Check the computer’s hard drive / SSD for errorsīefore performing a hard drive check, you’ll need to determine which type of drive you have. You may need to replace the RAM module(s) in your computer to avoid system instability and freezing. This is often caused by wear and tear over time. It appears that there are physical defects with the RAM hardware module(s) in your computer. This will test most of your memory (leaving enough for the system to operate) for 3 cycles and will report back any errors it finds. Replace the # character with the value you determined in step 4. Run the memory test by entering the following command in the Terminal.

Open the Zorin Menu → Utilities → Terminal.Įnter the following 2 commands into the Terminal to install the memory test software: sudo apt update Once you know the total amount of memory, round up to the nearest whole number, then subtract 4.

You will need to determine how much memory / RAM your computer has before running the memory test. View how to activate NVIDIA graphics drivers › Run a memory test

If your computer has an NVIDIA graphics card, installing its official driver software may resolve the freezing issues.

If this didn’t resolve the issue, please continue following the steps below.

Restart your computer to apply the changes.

Open the Zorin Menu → System Tools → Software Updater.

Oftentimes, newer hardware drivers or other system-level software are already available to resolve freezing issues on many computers. To find the source of the issue and resolve it, please follow these instructions: Install software updates
