How to Perform a Memory Test

If you’re experiencing issues related to your computer memory, such as slow loading times or frozen software programs, perform a memory test. A memory test allows you to identify problems with the computer's random access memory (RAM), such as a defective RAM chip. Many computer systems come with a built-in memory tester that you can access at start-up. In other cases, you might find it advantageous to run a third-party tool.

Instructions
1. Reboot your computer to perform a basic memory test. The BIOS system, which loads at start-up, automatically performs a "memtest." If the computer beeps once, the memory is fine. If it emits a series of beeps, there may be a problem with your RAM. The memtest will display information about the problem so you can resolve it immediately.
2. Use the Memtest86 utility to perform a memory test . You can download the utility to your computer for free or purchase it on a disc (see Resources). The program is a standalone program that runs on any DOS, Unix or Windows operating system. This program does a diagnostic analysis of your RAM to determine whether there are current or potential issues for you to address. After running the check, you'll receive an error summary listing the problems, as well as troubleshooting tips to resolve the problems.
3. Scan your system with FreeRAM XP Pro to evaluate your computer's memory. This is another free utility that you can download to your computer (see Resources). The utility can work on Windows versions from the Windows 95 operating system to Windows XP. This utility checks the computer and also helps optimize the memory system when you set it on "AutoFree" mode. FreeRAM XP Pro helps free up memory to make your computer run faster. The utility also contains tools that monitor your PC memory.
