The laptop is very slow - what should I do? Complete instructions for speeding up

Does your laptop take longer to boot than the kettle takes to boil water? Applications open in slow motion, and the mouse cursor gets stuck under the slightest load? Brakes are one of the most common problems that users encounter 1-3 years after purchase. But do not rush to take the device to the service: 90% of cases You can eliminate the cause yourself without spending money on diagnostics.

In this article - step by step analysis all possible causes of slowdown, from simple system blockage to hardware faults. We will look at solutions for Windows 10/11 And macOS, and we will also give recommendations for an upgrade if software methods do not help. We will pay special attention to hidden performance “eaters” that are not written about in standard guides - for example, background processes of NVIDIA drivers or OneDrive services, which can eat up to 30% of the CPU.

1. Diagnostics: how to determine the cause of the brakes

Before treatment, a diagnosis must be made. Brakes may be caused by software (viruses, overloaded OS) or hardware (iron wear, overheating) problems. Let's start with a basic check:

Open Task Manager (Ctrl+Shift+Esc for Windows or Activity Monitor on macOS) and pay attention to:

• 📈 CPU load: If the processor is loaded at 80–100% for no apparent reason, look for viruses or background processes.
• 💾 RAM usage: if the RAM is full to capacity (90%+), the system starts using the swap file on the hard drive - this is 10–20 times slowerthan RAM.
• 🔥 Temperature: If the CPU or video card overheats (above 85°C), throttling is triggered - a forced decrease in performance.
• 💿 Loading the disc: 100% HDD/SDD activity indicates problems with drivers or viruses (for example, miners).

For in-depth diagnostics, use the following utilities:

• 🛠️ HWMonitor (Windows) - Shows temperature, voltage and load on all components.
• 🖥️ CrystalDiskInfo — checks the health of the hard drive/SSD (critical if the indicator Reallocated Sectors Count above 0).
• 🍎 iStat Menus (macOS) - an analogue of the Task Manager with advanced metrics.

⚠️ Attention: if the laptop started to brake suddenly after updating Windows or drivers, roll back the system to the previous restore point (Win+R → rstrui). In 40% of cases this solves the problem.

2. System cleaning: remove junk and unnecessary programs

Over time, your laptop becomes clogged with temporary files, cache, and programs that you haven't used for a long time. It's like clutter in a closet - the more you have, the harder it is to find what you need. Let's start with general cleaning:

Step 1: Remove unnecessary programs

• 🧹 Go to Control Panel → Programs → Programs and Features (Windows) or Finder → Programs (macOS).
• 🗑️ Delete everything you haven’t used in the last 6 months. Pay special attention to:
• 🎮 Game launchers (Epic Games, Ubisoft Connect, Battle.net — they work in the background even when games are not running).
• 📱 Drivers for old devices (printers, smartphones).
• 🛒 Trial versions of antiviruses (McAfee, Norton - they often remain after the license expires).

Step 2: Clear temporary files

Use built-in tools:

• 🪟 Windows: Win+R → cleanmgr → select drive C: → tick all the boxes.
• 🍏 macOS: Finder → Go → Go to Folder → enter ~/Library/Caches and delete all contents.

Step 3. Cleaning startup

Many programs are added to startup without your knowledge. To disable unnecessary things:

• 🖱️ Windows: Ctrl+Shift+Esc → Startup → disable everything except antivirus and drivers.
• 🍎 macOS: System Preferences → Users and Groups → Login Items.

To automate, use the utilities:

• 🧼 CCleaner (Windows) - Cleans the registry and temporary files.
• 🚀 OnyX (macOS) - optimizes the system and clears the cache.

⚠️ Attention: do not use “optimizers” like Advanced SystemCare or MacKeeper - they often aggravate brakes by adding your own background processes.

3. Fight against viruses and miners

If your laptop suddenly starts to slow down, especially when working in a browser, there is a risk of infection virus or miner. Miners use your CPU/GPU resources to mine cryptocurrency, and Trojans can steal data in the background.

