If Windows 7 or Vista detects a possible memory problem, you will receive a notification. Click the notification to open it.

If you wish to run this Windows Memory Diagnostics Tool on demand, open Control Panel and type ‘memory‘ in the search bar. Click on ‘Diagnose computer memory problems’ to open it. Alternatively, you can also type ‘mdsched‘ in start search and hit Enter to open it.

Choose between two options for when to run the Memory Diagnostics Tool.

If you choose to restart your computer and run the tool immediately, make sure that you save your work and close all of your running programs. The Memory Diagnostics Tool will run automatically when you restart Windows. It might take several minutes for the tool to finish checking your computer’s memory.

Once the test is completed, Windows will restart automatically. If the tool detects errors, you should contact your computer manufacturer for information about fixing them, since memory errors usually indicate a problem with the memory chips in your computer or other hardware problem.
