If you are encountering the “Error 111 Insufficient Memory” message on your Windows 11 PC, it means your system is running low on available memory resources. This can cause programs to crash or slow down, making your computer difficult to use.
Fortunately, there are several simple steps you can take to fix this issue. Most solutions involve freeing up memory or adjusting system settings to better manage available resources.
This article will guide you through easy-to-follow methods to resolve the Error 111 problem and improve your computer’s performance.
Let’s get started by understanding some quick checks before diving into the troubleshooting steps.
Quick Note: Prerequisites and Initial Checks
- Restart your computer: A simple reboot can clear temporary files and reset memory usage.
- Close unnecessary programs: Running too many apps simultaneously uses a lot of memory.
- Check your available RAM: Click Start > Settings > System > About to see installed RAM. If it is very low (e.g., 4GB or less), consider upgrading.
- Ensure Windows 11 is updated: Go to Settings > Windows Update and install any pending updates.
Step 1: Close Background Apps to Free Memory
Background apps consume memory even if you are not actively using them. Closing these can help fix the insufficient memory error.
- Right-click the Start button and select Task Manager.
- In the Task Manager window, click the Processes tab.
- Look for apps using high memory under the Memory column.
- Select any unnecessary apps and click End Task at the bottom right.
Why this step is important: Closing unused apps reduces memory load, allowing more resources for the programs you want to use.
Step 2: Increase Virtual Memory (Paging File)
Windows uses virtual memory as extra RAM by using space on your hard drive. Increasing this can help when physical RAM is insufficient.
- Press Win + S, type Advanced system settings and open it.
- In the System Properties window, under the Advanced tab, click Settings in the Performance section.
- Switch to the Advanced tab and click Change under Virtual Memory.
- Uncheck Automatically manage paging file size for all drives.
- Select your system drive (usually C:), then choose Custom size.
- Set the Initial size and Maximum size to values higher than your current RAM size (for example, if you have 8GB RAM, set 12288 MB for both).
- Click Set, then OK, and restart your PC.
Why this step is important: Increasing virtual memory gives your system more breathing room to handle memory demands without crashing.
Step 3: Disable Startup Programs
Some programs automatically start with Windows and consume memory unnecessarily. Disabling them can improve overall system memory availability.
- Right-click the Start button and select Task Manager.
- Go to the Startup tab.
- Review the list and disable programs you don’t need to start automatically by selecting them and clicking Disable.
Why this step is important: Reducing startup programs frees memory immediately after boot, making your system faster and more stable.
Step 4: Run Windows Memory Diagnostic
Sometimes, memory issues are caused by faulty RAM modules. Running a memory test can identify potential hardware problems.
- Press Win + S, type Windows Memory Diagnostic, and open it.
- Choose Restart now and check for problems.
- Your computer will reboot and run the test. Wait for it to finish and check the results.
Why this step is important: Detecting defective RAM early can prevent ongoing errors and help decide if hardware replacement is needed.
Step 5: Scan for Malware
Malware can consume system resources without your knowledge, leading to memory errors.
- Open Windows Security by typing it in the Start menu search.
- Go to Virus & threat protection and click Quick scan.
- If threats are detected, follow the prompts to remove them.
Why this step is important: Removing malware helps restore normal system operation and frees up memory resources.
Alternative Methods and Advanced Options
- Upgrade your RAM: If your system consistently runs low on memory, physically adding more RAM is the best long-term solution.
- Use ReadyBoost: If you have a USB flash drive, you can enable ReadyBoost to use it as additional memory cache. Right-click the USB drive in File Explorer, select Properties, go to ReadyBoost tab, and follow instructions.
- Adjust Visual Effects: Go to System Properties > Performance Options > Visual Effects and select Adjust for best performance to reduce memory use by Windows animations.
Frequently Asked Questions (FAQs)
What causes Error 111 Insufficient Memory on Windows 11?
This error usually occurs when your computer runs out of available RAM or virtual memory, often due to too many apps running, memory leaks, or insufficient physical memory.
Can I ignore this error temporarily?
While you might be able to continue working for a short time, ignoring the error can lead to crashes or data loss. It’s best to address it promptly.
Does increasing virtual memory slow down my PC?
Virtual memory uses your hard drive, which is slower than RAM. Increasing it helps avoid crashes but may reduce performance slightly if heavily used.
Is it safe to disable startup programs?
Yes, but only disable programs you recognize and do not need immediately after startup, such as unnecessary utilities or apps.
How do I know if my RAM is faulty?
Running the Windows Memory Diagnostic tool will help detect hardware problems that might cause memory errors.
When Nothing Works
If you have tried all the above solutions and still face the Error 111 Insufficient Memory problem, consider the following final options:
- Contact Microsoft Support: Visit the official Microsoft Support website for professional help.
- Restore Windows 11: Use Settings > System > Recovery to reset your PC without losing personal files.
- Consult a professional technician: Hardware issues like failing RAM or hard drive problems may require expert diagnosis.
Conclusion
Fixing the Error 111 Insufficient Memory on Windows 11 involves freeing up system memory, adjusting virtual memory settings, and checking for hardware or malware issues. Starting with simple steps like closing background apps and increasing virtual memory can often resolve the problem.
For persistent issues, running diagnostic tools and considering hardware upgrades may be necessary. By following this step-by-step guide, you can improve your PC’s stability and enjoy a smoother Windows 11 experience.
