When the need arises to check system RAM, try the Windows Memory Diagnostic tool that comes with Vista and Windows 7 — and is a free download for XP.
This app thoroughly exercises your system’s random-access memory, uncovering problems that can cause crashes, hangs, and other errors.
Every version of Windows, from XP onward, has shipped with professional-quality, system-management utilities, either built in or offered as free add-ons. These apps let you adjust and control many essential operating-system functions and features. Other tools, such as Windows Memory Diagnostic, help diagnose and troubleshoot system problems.
Part 1 of this series, “Accessing and understanding Administrative Tools,” gives an overview of all these tools and explains how to make them easily available from your Start menu.
Part 2 shows how to use Windows’ Performance Monitor to analyze and understand, in real time, a PC’s status as different programs run — or fail to run!
