This is a useful tool to troubleshoot PC freezing and crashes.
Suppose one of the PCs you support is acting up—freezing, crashing, blue screening. Is some piece of hardware failing? Is some newly installed application causing trouble? Or could it be faulty memory? One way to find out for sure is with the free Microsoft Windows Memory Diagnostic utility. This tool will run a variety of tests on your PC’s RAM to determine whether flaws exist in any of the modules. And, like all of the utilities presented in our Utility Spotlight column, it’s FREE!
