by

Low memory warnings can bring your PC to a frustrating halt, but several straightforward solutions exist. If you’re wondering how to fix low memory on pc, you’re in the right place. This guide provides clear, actionable steps to free up your computer’s RAM and stop those annoying alerts for good.

How To Fix Low Memory On Pc

Fixing low memory involves a combination of short-term actions and long-term adjustments. We’ll start with the quickest fixes you can do right now and move to more advanced solutions. Follow these steps in order for the best results.

Restart Your Computer

This is the simplest and often most effective first step. A restart clears your system’s RAM, shutting down all processes and applications that have accumulated over time. Many background tasks can start and never properly close, consuming memory without you realizing it.

  • Save any open work.
  • Click the Start menu and select “Restart.”
  • Allow your PC to fully boot up again.

Check if the low memory warning returns after the restart. If it does, proceed to the next steps.

Close Unnecessary Programs And Browser Tabs

Every open program and browser tab uses RAM. Modern web browsers, in particular, are notorious memory hogs. Having dozens of tabs open can easily consume several gigabytes by itself.

  1. Look at your taskbar and system tray for open applications.
  2. Right-click each program you don’t immediately need and select “Close.”
  3. Open your browser and close tabs you are not actively using. Consider bookmarking pages for later instead of keeping them open.
  4. Use your browser’s task manager (like Chrome’s Shift+Esc shortcut) to see which tabs or extensions are using the most memory.

Check Memory Usage With Task Manager

Windows Task Manager is your primary tool for diagnosing memory problems. It shows exactly what is using your RAM.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click on the “Memory” column header to sort processes from highest to lowest usage.
  3. Look for any unfamiliar processes or applications using an unusually high amount of memory.
  4. If you see a non-essential program using a lot of RAM, select it and click “End task.”

Pay attention to the “Memory composition” graphs at the top for a broader view of how your RAM is allocated.

Identifying High-Memory Processes

Some processes are essential for Windows. Do not end tasks for system processes like “Windows Explorer” or “Client Server Runtime Process.” Focus on applications you recognize, like web browsers, video editors, or games. A process using hundreds of MB or multiple GB when idle is a prime candidate for closure.

Disable Startup Programs

Programs that launch automatically when Windows starts run in the background, consuming memory from the moment you turn on your PC. Disabling ones you don’t need can free up significant resources.

  1. Open Task Manager (Ctrl + Shift + Esc).
  2. Go to the “Startup” tab.
  3. You’ll see a list of programs and their “Startup impact.”
  4. Right-click on any non-critical program and select “Disable.”

Focus on disabling things like cloud storage installers, chat apps, or media helpers that you don’t use daily. You can always start them manually when needed.

Adjust For Best Performance

Windows has visual effects that make the interface look nice but use system resources. Toning these down can free up a small but useful amount of RAM and processing power.

  1. Type “Performance” in the Windows search bar and select “Adjust the appearance and performance of Windows.”
  2. In the Visual Effects tab, select “Adjust for best performance.” This will disable all animations.
  3. Alternatively, choose “Custom” and manually uncheck effects like “Animate windows when minimizing and maximizing” or “Fade or slide menus into view.”
  4. Click “Apply” and then “OK.”

Run A Virus And Malware Scan

Malicious software like viruses, trojans, or crypto-miners can secretly consume huge amounts of your system’s memory. If your memory usage is high with no obvious cause, a scan is crucial.

  • Use Windows Security (Windows Defender) for a full scan.
  • Consider running a secondary scan with a reputable, on-demand malware removal tool.
  • Keep your antivirus software updated to catch the latest threats.

Removing any detected malware can immediately resolve unexplained high memory usage.

Increase Virtual Memory (Page File)

Virtual memory uses a portion of your hard drive to act as extra “RAM” when your physical RAM is full. While slower than real RAM, it can prevent crashes. Windows manages this automatically, but you can adjust it.

  1. Type “Advanced system settings” in the Windows search bar and open it.
  2. Under the “Advanced” tab, in the Performance section, click “Settings.”
  3. Go to the “Advanced” tab and click “Change…” under Virtual memory.
  4. Uncheck “Automatically manage paging file size for all drives.”
  5. Select your main drive (usually C:).
  6. Select “Custom size.”
  7. For Initial size (MB), enter a value 1.5 times your total RAM. If you have 8GB (8192MB), enter 12288.
  8. For Maximum size, enter a value up to 3 times your RAM. For 8GB, you could enter 24576.
  9. Click “Set,” then “OK,” and restart your computer.

Note: This uses disk space, so ensure you have enough free space on your drive.

Perform A Windows Memory Diagnostic

Sometimes, the problem is not software but failing physical RAM (memory modules). Windows has a built-in tool to check for hardware errors.

  1. Type “Windows Memory Diagnostic” in the search bar and open it.
  2. Choose “Restart now and check for problems.” Your PC will reboot.
  3. The tool will run tests during the reboot. It may take several minutes.
  4. After Windows restarts, check the Event Viewer for the results (the tool will usually show results on screen if errors are found).

If errors are detected, it strongly indicates a problem with your RAM sticks, which will likely require replacement.

Advanced Solutions For Persistent Low Memory

If the basic steps haven’t resolved the issue, these more involved solutions may be necessary.

Uninstall Unnecessary Software

Many programs install background services that run even when the main application is closed. Removing software you no longer use can eliminate these memory-hungry services.

  1. Go to Settings > Apps > Apps & features.
  2. Sort the list by size or installation date to find large or old programs.
  3. Click on any program you don’t need and select “Uninstall.”
  4. Follow the on-screen prompts. Some programs may require a restart.

