It's rare but RAM modules can cause problems. Unfortunately, it's not always certain that
memory errors being reported by your system is actually due to problems with
RAM modules. Even worse is that an unstable system can be due to many problems including RAM failure.
Step 1: Back up all important files and data. You should be doing this on a regular basis anyway but if your computer is showing signs of failure don't wait any longer to perform this job.
Step 2: Start simple and analyze
problem.
* Have you added or replaced RAM? Is it installed properly? * Have you moved
computer? RAM modules can come loose. * Is it a new computer? RAM modules might not have been inserted properly. * Have you installed any new hardware upgrades? * Have you installed new software or might there be a virus problem? * Have you changed or installed patches for your operating system? * Do you have
correct RAM type? * Is
RAM module connectors tin or gold? * When your computer starts (boots) does it report
correct amount of RAM? * Does your system properties report
correct amount of RAM? * Are there any POST messages that indicate RAM problems? * Does
system report Parity errors or address failures whilst
system is running? * Do you get a Windows error message "exception error OE at>>0137:BFF9z5d0" or something similar? * You've tried everything else!!!
Any one of these can indicate a problem with
RAM module or something connected with it.
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. Only work inside
computer case when
power has been switched off and disconnected. Never open
power source.
Step 3: Start by reading through this article to establish some ideas about what
problem might be and how to resolve it. There is no absolute order for diagnosing problems it's equal parts science and magic. If it's hardware then you are probably going to have to open
computer case (steps 5 - 10 & 13). You may prefer to eliminate other problems first (steps 11-12). Or even run diagnostic software (step 14).
Step 4: Gather all
documentation that came with your computer, memory modules or MOBO (motherboard). You need information on make and model numbers, together with installation guides. If you are missing anything visit
PC or MOBO manufacturers web site. Most have excellent online documentation.
Step 5: Do you have
correct RAM? Check
MOBO or computer documentation for
type of memory module you should be using. Compare this with
memory module you have purchased. Look at
memory module; does
information on
module match with
sales invoice (have they sent you
correct product)? If you bought a name brand computer has
RAM purchased been tested on that particular computer? This can be an issue with Dell and other computers. You can check compatibility issues online through useful tools on www.kingston.com, www.crucial.com or
MOBO manufacturers own web site.
NOTE: Before
computer case is opened make sure that power is switched off and disconnected, press and hold
power button for 30 seconds to ensure residual power is lost and make sure that you are grounded to avoid damage due to static electricity. Use a grounding wrist strap or touch
metal case to discharge static electricity.
