A slowdown in your computer\u2019s performance inevitably affects your productivity. The machine takes ages to execute commands, apps are slow to open, and frustration builds. Faced with a struggling PC, optimisation becomes a priority.<\/span><\/p>\n

It is perfectly possible to regain control of the situation. This simple, practical guide walks you through six steps to <\/span>diagnose weaknesses and restore your system\u2019s speed<\/b>.<\/span><\/p>\n

Identify what\u2019s causing the slowdown<\/span><\/h2>\n

In most cases, the main reason for a slowdown is <\/span>overloaded system resources<\/b>. When too many operations run at the same time, the processor and RAM struggle to keep up.<\/span><\/p>\n

There are two sides to fixing this: reducing the number of operations the system has to process, and increasing the hardware capacity of the machine. This article covers both software tweaks and hardware upgrades.<\/span><\/p>\n

1. Clear out active processes<\/span><\/h2>\n

Your first line of defence is to shut down applications that run without your say\u2011so or that unnecessarily use resources in the background.<\/span><\/p>\n

    \n
  • Essential tool:<\/b> Open <\/span>Task Manager<\/span><\/i> by pressing <\/span>Ctrl + Alt + Del<\/b> at the same time.<\/span><\/li>\n
  • See the impact:<\/b> The <\/span>Processes<\/span><\/i> tab shows exactly how much CPU and memory each program is using.<\/span><\/li>\n
  • Instant response:<\/b> Simply closing the programs you don\u2019t need can give you an <\/span>instant performance boost<\/b>.<\/span><\/li>\n<\/ul>\n

    If you only use a piece of software occasionally, or you\u2019ve forgotten it\u2019s even there, uninstalling it is an effective way to free up space and memory.<\/span><\/p>\n

    Manage programmes that start with Windows<\/span><\/h2>\n

    Many programmes start automatically when you switch on your computer, which makes boot time longer.<\/span><\/p>\n

      \n
    • Access the settings:<\/b> Go back into <\/span>Task Manager<\/span><\/i> and click the <\/span>Startup<\/span><\/i> tab.<\/span><\/li>\n
    • Careful selection:<\/b> This list shows every program that launches automatically. <\/span>Limit this auto\u2011start<\/b> to essential software by using the disable option at the bottom.<\/span><\/li>\n<\/ul>\n

      2. Keep your web browser in good shape<\/span><\/h2>\n

      If your computer mainly slows down when you\u2019re browsing the internet, it\u2019s time to focus on your browser.<\/span><\/p>\n

        \n
      • Update it:<\/b> Make sure you\u2019re running the <\/span>latest version of your browser<\/b>. Turn on automatic updates.<\/span><\/li>\n
      • Clean it up:<\/b> Extensions and add\u2011ons, even if they look lightweight, can use a lot of resources. Open the <\/span>Add\u2011ons<\/span><\/i> or <\/span>Extensions<\/span><\/i> menu and <\/span>remove anything you don\u2019t really need<\/b>.<\/span><\/li>\n<\/ul>\n

        3. Optimise performance on a hard disk drive (HDD)<\/span><\/h2>\n

        On mechanical hard drives (<\/span>HDD<\/span><\/i>), seek time is a major cause of slowness because the fragments of related files are often scattered across the disk.<\/span><\/p>\n

          \n
        • Why defragment:<\/b> Defragmentation reorganises chunks of data on the drive so that related elements are grouped together. This <\/span>reduces the time needed to read a file<\/b> and speeds up the whole system.<\/span><\/li>\n
        • How to do it (Windows):<\/b> From the Start menu or the <\/span>Windows<\/span><\/i> button, go to <\/span>Control Panel<\/span><\/i>, then <\/span>System and Security<\/span><\/i>. The tool is under <\/span>Administrative Tools<\/span><\/i> (look for <\/span>Defragment your hard drive<\/span><\/i>).<\/span><\/li>\n
        • Scheduling:<\/b> You can set defragmentation to run on a regular schedule, or start it manually after analysing the state of the disk.<\/span><\/li>\n<\/ul>\n

          Reminder: <\/span>Never defragment solid\u2011state drives (SSD)<\/b> as they use a different storage technology.<\/span><\/p>\n

          4. Work out if the hardware is the bottleneck<\/span><\/h2>\n

          The two hardware components that have the most direct impact on your computer\u2019s speed are storage and RAM. Upgrading these parts can make an <\/span>older machine faster than it was when new<\/b>, and it\u2019s far more affordable than buying a whole new computer.<\/span><\/p>\n

          Storage that\u2019s too slow or not enough memory are the main <\/span>bottlenecks for performance<\/b> and multitasking.<\/span><\/p>\n
