Why does the laptop take a long time to load when turned on - a complete analysis of the reasons

You pressed the power button, but instead of the usual 20-30 seconds, the screen lights up after 5 minutes? Or does the laptop “hang” on the manufacturer’s logo, spin “loading” for an eternity, and then suddenly come to life? This problem is familiar to every fifth user - according to StatCounter, 18% of calls to service centers are related specifically to slow loading of the OS. But in 80% of cases it can be solved on your own without spending money on diagnostics.

In this article we will look at all possible reasons - from clogged startup to hardware faults, and we’ll also give step by step instructions for Windows 10/11 and macOS. You will learn how to identify the “culprit” of the brakes (even if you are new to IT), what programs and settings to check first, and when it’s really time to take your laptop in for repair. Spoiler: in 60% of cases it is not the hardware that is to blame, but the software!

1. Overloaded startup is the main “brake” of Windows

If laptop takes a long time to load after the Windows logo (at the stage of the appearance of the desktop), autoloading is to blame in 95% of cases. Messengers, cloud storage, games (for example, Steam or Epic Games), driver updates and even viruses. Each such program “eats off” from 5 to 30 seconds when the system starts.

How to check? Click Ctrl + Shift + Esc, go to the tab Autoload. Displayed here influence time each application to boot the OS. If there are more than 10 items on the list or there are programs marked “High”, this is a critical signal.

• 🔍 Diagnostics: Sort the list by the Load Impact column. Programs marked “High” or “Medium” are prime candidates for disabling.
• ⚡ Solution: Right-click on the unnecessary application → “Disable”. For macOS: System Preferences → Users and Groups → Login Items.
• ⚠️ Exceptions: Do not disable your antivirus (for example, Kaspersky or Bitdefender) and video card drivers (for example, NVIDIA GeForce Experience).

Critical information: If there are unknown processes with random names in startup (for example, svchost.exe *32 in several copies) is a sign of a virus. Scan your system immediately Malwarebytes or Dr.Web CureIt!.

2. Fragmented or full disk

If laptop takes a long time to load at the Windows logo stage (before the spinning dots appear), the problem may be in the disk. Two scenarios:

1. HDD is fragmented — OS files are “scattered” across the disk, and the head has to physically “run” between sectors. On SSD this effect is less noticeable, but still present.
2. The disk is full - Windows requires a minimum of 10-15% free space for temporary files. If on disk C: With less than 5 GB left, the system will slow down.

How to check? For Windows: open This computer, right click on the disk C: → Properties → Service → Optimize. If the “Current Status” column shows more than 10% fragmentation, the disk needs to be defragmented. For macOS: use the utility Disk Utility (in Programs → Utilities).

Problem	Signs	Solution
HDD fragmentation	Long loading times, freezes when opening files	Defragmentation via Disk optimization or Defraggler
Full disk	"Not enough space" errors, slow performance	Cleaning via Disk Cleanup or CCleaner
Damaged sectors	Freezes, BSOD (blue screen)	Check chkdsk /f /r on the command line

Delete temporary files via Disk Cleanup

Transfer large files (videos, games) to another drive

Disable hibernation (powercfg /h off in CMD)

Check the disk for errors (chkdsk /f)

3. Outdated drivers or hardware conflicts

If laptop takes a long time to load at the POST stage (before the Windows/macOS logo appears), the problem may be driver or hardware conflicts. Typical symptoms:

• 🖥️ The screen goes blank for 10-30 seconds while loading.
• 🔊 The fans suddenly start making more noise.
• 🔄 The laptop reboots 2-3 times before the OS starts.

The most problematic drivers are drivers video cards (especially on laptops with NVIDIA Optimus), chipset And network adapters. For example, after updating Windows 11, many users Lenovo Legion And ASUS ROG encountered a “black screen” for 2-3 minutes due to a driver conflict NVIDIA And Intel Iris Xe.

How to fix:

1. Update drivers manually via Device Manager (right click on Start → Device Manager).
2. For the video card, download the driver from the official website (NVIDIA, AMD or Intel).
3. If the problem appears after the update, roll back the driver (in Device Manager → Properties → Rollback).

How to check for driver conflicts in Windows?

Open Control Panel → Administrative Tools → Event Viewer → Windows Logs → System. Look for errors with the code 41 (unexpected shutdown) or 14 (problems with drivers).

