How To Verify Memory Using Windows

If your computer’s RAM (memory) is not error-free, anything on your computer can go wrong. You can’t trust it. Windows has a memory diagnostic program to test RAM built in to it. It’s very easy to use.

To run the Windows Memory Diagnostic Tool, there are two methods. One, select the Start button (just select the button on Windows 7 and 10, or on Windows 8,  select the Start button then choose Search from the pop up menu). Type “Windows Memory Diagnostic”. Two, press the Windows key in the lower left and then “R”.  A “Run” dialog box will open up. Type “mdsched.exe” into it and press Enter.

The Windows Memory Diagnostic app appears. To perform the test, your computer must reboot. To authorize this, select “Restart now and check for problems (recommended).” You can also select “Check for problems the next time I start my computer.” but I always choose the recommended option. If you have enough doubt about RAM to want to test it, there is no reason to wait.

The computer will restart and automatically launch the test. There is nothing more you need to do. It will report its progress, although there may be moments when nothing appears to be happening. When it’s finished, it will automatically reboot. Once you log back in, the test results will appear. Don’t worry if they don’t show up right away.
