Check the Amount of RAM Occupied

Before starting to resolve the issue, you must check the amount of RAM being used and the programs that are using memory. To do so, you can follow the steps provided below:

  1. Press Ctrl + Alt + Del.
  2. Click on Launch Task Manager, if it doesn’t open up directly.
  3. Click on More Details, and click on Memory to sort according to RAM use.

Now you can find the programs that are using a very high amount of RAM. If you find any suspect program or an unnecessary program, then you can simply click on End Task.

Scan Your System

In many instances, a virus, trojan horse, or malware may be consuming memory. If you don’t find any program using too much memory, then this may be the case.

You can use Windows security and several third-party software to easily scan your system. After the scan is complete, the security software will either delete the virus or quarantine the file.

Get Additional Memory

You may require additional memory to run QuickBooks on your system. If your system doesn’t meet the minimum requirements, then you’ll have to upgrade your system. Without a system upgrade, you won’t be able to run QuickBooks.

QuickBooks 2021 has the following system requirements:

  • Processor of more than 2.4GHz
  • RAM of more than 4 GB (8GB recommended)
  • Disk space of more than 2.5GB and additional space for company file
  • Windows 8 or above

Even though the minimum RAM required is 4 GB, it’s better to have a minimum of 8 GB of RAM.

Additional RAM may be required when:

  • Processing additional data
  • Creating reports
  • Launching tools
  • Working in multi-user mode
  • Using multiple instances of the software

While performing any of these, if QuickBooks has access to insufficient RAM, then it will crash. QuickBooks may also rely on third party software such as Microsoft Office, Adobe Acrobat Reader, etc. So if these programs start while you’re using QuickBooks, then additional RAM may be required.

This is where you need to make an investment. If you want additional features, want to use other software with QuickBooks, or simply want to process a lot of data, then you should upgrade the amount of RAM available in your system.

  • It won’t take too much time to install the update. When the updates are installed, you should restart your system.
  • Now check if the error is resolved.
  • If you’re working on a network, then you may find it easier to install updates by manually downloading them. By doing so, you can simultaneously install updates on all connected systems. And you can even install the updates on a server.
