How to Fix Low Memory on PC (Step-by-Step Guide)

Experiencing frustrating slowdowns, crashes, or error messages like ‘Your computer is low on memory’? These are classic signs that your PC needs attention. Low memory, often referring to insufficient RAM (Random Access Memory), can bring your productivity to a halt. Fortunately, there are many effective ways to address this issue. Below, we’ll walk you through a comprehensive guide on how to fix low memory on PC, helping you regain your computer’s speed and stability. If these steps seem too complex, remember that Brilliant Tech is always here to provide expert remote support.

Step 1: Close Unnecessary Programs and Browser Tabs

One of the quickest ways to free up RAM is to close any applications, programs, or browser tabs you’re not actively using. Each open program consumes a portion of your system’s memory. Browsers, especially with many tabs open, are notorious memory hogs. Go through your taskbar and system tray, closing everything you don’t need. You might be surprised how much memory is freed up by simply decluttering your digital workspace. This is often the first and most effective step when you encounter a ‘low memory’ warning.

Step 2: Restart Your Computer Regularly

A simple restart can work wonders. Over time, your operating system and various applications can accumulate ‘memory leaks’ or processes that don’t release memory properly after they’re closed. Restarting your computer clears the RAM completely, giving you a fresh start. Make it a habit to restart your PC every day or two, especially if you leave it running for extended periods. This fundamental action helps clear temporary files and resets all processes, often resolving transient low memory issues.

Step 3: Check for Malware and Viruses

Malicious software can run in the background, consuming significant system resources, including memory, without your knowledge. If your PC suddenly starts experiencing low memory issues, accompanied by unusual pop-ups or extremely slow performance, a malware infection could be the culprit. Run a full scan using a reputable antivirus program. Keeping your antivirus software up-to-date is crucial for preventing such issues and ensuring your system’s health. Brilliant Tech can help you identify and remove stubborn malware.

Step 4: Adjust Virtual Memory (Paging File)

Windows uses a ‘paging file’ (or virtual memory) on your hard drive to supplement your physical RAM. When your physical RAM is full, Windows moves less frequently used data from RAM to this paging file. If you have plenty of free disk space, increasing the size of your virtual memory can alleviate low memory warnings. To do this, go to ‘System Properties’ -> ‘Advanced system settings’ -> ‘Performance Settings’ -> ‘Advanced’ tab -> ‘Change’ under ‘Virtual memory’. Uncheck ‘Automatically manage paging file size’ and set a custom size. Be careful not to make it too large, as it uses hard drive space.

Step 5: Disable Unnecessary Startup Programs

Many applications are configured to launch automatically when your computer starts, even if you don’t need them immediately. These startup programs consume RAM from the moment you log in. Open Task Manager (Ctrl+Shift+Esc), go to the ‘Startup’ tab, and disable any programs you don’t need running in the background. Be cautious not to disable essential system services or security software. Disabling these can significantly speed up your boot time and free up memory.

Step 6: Update Device Drivers and Windows

Outdated or corrupted device drivers can sometimes cause memory leaks or inefficient resource usage. Ensure your graphics card driver, chipset drivers, and other critical device drivers are up-to-date. Additionally, make sure your Windows operating system is fully updated. Microsoft frequently releases updates that include performance improvements and bug fixes, which can help optimize memory usage. Keeping your system current is a simple yet powerful way to maintain performance and fix low memory issues.

Step 7: Run Disk Cleanup and Delete Temporary Files

Accumulated temporary files, system logs, and other junk files can not only take up valuable disk space but sometimes contribute to system sluggishness, indirectly affecting memory management. Use the built-in Disk Cleanup tool in Windows (search for ‘Disk Cleanup’) to remove these unnecessary files. Select your main drive, then choose which file types to delete, including ‘Temporary files’, ‘Recycle Bin’, and ‘Temporary Internet files’. This frees up disk space, which can be crucial if your virtual memory relies on it.

Step 8: Uninstall Unused Software

Just like startup programs, software you rarely or never use can still consume resources or take up disk space that could be used for virtual memory. Go to ‘Settings’ -> ‘Apps’ -> ‘Apps & features’ and uninstall any programs you no longer need. This declutters your system, potentially removing background processes and freeing up resources. It’s a good practice to periodically review your installed applications and remove bloatware. This contributes to a healthier system overall and helps fix low memory problems.

Step 9: Increase Physical RAM (Hardware Upgrade)

If your PC consistently suffers from low memory warnings despite trying all software-based solutions, and you frequently run memory-intensive applications (like video editing, CAD, or heavy gaming), it might be time for a hardware upgrade. Adding more physical RAM is often the most effective solution for chronic low memory issues. Before purchasing, check your motherboard’s specifications for compatible RAM types and maximum capacity. Brilliant Tech can advise you on the best RAM upgrade options for your specific PC model.

Step 10: Scan for System File Corruption

Corrupted system files can lead to a multitude of Windows issues, including inefficient memory usage. Windows has a built-in tool called the System File Checker (SFC) that can scan for and repair corrupted system files. To use it, open Command Prompt as an administrator and type ‘sfc /scannow’ then press Enter. Let the scan complete. If SFC finds issues it can’t fix, you might also try the DISM (Deployment Image Servicing and Management) tool for a more thorough repair (‘DISM /Online /Cleanup-Image /RestoreHealth’). These tools can help address underlying issues contributing to low memory on your PC.

Know The Answer of All Your Question

Here are some common questions about low memory issues on your PC and how Brilliant Tech can help you resolve them.

What causes low memory on a PC?

How can I check if my PC has low memory?

Will adding more RAM always fix low memory issues?

Is virtual memory the same as RAM?

No, virtual memory is not the same as RAM (Random Access Memory). RAM is physical hardware that your CPU uses for quick data access. Virtual memory, also known as the paging file, is a section of your hard drive that Windows uses to temporarily store data when your RAM is full. It acts as an overflow for RAM but is much slower than physical RAM. It can help prevent crashes but doesn't offer the same performance as actual RAM.

When should I call professional help for low memory problems?

If you've tried the common troubleshooting steps on how to fix low memory on PC and are still experiencing issues, or if you're uncomfortable performing these steps yourself, it's time to call professional help. Brilliant Tech offers expert remote support to diagnose complex memory issues, remove persistent malware, optimize system settings, and recommend hardware upgrades safely and efficiently.
