter msconfig.
  2. Go to the tab Services.
  3. Check the box Don't show Microsoft services.
  4. Disable suspicious services (such as those related to Bonjour, QuickTime or unknown manufacturers).

If you are not sure what to disable, use the utility Autoruns from Microsoft. It shows all startup items, including hidden ones.

💡

Don't disable the service Superfetch (aka SysMain) on HDD - this will degrade performance. But on an SSD you can safely turn it off.

4. Fight against viruses and malware

Viruses and mining bots are a common cause of slowdowns. They steal CPU, memory and network resources, turning your laptop into a “zombie”. Even if you have an antivirus installed, this is not a guarantee of security.

What to do:

  • 🛡️ Scan with standard Windows Defender:
    1. Open Settings → Update & Security → Windows Security.
    2. Select Protection against viruses and threats → Quick scan.
    3. If it finds threats, remove them and restart the laptop.
  • 🔍 Deep scanning with third-party utilities:
    • Malwarebytes — finds what antiviruses miss.
    • AdwCleaner — cleans adware and browser extensions.
    • Kaspersky Virus Removal Tool - portable scanner from Kaspersky.
  • 🕵️ Check for mining: open Task Manager and see if any process is loading video card or CPU 100% without reason. Common culprits: svchost.exe (if not from Microsoft), lsass.exe (if it consumes a lot of memory).

    • If the antivirus doesn’t find anything, but the laptop still slows down, try resetting browsers:

    • B Chrome: Settings → Reset settings.
    • B Firefox: Help → Troubleshooting → Clean Firefox.
    How to remove an uninstallable virus?

    If a virus blocks the installation of antiviruses or prevents you from booting into the system:

    1. Download Kaspersky Rescue Disk to another computer.

    2. Write the image to a USB flash drive (with the program Rufus).

    3. Boot from the flash drive (in BIOS, select boot from USB).

    4. Perform a complete scan and treatment.

    5. Update drivers and system

    Outdated drivers are like driving on flat tires: possible, but very ineffective. Drivers are especially critical for video cards, chipset And network adapters.

    How to update drivers correctly:

    • 🔄 Automatic update via Windows:
      1. Open Settings → Update & Security → Windows Update.
      2. Click Checking for updates.
      3. Install all available updates (including optional ones).
  • 🎮 Video card drivers:
    • For NVIDIA: download from the site NVIDIA.
    • For AMD: from the site AMD.
    • For Intel: through Intel Driver & Support Assistant.
  • 🔧 Drivers for chipset and other hardware:
    • For laptops Lenovo, HP, Dell etc. download drivers only from manufacturer's official website (according to laptop model).
    • Don't use programs like Driver Booster - They often install incompatible or outdated drivers.

    • If after updating the drivers the laptop starts to slow down even more, roll them back:

    1. Open Device Manager (Win + X → Device Manager).
    2. Find the problematic device (for example, video card), right-click → Properties → Driver → Roll Back.
    💡

    Never update drivers through "Driver Update" in Device Manager - Windows often installs generic drivers that work worse than the original ones.

    6. Hardware problems: overheating, RAM, storage

    If software methods don't help, it's time to look under the case. Most often, brakes are caused by:

    Problem Symptoms Solution
    Overheating The laptop turns off, slows down under load, the fan is noisy Cleaning dust, replacing thermal paste, checking the cooler
    Lack of RAM Slow operation with browser tabs, freezing when opening programs Adding a memory stick or replacing it with a more capacious one
    Dying HDD/SSD Long copying of files, freezes, reading errors Replacement with a new drive (preferably SSD)
    Weak processor Lags in games, slow video processing, 100% CPU usage Software optimization or upgrade (if possible)

    How to check overheating:

    • Install HWMonitor or Core Temp.
    • Run a stress test (eg Prime95 for CPU or FurMark for video card).
    • If the temperature exceeds:
      • CPU: 85°C under load (for Intel) or 95°C (for AMD Ryzen).
      • Video card: 80–85°C (for NVIDIA), 90–95°C (for AMD).

    If the temperature is high, the laptop needs to be cleaned. To do this:

    1. Turn off the power, remove the battery (if removable).
    2. Unscrew the bottom cover (look for instructions on the model on YouTube).
    3. Blow off the dust with a compressor or brush. Be careful with cooler blades!
    4. Remove the old thermal paste from the processor and video card (if any), apply new one (for example, Arctic MX-4).
    ⚠️ Attention: If you have never disassembled a laptop, it is better to take it to a service center. Assembly errors can lead to damage to the cables or motherboard.

    If you have HDD, not SSD — replacing it will give the most noticeable increase in speed (3-5 times!). Enough for office work Samsung 870 EVO or Crucial MX500 for 500 GB. For games and heavy tasks, take 1 TB.

