How to Make Your Computer Run Faster: A Practical Guide

Make Computer Run Faster with These Steps

A slow computer frustrates, but most fixes are simple and free. Before you consider buying a new machine, try the practical steps below. They address the usual causes of sluggish performance, from startup clutter to malware, and they work across Windows and macOS.

Free Up Disk Space

When your hard drive fills up, your computer slows down because it needs free space for temporary files and virtual memory. Aim to keep at least 15 to 20 percent of your main drive empty.

• Run Disk Cleanup (Windows) or Storage Management (macOS) to remove temporary files, empty the recycle bin, and delete old downloads.
• Uninstall programs you no longer use.
• Move large files like photos and videos to an external drive or cloud storage.

Disable Startup Programs

Many applications launch automatically when you start your computer and run quietly in the background, consuming memory and processor cycles.

• On Windows, open Task Manager, go to the Startup tab, and disable unnecessary entries.
• On macOS, go to System Settings, then General, then Login Items, and remove or disable items you do not need at startup.

Restart your computer after making changes to see the effect.

Check for Malware and Unwanted Software

Malware and adware can run hidden processes that eat up CPU and network resources. Run a full scan with your built-in antivirus or a reputable third-party scanner. On Windows, Microsoft Defender provides a solid baseline scan. On macOS, Malwarebytes is a common choice for occasional scans. If you find unwanted programs, remove them and reset your browser settings if needed.

Update Your Operating System and Drivers

Updates often include performance improvements and bug fixes. Keeping your system current helps your hardware work as intended.

• On Windows, go to Settings, then Windows Update, and install all available updates.
• On macOS, go to System Settings, then Software Update.
• Check for graphics and chipset drivers from your manufacturer, especially if you notice stuttering or slow graphics.

Adjust Visual Effects and Power Settings

Operating systems include animations and visual effects that look nice but use processing power. You can turn them down or off to gain speed.

• On Windows, search for "Adjust the appearance and performance of Windows," choose "Adjust for best performance," or customize which effects to keep.
• On macOS, go to System Settings, then Accessibility, then Display, and turn on Reduce motion.
• Set your power plan to High Performance on Windows when plugged in, or choose the Best Performance mode on macOS.

Add More RAM or Switch to an SSD

Hardware upgrades can make a noticeable difference, especially on older machines.

If your computer still uses a traditional hard drive, switching to an SSD is one of the single biggest speed improvements you can make. Check your device specifications before purchasing parts.

Reset or Reinstall the Operating System

If your computer remains slow after trying the steps above, a clean reinstall can help. This removes accumulated software clutter and resets system settings. Back up your files first, then use the built-in reset or reinstall option in your operating system. On Windows, search for "Reset this PC"; on macOS, use Disk Utility and Reinstall macOS after restarting into Recovery mode.

When to Consider a New Computer

Sometimes the hardware is simply too old to benefit from software fixes. If your machine cannot support current updates, lacks RAM upgrade options, or uses an older processor that struggles with modern workloads, a new computer may be the most practical choice. Look for models with an SSD and at least 8 GB of RAM for everyday tasks.
