Why is Computer Startup Slow?

There are many reasons why your computer might be starting up slowly, but some of the most common causes are:

  1. Too many startup programs: Many programs automatically start when you turn on your computer, which can slow down the startup process.
  2. Corrupted system files: If the files that your operating system needs to start up are corrupted, it will take longer to boot.
  3. Hard drive issues: If your hard drive is full or damaged, your computer may take longer to start.
  4. Malware or viruses: These pesky creatures can infect your system and slow down the startup process.
  5. Outdated hardware: If your computer is outdated, it may not be able to keep up with the demands of newer software and take longer to start.

Note: Other reasons like hard disk problems, power supply issues, and overheating are also common.

How to Fix Slow Startup Manually

If you’re feeling confident, you can try to fix the slow startup manually by following these steps:

  1. Remove unnecessary startup programs: To do this, go to the Task Manager (Ctrl + Alt + Del) and click on the Startup tab. Disable the programs that you don’t need.
  2. Run a virus and malware scan: Use your preferred antivirus software to scan your computer for malware and viruses.
  3. Check your hard drive: Use the CHKDSK command to scan your hard drive for errors. Open the Command Prompt (Win + R) and type in “chkdsk /f /r C:” (replace C with the letter of your hard drive).
  4. Update your drivers: Outdated drivers can cause issues, so it’s important to keep them up to date. You can do this manually by going to the manufacturer’s website or using driver update software.

Microsoft Windows 10 and 11 are vulnerable to tons of applications trying to load in the startup. The high number of running processes is also another cause. Make sure to uninstall all unneeded applications, especially those that stay active in the background.

Pro tip! A great method to diagnose hardware problems is to reboot in Safe Mode. This is a special Windows mode that will only load the minimum drivers and startup apps. From the Safe Mode environment, you will be able to uninstall drivers and recently installed apps that might have caused the problem.

If your computer performance has worsened only recently or after installing some application then you might try a System Restore. Windows takes automatic snapshots of the system, especially after a driver installation.

In the image above you can see that Windows has created a restore point after the installation of the application TunelBear.

To find the restore menu go to Settings – System (left bar tab) – System Protection – System Restore. Click on Next or choose a different restore point, and Windows will highlight the reason for the snapshot. If it is a scheduled backup or after the installation of some drivers/applications.

After deciding on the appropriate restore point, the system will restore and reboot automatically.
