The laptop freezes and takes a long time to load: what to do in 2026?

Has your laptop started to work like a retired “old man”: it opens programs for 5 minutes, freezes when watching videos, and sometimes even refuses to respond to clicks? Don't rush to take it to a service center or buy a new one. In 80% of cases, the problem can be solved on your own - often it is not the hardware that is to blame, but software failures, overheating or a clogged system.

We analyzed hundreds of cases with models Lenovo ThinkPad, ASUS ROG, HP Pavilion And Acer Swift, and also studied the reports of repairmen - and compiled a checklist of actions that will return your device to its former performance. Even if you've never delved into the settings of Windows or macOS, our instructions will help you figure it out without the risk of breaking something. Let's start with the simplest and end with the “heavy artillery” for advanced cases.

1. Diagnostics: why is the laptop slow?

Before treatment, a diagnosis must be made. Brakes can be caused by a dozen reasons - from a harmless background clogged with autoloading to critical wear and tear. SSD/HDD or processor overheating. Here are the key “symptoms” and their possible causes:

• 🐢 Long boot time for Windows/macOS (more than 2-3 minutes) - startup, fragmented disk or file system failures are to blame.
• ⚡ Freezes when opening programs - lack of RAM (RAM) or “sagging” of the processor due to overheating.
• 🔥 Sudden shutdowns or heavy braking — 90% probability that the laptop overheats due to dust or dried thermal paste.
• 💾 Constant disk loading at 100% (checked in Task Manager) - a sign of viruses, system failures Windows Search or drive wear.

To avoid guessing, start by checking Task Manager (for Windows: Ctrl+Shift+Esc). Sort processes by load on CPU, Memory And Disk. If some unknown process is eating up 50% of resources, this is a reason to check the system for viruses. If standard services are to blame (for example, svchost.exe), the problem is deeper - system files may be damaged.

2. Cleaning startup and background processes

The most common cause of brakes is startup, full of programs that you haven’t used for a long time. For example, Skype, Steam, NVIDIA GeForce Experience or even Adobe Creative Cloud can run along with the system and consume resources in the background. How to clean:

1. On Windows: open Start → Task Manager → Startup. Disable everything except the antivirus and drivers (for example, for the touchpad or video card).
2. On macOS: go to System Preferences → Users and Groups → Login Items.
3. Use utilities like CCleaner (just download from the official website!) or Autoruns from Microsoft for deep cleaning.

Pay special attention services. For example, Superfetch (in Windows 10/11 called SysMain) is often to blame for the disk being 100% loaded. To disable:

1. Нажмите Win + R, введите services.msc
2. Найдите службу SysMain
3. Кликните правой кнопкой → Свойства → Тип запуска: Отключена

⚠️ Attention: Don't disable services with names Windows Update, Antimalware Service Executable (this is Windows Defender) or drivers for Wi-Fi/Bluetooth. This may lead to system inoperability or vulnerabilities.

3. Overheating: how to check and fix

If the laptop starts to slow down after 10-15 minutes of use or suddenly turns off, it is almost certainly overheats. Normal processor temperature under load: up to 80–85°C. If it’s higher, it’s time to act.

First check the temperature using the programs:

• 🌡️ HWMonitor (Windows)
• 🌡️ iStat Menus (macOS)
• 🌡️ Core Temp (shows the temperature of each core)

If the temperature exceeds 90°C, the reasons may be:

Reason	How to check	Solution
Cooling system clogged with dust	Shine a flashlight into the vents	Clean the laptop with compressed air or have it serviced
Dried thermal paste	Temperatures rise even when idle	Replace thermal paste (requires disassembly)
Cooler malfunction	The fan does not spin or is noisy	Replace cooler
Throttling	CPU frequency drops below base	Reset BIOS settings or update firmware

Can be used for emergency cooling stand with coolers (For example, Cooler Master NotePal X3) or simply raise the laptop to improve air circulation. But this is a temporary solution - if the dust is not removed, the problem will return in a month.

