Slow Computer performance

Problem Type: Software and Hardware

A slow computer is a source of frustration for many users. However, this computer problem can be caused by numerous reasons, some mentioned below, along with their solutions.

Maxed Out Disk Space

When a computer's storage device, whether an HDD (Hard Disk Drive) or an SSD (Solid State Drive), is nearly full, it can affect the system's performance differently. A full disk can lead to file fragmentation for HDDs, where parts of files are scattered across the drive. This fragmentation forces the drive head to move to different physical locations to read a single file, significantly increasing access times and slowing down the system.

In contrast, SSDs, which use flash memory, do not suffer performance degradation due to fragmentation in the same way, as they can access data instantaneously regardless of its location on the drive. However, keeping an SSD near full capacity can still impact its performance and longevity due to limitations on write cycles and the need for proper wear leveling. Thus, regardless of the type of drive, maintaining adequate free space is crucial for ensuring optimal system responsiveness and longevity of the storage device.


Cleaning unnecessary files from your drives is essential to regain your PC's performance speed. However, it's crucial to proceed with caution and avoid deleting system files that are vital for the smooth operation of your Windows operating system. Here's how you can safely clean your computer:

  1. Start with the Basics: Begin by emptying the Recycle Bin and deleting obvious junk files such as watched movies, images, and other unnecessary items. This simple step can free up a surprising amount of space on your hard drive.
  2. Cloud Storage and External Drives: If you're unsure about deleting certain files directly from your drives, consider transferring data to a cloud server or storing it on an external hard drive or an SSD. This way, you can free up space on your computer without permanently losing access to your files.

Critical System File Locations to Avoid

While cleaning your PC, it's vital to steer clear of specific directories where Windows stores its system files. Tampering with these locations can lead to serious system stability issues. Here's a quick overview of these critical areas:

  • Windows Folder: Primarily located on the C: drive, this directory and its subfolders, like "System32" and "SysWOW64," contain crucial system programs and libraries.
  • Program Files and Program Files (x86): These contain files for installed programs. "Program Files" is used for 64-bit applications, while "Program Files (x86)" houses 32-bit apps on 64-bit systems.
  • Users Folder: This includes personal files, settings, and the "AppData" subfolder, which holds application-specific data. Be cautious not to remove files from here without understanding their purpose.
  • Windows\System32: A critical directory for system operation containing essential DLLs and drivers.
  • Windows\SoftwareDistribution: Used by Windows Update, it's generally safe to clear its contents to resolve update issues but avoid unnecessary tampering.
  • Windows\Prefetch: This helps speed up program loading. The system manages it automatically, and manual intervention is not recommended.
  • Windows\WinSxS (Side by Side): Critical for the functionality of multiple applications and Windows features, particularly in managing updates and DLL versions.

By respecting these guidelines and focusing on safe areas for cleanup, you can improve your computer's performance without risking system health. Always remember, when in doubt about a file's importance, it's safer to research or consult a professional before deletion of System files.

Note: Consider downloading a PC tune-up application for a hands-off approach. Such software can help automate the cleaning process, reducing manual effort and the risk of accidentally deleting important files.

Program Running in The Background

Background applications, including system services and user-installed software, consume system resources such as CPU and RAM. It can lead to slower system performance as these resources are divided among more processes, especially if these applications are resource-intensive. Users might not be aware of these processes running, as they can start automatically at boot or run hidden in the system tray.

  1. Manage Startup Applications
Disabling Startup apps from Task Manager

To prevent unnecessary programs from slowing down your computer right from startup, you can manage which applications automatically run at boot:

  • Right-click the Taskbar and select Task Manager.
  • Switch to the Startup apps tab.
  • Here, you'll see a list of applications that start automatically when your computer boots. Carefully review this list, and for any application you don't need immediately at startup, right-click it and choose Disable.

This action doesn't uninstall the applications but prevents them from auto-starting, freeing up resources.

2. Use Task Manager for Active Applications
  • Press (Ctrl+Shift+Esc) or (Ctrl+Alt+Del) and select Task Manager to open it.
  • Navigate to the Processes tab to see all running applications and background processes.