⚠️ Attention: If after updating the drivers the laptop stops turning on at all (black screen, no response to buttons), try booting into safe mode (hold Shift on reboot) and rollback the changes. If this does not help, you need to flash the BIOS or replace the video card (relevant for laptops with NVIDIA Maxwell/Pascal).

4. Viruses and malware

If laptop suddenly started taking a long time to load (for example, yesterday everything was fine, but today the download takes 10 minutes), the primary reason is viruses. Particularly dangerous:

• 🕵️‍♂️ Miners (For example, WannaMine) - use CPU/GPU resources to mine cryptocurrency.
• 📁 Rootkits (For example, Necurs) - disguise themselves as system processes and slow down loading.
• 🔄 Adware (For example, AdLoad) - adds itself to startup and opens browser windows.

How to check? Run a scan Kaspersky Virus Removal Tool or Dr.Web CureIt! in safe mode. Pay attention to the processes in Task Manager:

• Unknown programs with random names (for example, win32host.exe).
• Processes that consume 50-100% CPU during the boot phase.
• Network activity (tab Network) without your participation.

If the antivirus does not find anything, but suspicions remain, check task scheduler:

1. Click Win + R, enter taskschd.msc.
2. Check the sections Task Scheduler Library → Microsoft → Windows.
3. Remove unknown tasks (especially those with "On startup" or "On login" triggers).

5. Problems with BIOS/UEFI or power settings

If laptop It takes a long time to load even before the Windows logo appears (for example, hanging on the screen ASUS/HP/Lenovo more than 1 minute), the problem may be:

• 🔋 BIOS settings — slow boot mode is enabled (Legacy Mode instead of UEFI).
• 🔄 Boot device queue — the system is trying to boot from a flash drive or network drive.
• ⚡ Power mode - enabled in BIOS Power Saving Mode, which limits performance.

How to fix:

1. Go to BIOS (usually the button F2, Del or Esc when turned on).
2. Check the following settings:
   • Boot Mode → should be UEFI (not Legacy).
   • Secure Boot → enable (if disabled).
   • Fast Boot → enable (speeds up the POST test).
   • Boot Order → yours should come first SSD/HDD.

Save changes (F10) and reboot.

For Windows also check power plan:

1. Open Control Panel → Power Options.
2. Choose a plan High performance.
3. Click Set up power plan → Change advanced settings and make sure that:
   • Hard disk → Disable hard disk via → Never.
   • USB → USB Temporary Disable Option → Prohibited.

⚠️ Attention: If after changing the BIOS the laptop stops turning on (black screen, power indicator blinking), try resetting the BIOS settings - remove the battery and turn off the power for 30 seconds, then hold the power button for 10 seconds. If this does not help, you will need to flash the BIOS via Crisis Recovery Mode (relevant for laptops ASUS, MSI, Gigabyte).

6. Hardware faults: from RAM to motherboard

If all software methods have been tried, but the laptop still takes 5-10 minutes to load, the problem may be in the hardware. The most common faults:

Component	Symptoms of a problem	How to check
Random access memory (RAM)	Freezes, BSOD with errors MEMORY_MANAGEMENT or IRQL_NOT_LESS_OR_EQUAL	Test MemTest86 (minimum 4 passes)
Hard disk (HDD)	Clicks, rattles, freezes when reading files	CrystalDiskInfo (check the parameter Reallocated Sectors)
SSD	A sharp drop in speed, recording errors	HD Tune (check Health Status)
Motherboard	The laptop does not turn on, there is no image, but the fans are working	Checking with a multimeter (voltage on capacitors)

If you suspect RAM, follow these steps:

1. Turn off the laptop, disconnect the power and battery.
2. Remove all RAM sticks (unclip the clips on the sides).
3. Wipe the contacts with an eraser (to remove oxidation).
4. Insert the strips back (if there are several of them, try one at a time).
5. Run MemTest86 from a flash drive (minimum 2 hours of test).

For HDD/SSD use utilities:

• 🛠️ CrystalDiskInfo — will show the disk status (parameters Reallocated Sectors, Pending Sectors).
• 📊 HD Tune — will check the read/write speed (norm for SSD: 400+ MB/s).
• 🔧 Victoria — will find bad sectors (in mode Remap).