What happens if you ignore overheating?

Prolonged overheating reduces the life of the processor and video card by 2–3 times. In critical cases it may occur crystal dump (microcracks on the processor), after which the laptop will have to be thrown away.

4. Viruses and malware: how to detect and remove

Viruses are a classic cause of slowdowns, but many users still underestimate it. Modern miners (for example, WannaMine) can use up to 70% of the processor power, and Trojans like Emotet load the network and disk in the background. Signs of infection:

• 🛡️ Unknown processes in Task Manager (for example, msiexec.exe with high load).
• 🛡️ Advertising in the browser, even if the blocker is installed.
• 🛡️ Spontaneous opening of windows or changing the home page.

To check use:

1. Built-in Windows Defender (update databases via Settings → Update & Security → Windows Defender).
2. Malwarebytes — finds what antiviruses miss.
3. Kaspersky Virus Removal Tool — a portable utility for in-depth scanning.
4. AdwCleaner — specializes in adware.

If a virus is found but cannot be removed, boot into Safe Mode (When Windows starts, hold Shift + F8) and repeat the scan. For macOS use XProtect (built-in protection) or Avast Security.

5. Disk optimization: from cleaning to replacement

If your laptop is equipped HDD (not SSD), slowdowns when downloading and opening files are almost inevitable. Even a “healthy” hard drive is 5–10 times slower than a modern one NVMe SSD. But even with an SSD there can be problems:

• 📁 Fragmentation (relevant for HDD) - files are “scattered” across the disk, and the head has to constantly jump.
• 🗑️ Clogged cache and temporary files — take up space and slow down indexing.
• ⚠️ Cell wear (for SSD) - if the disk has been in use for more than 3-5 years, its speed drops.

What to do:

1. Disk Cleanup:
   • On Windows: Start → System → Device storage → Disk Cleanup.
   • On macOS: Programs → Utilities → Disk Utility → First Aid.
2. Defragmentation (only for HDD!):

   1. Откройте командную строку (Win + R → cmd).
   2. Введите: defrag C: /U /V (замените C на букву вашего диска).

3. Checking disk health:
   • For Windows: CrystalDiskInfo (shows S.M.A.R.T. data).
   • For macOS: diskutil verifyVolume / in the Terminal.

⚠️ Attention: If CrystalDiskInfo shows status Pred Fail (pre-failure) or parameter Reallocated Sectors Count is growing - urgently copy the data and get ready to replace the disk. Such symptoms foreshadow the imminent death of the drive.

If the disk is healthy, but slows down, consider upgrade to SSD. For example, replacing HDD with Samsung 870 EVO or Crucial MX500 will speed up Windows boot from 2-3 minutes to 10-15 seconds. For laptops with M.2 slot will do WD Black SN850X - it is 6 times faster than a standard SATA SSD.

6. Update drivers and BIOS

Outdated or broken drivers are a common cause of slowdowns, especially after updating Windows. For example, video card driver NVIDIA The 2021 version may conflict with Windows 11, causing games or graphics programs to lag. How to update drivers correctly:

• 🔧 Automatically:
  • On Windows: Start → Settings → Update & Security → Windows Update → View additional updates.
  • On macOS: System settings → Software update.
• 🔧 Manually (more reliable):
  • Video card: download the driver from the website NVIDIA/AMD/Intel.
  • Wi-Fi/Bluetooth: Check with your laptop manufacturer's website (e.g. support.lenovo.com).
  • Chipset: update via Intel Driver & Support Assistant or AMD Chipset Drivers.

Special attention - BIOS. Outdated firmware can cause conflicts with new hardware or Windows. Update the BIOS only if:

• There are critical bugs (for example, the laptop does not recognize the new processor).
• The manufacturer has released a patch for vulnerabilities (for example, Spectre or Meltdown).