Signs of infection:

• 🔥 High CPU load (50–100%) without running programs.
• 🌐 Slow browser performance, even on simple sites.
• 🔌 Fast battery drain (viruses actively use the CPU).
• 📁 The appearance of unknown processes in the Task Manager (for example, svchost.exe with high load).

How to check and remove:

1. Download Malwarebytes or Kaspersky Virus Removal Tool - they are free and do not require installation.
2. Run full check (not fast!).
3. Remove any threats found and reboot your laptop.
4. Check your browser extensions: remove anything suspicious (especially ones with names like AdBlock Pro, HD for YouTube - these are often masks for miners).

For advanced users: check your network connections via netstat -ano on the command line. If you see suspicious IP addresses (for example, from China or Russia, if you don’t live there) - this is a sign of a botnet.

How to remove a miner manually?

If the antivirus fails, open Task Manager, find the process with a high CPU load (for example, msiexec.exe or conhost.exe in an unusual location), right-click → Open file storage location → delete the folder with the virus. Then check Job Scheduler (taskschd.msc) for suspicious tasks.

4. Optimizing Windows and macOS: hidden settings

Even a “clean” system can slow down due to non-optimal settings. Let's consider hidden tweaks, which are rarely mentioned in standard guides.

For Windows 10/11:

• 🎨 Turn off visual effects:
• Go to System → Advanced system settings → Performance → Options.
• Select Provide the best performance or manually disable window and shadow animations.
• 🖼️ Disable background apps:
• Settings → Privacy → Background apps → turn off everything except what is necessary.
• 🔄 Set up a swap file:
• If you have less than 8 GB RAM, increase the page file to 1.5 × amount of RAM.
• If 16 GB+ RAM - turn it off completely (Control Panel → System → Additional. settings → Performance → Advanced → Virtual memory).

For macOS:

• 🖥️ Disable unnecessary widgets:
• Swipe right on the desktop → tap Edit → remove all widgets except calendar and weather.
• 🔍 Set up Spotlight:
• System Preferences → Siri and Spotlight → Privacy → add folders that do not need to be indexed (for example, /Downloads).
• 📁 Clear system services cache:
• Open Terminal and enter:

sudo periodic daily weekly monthly
sudo rm -rf /Library/Caches/*
sudo rm -rf ~/Library/Caches/*

5. Hardware problems: overheating, dust, wear and tear

If software methods do not help, the problem may lie in gland. The most common hardware causes of brakes:

Problem	Signs	Solution
Overheating	The laptop gets very hot, the fans work at maximum, there are sudden freezes	Cleaning dust, replacing thermal paste, using a cooling pad
HDD wear	Long system loading times, freezes when opening files, clicks from the case	Replacement with SSD, checking SMART status (CrystalDiskInfo)
Faulty RAM	Blue screens (BSOD), random reboots, slowdowns when working with large files	Check MemTest86, replacing the memory stick
Low battery	The laptop slows down without connecting to the network, suddenly turns off	Replacing the battery or operating from mains with the battery removed
Motherboard failure	Artifacts on the screen, spontaneous shutdowns, ports do not work	Diagnostics at the service center

How to clean your laptop from dust yourself:

1. Turn off your laptop and remove the battery (if possible).
2. Unscrew the back cover (on most models Lenovo, HP, Dell it can be removed easily; at Apple MacBook you will need a special screwdriver P5).
3. Blow out the fan and radiator compressor or can of compressed air (not with a vacuum cleaner!).
4. Remove the cooler and clean the blades with a cotton swab dipped in alcohol.
5. Replace the thermal paste on the processor and video card (use Arctic MX-6 or Noctua NT-H2).

⚠️ Attention: if you have never disassembled laptops, it is better to entrust the cleaning to a service. 70% of breakdowns after self-disassembly associated with damage to the cables or improper assembly.

6. Upgrade: when is it time to change hardware

If the laptop is more than 5 years old, even optimization will not save you from slowdowns. In this case it will help upgrade. Let's look at what can be improved:

1. Replacing HDD with SSD

This the most effective upgrade for old laptops. SSD speeds up system boot time 3–5 times, and opening programs in 10–20 times. For example:

• 💿 Samsung 870 EVO (1 TB) - the best choice for most laptops.
• 💾 WD Black SN850X — for gamers and working with video.
• 🍏 For MacBook Pro/Air (2012–2015) will do OWC Aura Pro X2.

