Why the laptop slows down: it works very slowly, it takes a long time to turn on / off and boot Windows 7

Many users face the problem of slow laptop performance. Let's look at ten main reasons why a laptop takes a long time to turn on.

Operating system

The operating system and hard drive become overwhelmed with information over time. When the laptop is running, the programs used are not always removed correctly. This leads to various conflicts in the operation of the system. The more programs installed and running at the same time, the higher the likelihood of crashes leading to slower laptop performance.

Eliminating the cause: It is recommended to regularly use programs for complex maintenance of the operating system registry in order to avoid this problem. For example, Reg Organizer is a multifunctional program for comprehensive maintenance of the Micorosoft Windows system registry. Carries out cleaning of the registry, its compression and defragmentation. It also has a registry editor and an advanced search and replace data function, previews imported reg-files (including from Explorer). Reg Organizer performs a complete removal of the software, cleaning up all the "tails" remaining in the system after the usual uninstallation.

File fragmentation

The laptop needs periodic defragmentation to help sort and organize the logical partitions of the disk on which the operating system files are located.

Eliminating the cause: Defragmentation is best done with specialized programs.

Defragment your hard drive

Open Disk Defragmenter. To do this, click the Start button. In the search box, type Disk Defragmenter, and then select Disk Defragmenter from the list of results. In the Current Status section, select the disk that you want to defragment.

To determine if disk defragmentation is required, click Analyze. If you are prompted for an administrator password or confirmation, enter the password or provide confirmation.

When Windows finishes analyzing the disk, the Last Start column will show the percentage of disk fragmentation. If this value is more than 10%, you must defragment the disk.

Click the Disk Defragmenter button. If you are prompted for an administrator password or confirmation, enter the password or provide confirmation.

Registry entries

Slow operation of the laptop is facilitated by a large number of programs in the startup of the operating system.

Eliminating the cause: Remove unnecessary programs from startup. All programs in use are displayed on the lower right side of the laptop screen when you press the Start button. For prophylaxis, use programs that correct entries in the registry.

For example, WinHacker 95 - changes icons, renames and deletes service folders, varies various Windows settings.

Win-eXpose-Registry - tracks calls to the Registry with the ability to filter by the type of access. You can print the log file from the program, but you cannot save it to the desired location. In addition, you cannot navigate to a changed, created, or deleted key.

Registry Search + Replace - scans and replaces parameters in the Registry not only of the local, but also of the remote computer, and in the keys of certain types, with the subsequent saving of all settings.

Virus check

There are viruses that do not manifest themselves for a long time. But in the active phase, they slow down the laptop.

Eliminating the cause: launch the antivirus program.

Open the main window of the antivirus program, go to the "Scan hard drives" or "Scan PC" menu.In the window that appears, define the scan settings for your computer.

For a more thorough scan, choose the most powerful option - "Deep Scan". After that, we indicate the hard drives and other devices on which we will scan for and remove viruses.

If necessary, we can fine-tune the scanning and file checking parameters. After that we press the "Scan" button.

During scanning, the antivirus will detect suspicious files and then offer to perform one of the actions on them. Usually antivirus offers:

  • deleting a file;
  • moving a file to quarantine;
  • skip the file (leaving everything unchanged);
  • clean the file from viruses.

Select one of the actions and press the "OK" button.

If after running the anti-virus program the virus remains on the computer, you must remove it yourself. Specify the name of the file to delete to the anti-virus program To do this, open the folder where the damaged file is stored, and click on it with the right mouse button and select one of the actions in the menu that appears (for example, "Check for viruses").

In the event that the antivirus did not find suspicious data in a file or several files, but you know that the file contains a virus, select this file or several files and press the shift + del combination.


The processor power of a dual-core laptop is drained by applications running in the background.

Eliminating the cause: View running programs in the task manager. Stop and delete not used by you. Replace the required CPU-intensive programs with the ones that work correctly. Do this carefully and if you are not sure, then contact more experienced people.

Hard disk sector

The reason for the slow operation of the laptop is the appearance of bad sectors on the hard disk. This is a "disease" of laptops that are more than two to three years old.

Eliminating the cause: Periodically check the disk for bad sectors. The built-in Windows disk surface diagnostic tools will help you with this. Third party software is just as effective.

Cooling system

When the temperature rises to a critical one, the overheating protection system is triggered. Spontaneous shutdown is possible. The bottom of the laptop is hot and the fan is noisy.

Eliminating the cause: cleaning the laptop from dust, you can read about it in our article "Why is the laptop warming up?" or contact a service center to clean the laptop.

Power supply system

When running on battery power, laptops enter power saving mode. This reduces the speed of the processor.

Eliminating the cause: Correct the power saving settings. They optimize battery performance, balance energy consumption.

Requirement for the program

Your laptop for everyday tasks has served you for over a year. You bought a new resource-intensive game. Due to the high load, the laptop slows down.

Eliminating the cause: increase the RAM to the maximum. Other laptop upgrades are not recommended.