⚠️ Warning: Continuously updating the BIOS is dangerous - if the process is interrupted (for example, due to a power outage), the laptop can turn into a “brick”. Use UPS (uninterruptible power supply) and make sure that the battery charge is at least 50%.

7. Extreme measures: system reset and upgrade

If all else fails, it’s time to consider radical methods. Let's start with the safest:

1. Reset Windows/macOS to factory settings:
   • On Windows: Settings → Update & Security → Recovery → Reset PC (select "Keep my files").
   • On macOS: Restart your laptop → Hold Command + R → Disk Utility → Erase Volume → Reinstall macOS.

   This will remove all programs but keep documents, photos and music.

2. Clean Windows installation:

   If the reset does not help, create a bootable USB flash drive with the latest version of Windows (use Media Creation Tool) and install the system from scratch. Don't forget to save your data to an external drive first!

3. Hardware upgrade:

   If the laptop is more than 5 years old, even a clean system can slow down due to weak hardware. What can be improved:

   • 🖥️ RAM: add another stick (for example, from 8 GB to 16 GB). Enough for office work Crucial SODIMM DDR4.
   • 💾 SSD: replace HDD with NVMe (if there is a slot M.2) or SATA SSD.
   • 🔋 Battery: if the laptop only works from the mains, the battery is worn out (check in HWMonitor parameter Wear Level).

For laptops Apple (For example, MacBook Pro 2015–2017) the upgrade is often limited to replacing the SSD. In models late 2018 and newer, the hardware is sealed, and all that remains is a clean installation of macOS or contacting service.

FAQ: Frequently asked questions about laptop brakes

My laptop only slows down when playing games. What's the problem?

Most likely the culprits are:

• Outdated video card drivers (update via GeForce Experience or AMD Adrenalin).
• Overheating (check the temperature in MSI Afterburner).
• Lack of RAM (modern games require at least 16 GB).
• Background processes (close Discord, a browser with a dozen tabs, Steam).

Also check the graphics settings in the game - perhaps anti-aliasing is enabled or shadows are set to maximum, which your video card cannot handle.

The laptop takes a long time to boot after updating Windows. What to do?

Windows updates often break drivers or conflict with programs. Try:

1. Roll back update: Settings → Update & security → View update history → Uninstall updates.
2. Launch sfc /scannow in the command line (as administrator) to restore system files.
3. Disable fast startup: Control Panel → Power Options → What the Power Buttons Do → Change Unavailable Settings → Uncheck “Enable Fast Startup”.

The MacBook began to slow down after updating to the new macOS. How to restore speed?

New versions of macOS (for example, Sonoma or Ventura) may slow down on older MacBooks (2015–2017). Solutions:

• Reset NVRAM And SMC (instructions on the website Apple).
• Disable visual effects: System Preferences → Accessibility → Display → Reduce Transparency.
• Remove unnecessary languages and architectures via Monolingual (saves up to 5 GB of space).
• If all else fails, roll back to the previous version of macOS via Time Machine.

The laptop freezes when connected to Wi-Fi. What's the matter?

The problem may be:

• Wi-Fi adapter driver (update on the laptop manufacturer’s website).
• Conflict with IPv6 (disable it in Control Panel → Network Adapters → Properties → IPv6 Protocol).
• Router overload (reboot it or change the channel in the settings).
• Viruses using the network (check Malwarebytes).

Also try connecting to another network (for example, from a phone via USB tethering) - if the brakes disappear, the problem is with the router or provider.

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

Most “optimizers” are a waste of time or even harmful. Here's the truth about popular programs:

• CCleaner: Useful for clearing the cache, but it's best not to use its Registry feature - it often breaks the system.
• Advanced SystemCare: Aggressively deletes files, which can cause programs to crash.
• Avast Cleanup: Plagiarize Windows features that can be done manually.

It's better to use built-in tools (Disk Cleanup, Defragmentation) or proven utilities like BleachBit (for Linux/Windows).