2. Increase RAM

Minimum requirements for comfortable work in 2026:

• 📝 Office tasks (Word, Excel, browser) — 8 GB.
• 🎮 Games (GTA V, Cyberpunk 2077) — 16 GB+.
• 🎬 Video editing (Premiere Pro, DaVinci Resolve) — 32 GB.

3. Replacing thermal paste and cooler

If the laptop overheats, even cleaning may not help - the thermal paste dries out over time. Best options for replacement:

• 🧪 Arctic MX-6 - universal, does not conduct current.
• 🔥 Thermal Grizzly Kryonaut - for extreme cooling (for example, for MSI GT76 or ASUS ROG).

4. External video card (for stationary operation)

If you have a laptop with Thunderbolt 3/4 (For example, MacBook Pro or Dell XPS), you can connect an external video card via the box:

• 🖥️ Razer Core X + NVIDIA RTX 4060 Ti - for games and rendering.
• 🎨 Sonnet eGFX Breakaway Box + AMD RX 6700 XT - for working with graphics.

7. Alternative solutions: cloud PCs and thin clients

If an upgrade is too expensive or impossible (for example, in MacBook Air M1 cannot be replaced with SSD), please consider alternative ways:

1. Cloud PC

Services like Shadow, GeForce NOW or Amazon WorkSpaces allow you to rent a powerful virtual computer and connect to it from any device. Pros:

• ⚡ Instant access to top-end hardware (for example, RTX 4090 or Threadripper).
• 💰 There is no need to buy a new device.
• 🔒 Data is stored in the cloud - safe if your laptop is stolen.

Cons: requires stable Internet (from 50 Mbit/s).

2. Thin client

If the laptop is used only for office tasks, you can turn it into a thin client for connecting to a remote desktop (RDP) or Citrix. This will relieve local resources.

3. Lightweight OS

Replace Windows with a Linux distribution optimized for weak hardware:

• 🐧 Lubuntu - for laptops with 2–4 GB of RAM.
• 🦊 Puppy Linux - works even on Pentium 4.
• 🌐 ChromeOS Flex - official firmware from Google for older PCs.

FAQ: Frequently asked questions about laptop brakes

❓ Why does the laptop slow down immediately after turning it on?

Most likely the problem is startup — too many programs are running at the same time. Open Task Manager (Ctrl+Shift+Esc), go to the tab Autoload and turn off everything unnecessary. Also check your laptop for viruses - some miners are activated when the system starts.

❓ Can slow internet cause slowdowns?

Yes, but indirectly. If you have weak Wi-Fi or limited data, browser and cloud applications (for example, Google Docs) will slow down. However, this does not affect the performance of local programs (for example, Photoshop or Word). Check the speed at Speedtest - if it is below 10 Mbit/s, contact your provider.

❓ Should you disable Windows updates?

No! Disabling updates may result in security vulnerabilities. Instead:

• Set your active hours (Settings → Update & Security → Change active hours) so that updates are not installed while running.
• Disable driver updates via Windows Update (Settings → Update & Security → Advanced settings → Updates for other Microsoft products).

❓ Why did the new laptop start to slow down after a month?

Most often this is due to:

• 🗑️ Littering — installed games, programs, browser cache.
• 🔥 Overheating - check the temperature in HWMonitor.
• 🛡️ Antivirus - some (for example, Norton) heavily load the system. Replace with Bitdefender or built-in Windows Defender.
• 🔄 Background processes - disable synchronization OneDrive/Google Drive, if you don't use it.

❓ How to speed up a laptop for gaming?

Critical for gamers:

1. Update your video card drivers (NVIDIA GeForce Experience or AMD Adrenalin).
2. Disable Game DVR And Game Bar on Windows (Settings → Games).
3. Install Razer Cortex — it optimizes the system for games.
4. Lower the graphics settings in the game (especially Shadows And Particle effects).
5. Use DDU (Display Driver Uninstaller) to completely clean up old drivers before updating.