Be careful not to uninstall system drivers or software you are unsure about. When in doubt, a quick web search can clarify a program’s purpose.

Update Your Device Drivers

Outdated or corrupt drivers, especially for critical components like your chipset or graphics card, can sometimes cause memory leaks or poor resource management.

  • Visit your PC manufacturer’s website (for laptops) or the websites of your motherboard and graphics card manufacturers.
  • Look for the “Support” or “Drivers” section.
  • Download and install the latest drivers for your specific model and Windows version.
  • You can also use Device Manager to check for driver updates, though manufacturer sites often have newer versions.

Perform A Clean Boot

A clean boot starts Windows with a minimal set of drivers and startup programs. This helps you identify if a background service is causing the memory issue.

  1. Type “System Configuration” in the search bar and open it (msconfig.exe).
  2. Go to the “Services” tab and check “Hide all Microsoft services.”
  3. Click “Disable all.”
  4. Go to the “Startup” tab and click “Open Task Manager.” Disable all startup items as described earlier.
  5. Close Task Manager, click “OK” in System Configuration, and restart.

If the memory problem is gone after the clean boot, you enabled services and startup items one by one to find the culprit.

Modify System Registry For Memory Management

Warning: Editing the Windows Registry is an advanced step. Incorrect changes can cause system instability. Always back up your registry first.

You can adjust how Windows clears system cache from memory. One tweak involves the “ClearPageFileAtShutdown” value, though its modern usefulness is debated.

  1. Type “regedit” in the search bar and run Registry Editor as administrator.
  2. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
  3. Look for a DWORD (32-bit) Value named “ClearPageFileAtShutdown.” If it doesn’t exist, right-click in the right pane, select New > DWORD (32-bit) Value, and name it.
  4. Double-click it and set the “Value data” to 1.
  5. Click OK and restart your computer.

This forces Windows to clear the page file on shutdown, which can slightly improve security but may slow the shutdown process. Its impact on active memory is minimal.

When To Consider Hardware Upgrades

If you’ve tried all software solutions and still face low memory warnings, your PC may simply need more RAM. This is common if you use demanding applications or have upgraded your software over the years.

How Much RAM Do You Really Need

  • 4GB: The absolute minimum for basic Windows operation. Prone to low memory issues with modern web browsing.
  • 8GB: The standard for general use. Suitable for office work, web browsing, and light multitasking.
  • 16GB: The recommended sweet spot for most users today. Excellent for multitasking, moderate photo/video editing, and gaming.
  • 32GB or more: For high-end gaming, professional video editing, 3D rendering, and heavy scientific/computational work.

How To Upgrade Your RAM

  1. Check Compatibility: Use a tool like CPU-Z to find your motherboard model and current RAM type (DDR3, DDR4, DDR5). Consult your motherboard or PC manual for supported speeds and maximum capacity.
  2. Purchase the Right RAM: Buy matching modules (a kit of two or four sticks) for the best performance in dual-channel mode.
  3. Install the RAM: Power down and unplug your PC. Open the case, ground yourself, locate the RAM slots, release the clips on the ends, align the notch on the new stick with the slot, and press firmly until the clips snap closed.

After installing new RAM, your system should automatically recognize it upon boot. You can verify the new amount in Task Manager or System Properties.

Preventative Habits To Avoid Future Low Memory Warnings

Adopting a few simple habits can keep your system running smoothly and prevent low memory problems from recurring.

Regular Maintenance Routine

  • Restart your PC at least once a week to clear temporary data from RAM.
  • Periodically review and clean up your startup programs.
  • Uninstall software you no longer use.
  • Keep Windows and your drivers updated.

Mindful Browser And App Usage

  • Use browser extensions that suspend inactive tabs to save memory.
  • Close desktop applications when you’re finished with them instead of minimizing.
  • Be aware that some applications, like certain antivirus suites or development tools, are inherently memory-intensive.

Monitor Your System

Keep an eye on your memory usage in Task Manager occasionally, especially after installing new software. This proactive approach helps you catch memory-hogging programs early.

Frequently Asked Questions

What Does It Mean When My PC Says Low On Memory?

It means your computer’s Random Access Memory (RAM) is nearly full. RAM is the fast, temporary workspace your PC uses for active tasks. When it runs out, Windows tries to use much slower virtual memory on your hard drive, causing severe slowdowns and potential crashes.

Can A Virus Cause Low Memory On My Computer?

Yes, absolutely. Certain types of malware, like crypto-miners or bots, are designed to consume as much of your system’s resources as possible, including RAM. If you see consistently high memory usage with no explainable cause, running a thorough malware scan is a critical step.

Is It Better To Increase Virtual Memory Or Buy More RAM?

Buying more physical RAM is almost always the superior solution. Virtual memory uses your hard drive or SSD, which is significantly slower than RAM. Adding more RAM provides a direct, fast performance boost, while increasing virtual memory mainly helps prevent crashes when RAM is exhausted.

How Do I Check My Available RAM In Windows?

You can check it quickly by pressing Ctrl + Shift + Esc to open Task Manager. Go to the “Performance” tab and click “Memory.” You will see a graph showing how much RAM is in use and how much is available. You can also see this information in Settings > System > About.

Why Is My Memory Usage High When Nothing Is Open?

Even with no user applications open, Windows runs many essential system processes and services. Antivirus software, update services, and hardware utilities all use RAM. However, if usage is extremely high (e.g., over 70-80% at idle), you likely have a background program, startup item, or potentially malware consuming resources, which the Task Manager can help identify.