⚠️ Attention: If CrystalDiskInfo shows status Pred Fail (pre-failure state) or parameter Reallocated Sectors more than 100 - the disk needs to be replaced urgently! Even if it is still running, the risk of data loss is 90%. Transfer important files to another drive and prepare to buy a new one SSD (we recommend Samsung 980 Pro or WD Black SN850X).

7. Windows updates or system crashes

If laptop Started to take a long time to load after Windows update, to blame:

• 🔄 Unsuccessful update (For example, KB502xxxxx, which “breaks” the bootloader).
• 🗑️ Damaged system files (due to sudden power failure during update).
• 🔧 Driver conflict (especially after major updates like Windows 11 23H2).

How to fix:

1. Roll back the update:
   • Go to Settings → Update and security → Update history.
   • Click Uninstall updates and remove the latest installed packages.
2. Restore system files:

   DISM /Online /Cleanup-Image /RestoreHealth
   sfc /scannow

   (run as administrator in CMD).

3. Reset Windows to factory settings:
   • Settings → Update & Security → Recovery → Reset PC.
   • Select Save my files (so as not to lose data).

For macOS:

1. Boot into Recovery Mode (hold Cmd + R when turned on).
2. Select Reinstall macOS (data will not be deleted).
3. If the problem persists, perform a reset NVRAM (Cmd + Option + P + R when turning on, hold for 20 seconds).

FAQ: Frequently asked questions about laptop loading slowly

❓ The laptop takes a long time to load after replacing the HDD with an SSD. What to do?

Most likely, you did not transfer the system correctly or did not enable the AHCI in BIOS. Follow these steps:

1. Make sure it is enabled in BIOS AHCI Mode (not IDE).
2. Reinstall Windows on the SSD from scratch (cloning the old system may transfer errors).
3. Update your chipset drivers and NVMe-controller from the laptop manufacturer's website.

If the SSD is still slow, check its health in CrystalDiskInfo - you may have bought a fake (a common problem with cheap ones) Kingston A400 or Silicon Power).

❓ Why does the laptop take a long time to load after sleep or hibernation?

This is a typical Windows 10/11 problem related to:

• 🔋 Video card drivers (especially on laptops with NVIDIA Optimus).
• 🔄 hibernation file (hiberfil.sys), which is damaged.
• ⚡ Power settings (The Balanced plan may limit performance.)

Solutions:

1. Disable hibernation: run in CMD (from admin) command powercfg /h off.
2. Update your video card and chipset drivers.
3. B Control Panel → Power Options select plan High performance.

❓ Can an antivirus cause slow loading?

Yes, especially if it is:

• Kaspersky Internet Security (scans all files when downloading).
• Avast or AVG (known for conflicts with Windows 11).
• ESET NOD32 (may block system processes).

Solutions:

1. Add folder exceptions C:\Windows And C:\Program Files in the antivirus settings.
2. Disable startup scanning (in the "Protection" or "Boot Screen" settings).
3. Try a different antivirus (for example, Bitdefender or built-in Windows Defender).

❓ The laptop takes a long time to load after connecting the second monitor. Why?

This is due to:

• 🖥️ Video card drivers — the system is trying to determine the configuration of the displays.
• 🔌 Mode Duplicate/Extend - if monitors have different resolutions, Windows spends time scaling.
• ⚡ Food - some laptops (Dell XPS, HP Spectre) limit performance when connected to a docking station.

Solutions:

1. Update your video card drivers (Intel UHD, NVIDIA or AMD).
2. B Settings → System → Display select your primary monitor (click Define).
3. Disable scaling for the second screen (in the same display settings).

❓ How to speed up the boot time of a laptop running Linux (Ubuntu, Mint)?

On Linux, slow loading is usually due to:

• 🐧 Services systemd — some services freeze at startup.
• 🔧 Driver conflicts (especially with NVIDIA or Broadcom Wi-Fi).
• 📦 Snap packages — they auto-boot and slow down the system.

Solutions:

1. Check service loading times:

   systemd-analyze blame

   Disable slow services:

   sudo systemctl disable имя_службы.service

2. Install proprietary drivers for the video card:

   sudo ubuntu-drivers autoinstall

3. Disable snap packages (if not used):

   sudo systemctl disable snapd.service
   sudo systemctl disable snapd.socket