    7. Optimizing Windows for Maximum Performance

    Windows 10 And Windows 11 by default they are configured to balance between performance and beauty. But if the laptop is weak, you can sacrifice visual effects for speed.

    What you can disable:

    • 🎨 Visual effects:
      1. Open Settings → System → Advanced system settings.
      2. In the section Performance click Options.
      3. Select Provide better performance or manually disable animations.
    • 📊 Background applications:
      1. Go to Settings → Privacy → Background apps.
      2. Disable everything except system processes.
    • 🔄 Search indexing:
      1. Open Services (services.msc).
      2. Find Windows Search, right click → Properties → Startup type: Disabled.

    For Windows 11 additionally:

    • Disable widgets (right click on the taskbar → Widgets → Disable).
    • Bring back the classic menu Start through StartAllBack or OpenShell (saves up to 10% of resources).

      • If you have SSD, be sure to check if the mode is turned on AHCI:

      1. Open Device Manager.
      2. Expand IDE ATA/ATAPI controllers.
      3. If the controller name contains AHCI - everything is fine. If IDE - you need to switch through the BIOS.

      8. Radical measures: reset, reinstallation, upgrade

      If all else fails, it’s time to think about radical measures. Here's what you can do:

      • 🔄 Reset Windows to factory settings:
        1. Open Settings → Update & Security → Recovery.
        2. Select Restore your computer to its original state.
        3. Save your personal files (if necessary) and start the process.
      ⚠️ Attention: After the reset, you will have to reinstall programs and configure the system. But this is often the only way to get rid of deep-seated viruses or “crooked” updates.
    • 🖥️ Reinstalling Windows from scratch:
      • Download Media Creation Tool from the site Microsoft.
      • Create a bootable USB flash drive (minimum 8 GB).
      • Boot from the USB flash drive and install the system again.

      This is an extreme method, but it is guaranteed to remove everything unnecessary. After installation, do not forget to install the drivers!

    • 🔧 Hardware upgrade:
      • Adding RAM: if you have 4 GB, increase to 8–16 GB (4 GB is catastrophically small for modern tasks).
      • Replacing HDD with SSD: As already mentioned, this will give 最大的 a speed boost.
      • Replacing thermal paste and cleaning: If your laptop is running hot, even a simple cleaning can restore 20-30% of its performance.

      • If your laptop is older than 7-8 years, it may be time to consider a replacement. Modern challenges (e.g. Photoshop, AutoCAD or games) require not only a powerful processor, but also support for new instructions (AVX2, SSE4.2), which may not be present in old Intel Core 2 Duo or AMD Athlon.

      💡

      Before reinstalling Windows, be sure to save your license key using the utility ProduKey from NirSoft. It will be useful for activation after a clean installation.

      FAQ: Frequently asked questions about laptop brakes

      The laptop only slows down when playing games. What to do?

      Most likely the problem is with the video card drivers or overheating. Update drivers (see section 5), check temperature (MSI Afterburner) and reduce the graphics settings in the game. Also make sure that the game is running from a discrete graphics card (not the built-in one). To do this:

      1. Right click on the desktop → NVIDIA/AMD Control Panel.
      2. Find the game in the list and select a high-performance GPU for it.
      Laptop slows down after Windows update. How to roll back?

      If the brakes started after the update, try rolling back:

      1. Open Settings → Update & Security → Recovery.
      2. Click Start in section Go back to a previous version of Windows.

      If the button is inactive, it means more than 10 days have passed and the rollback point has been deleted. Then only a reset or reinstallation will help.

      Is it possible to speed up a laptop with 2GB RAM?

      Technically yes, but not significantly. Here's what you can do:

      • Install Windows 10 LTSC or Linux Xubuntu - they are less demanding on memory.
      • Disable all background processes (see section 3).
      • Use easy program analogues: LibreOffice instead of Microsoft Office, Pale Moon instead of Chrome.
      • Add another 2–4 GB of RAM (if there is a free slot).

      But honestly: 2 GB in 2026 is very little. Even for office work it is better to have at least 4 GB.

      The laptop is slow on Linux. What's the matter?

      Linux usually runs faster than Windows, but there are problems here too:

      • 🐧 Check your video card drivers. For NVIDIA install proprietary drivers: 
        sudo ubuntu-drivers autoinstall
      • 🖥️ If you use GNOME or KDE — try lighter environments: XFCE, LXQt or MATE.
      • 🔄 Disable unnecessary services: 
        sudo systemctl list-units --type=service

        And disable unnecessary commands sudo systemctl disable servicename.

      Should you use “optimizers” like CCleaner or Advanced SystemCare?

      No, it's not worth it. These programs often:

      • They delete the necessary files, breaking the system.
      • They add themselves to startup, slowing down the laptop even more.
      • They collect your data (many “optimizers” are spyware).

      All their functions can be done manually (see sections 2 and 3). Exception - BleachBit (for Linux) and built-in Disk Cleanup on Windows.
