What to Do When Your Laptop’s RAM Is Full and Your Fans Are Loud


What could be causing the excessive RAM consumption on my laptop?

I have an 8GB RAM laptop that has been experiencing very high RAM usage (around 85%) for the past few weeks, even when I am not running any intensive applications. The task manager does not show any process that accounts for the high RAM usage, and the laptop’s fans are constantly spinning loudly. How can I diagnose and fix this issue?


RAM, or random access memory, is a vital component of any computer system. It allows the processor to access data and instructions quickly, without having to rely on the slower hard disk or solid state drive. However, sometimes RAM usage can become abnormally high, even when the user is not running any demanding applications. This can lead to performance issues, such as slow responsiveness, frequent crashes, and overheating.

There are several possible causes for high RAM usage on a laptop, such as:

  • Malware infection: Malicious software, such as viruses, spyware, or ransomware, can consume a lot of RAM and CPU resources, as well as compromise the security and privacy of the system. To check for malware, it is recommended to run a full scan with a reputable antivirus program, and remove any suspicious or unwanted programs or files.
  • Memory leak: A memory leak occurs when a program or process fails to release the RAM it has allocated, even after it is no longer needed. This can result in RAM being occupied by useless data, and prevent other programs from using it. To identify memory leaks, it is helpful to use a tool such as [Process Explorer](https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer), which can show the amount of RAM used by each process, and the type of memory (private, shared, or mapped). If a process is using an unusually high amount of RAM, it may be a sign of a memory leak. To fix memory leaks, it may be necessary to update or uninstall the problematic program, or contact the developer for a patch or a workaround.
  • Too many startup programs: Some programs are configured to run automatically when the system boots up, which can increase the RAM usage at startup and during normal operation. While some startup programs are essential for the system functionality, such as antivirus or drivers, others may be unnecessary or unwanted, such as adware or bloatware. To manage startup programs, it is possible to use the built-in Task Manager, or a third-party tool such as [Autoruns](https://docs.microsoft.com/en-us/sysinternals/downloads/autoruns), which can show the name, location, and description of each startup program, and allow the user to disable or delete them.
  • Insufficient RAM: Sometimes, the RAM usage may be high simply because the system does not have enough RAM to handle the workload. This can happen when the user runs multiple or resource-intensive applications, such as games, video editing, or web browsing with many tabs. In this case, the system may resort to using the hard disk or solid state drive as a virtual memory, which is much slower than RAM, and can cause performance degradation and disk wear. To check the amount of RAM installed and available, it is possible to use the built-in System Information tool, or a third-party tool such as [Speccy](https://www.ccleaner.com/speccy), which can also show the speed, type, and manufacturer of the RAM modules. If the RAM is insufficient, it may be advisable to upgrade or replace the RAM modules, or reduce the number or complexity of the applications running.
  • In

conclusion, high RAM usage on a laptop can have various causes, and can affect the system performance and stability. To diagnose and fix this issue, it is important to scan for malware, identify and resolve memory leaks, manage startup programs, and ensure adequate RAM capacity. By doing so, the user can optimize the RAM usage and improve the laptop’s performance.
