Memory (RAM) can become corrupted and not work properly. Usually, a replacement is needed to fix the problem, but before you replace your hardware, you should use the Windows Memory Diagnostic tool. This tool is available in both Windows Vista and Seven.

Learn, in this guide, how to run the Windows Memory Diagnostic tool in Windows 7 or Vista.

    Thanks, I hope this one works, the previous ones I’ve tried (some using boot disks and others using linux) for some reason never seemed to work, they’d just get stuck and not show any progress. Maybe I was doing something wrong but I don’t think so.

      I jsut ran on win7 Pro, i thought the same thing, but after waiting about 1-4 mins, a little pop up will appear in the system tray, saying no memory errors were deteced, then drift away (like “windows has installed new updates”

    didnt help my computer any other ideas?

  • It all depends on what error messages you receive or symptoms you experience. Let us know in the forums and we'll help you out.

    ran the test, walked away, came back, windows was loaded, no report. so… is one required to sit and stare at the screen so not to miss a report during windows log on? where in the heck is my report?

    • I recommend trying again. The tool states: “Windows will restart your computer automatically. Test results will be displayed again after you log on.”

      same problem, even though I stayed and stared, I never saw the report….

  • Gianfranco

    On a Acer 4810TG I’m running the test from .. 9 hours and I arrived at 89% of the total.
    Is there a mistake or it takes such an incredible time to end ..  (still pending, No error reported until now).
    Thanks
