How do I run a diagnostic test on my system memory?

A system memory test can require two or more hours to complete, so we recommend running it overnight, or while you're away from your computer. If there is a faulty stick of RAM in your PC it could cause issues ranging from memory management errors to system crashes and blue screens (BSODs). Please follow the steps below to run a memory diagnostic test through Windows. Once the test is finished the system will boot back in to Windows.

1. Type Mdsched.exe or Windows Memory Diagnostics in the Windows Start menu search bar.

2. You can either choose to restart now to start the test immediately or “check for problems the next time I start my computer” to test the system the next time it boots up.
