A memory module (RAM) might cause instability of your system with repeated crashes: blue screen, computer crashes during use, IRQ NOT LESS errors, data loss, etc… This is a very sensitive component of of your computer, and you should definitely take care of it if something goes wrong with your computer. With Windows 7, Microsoft has introduced a variety of memory diagnostic tools. They will allow you to accurately analyze your memory cards by making them do transactions, calculations, and the heavy demands.
Launch diagnostic tools of memory
If the memory diagnostic tools do not work under Windows, you can launch them from the search
Step 1: Close all documents and software you’re using.
Step 2: Click the Start button.
Step 3: In the search box, type memory.
Step 4: Click the Windows Memory Diagnostic program that appears at the top of the list.
Step 5: Click the Restart now and check for problems.
Step 6: Your computer is then restarted and then analyzed your submission.
Enable improved tests
By default, diagnostic tools perform ten tests. You can improve the analysis of your memory by doing instead of twenty tests. The operation takes longer, but more relevant.
Step 1: Press F1 for options.
Step 2: Using the arrow keys, select Extended Test.
Step 3: Press the Tab key on your keyboard to switch to the cache. Select the Active option.
Step 4: Press again the Tab key on your keyboard. Attach the number of passes, that is to say the number of times tests will be repeated to 5.
Step 5: Then press the F10 key to apply your settings.
Step 6: Wait until the check (this may take about thirty minutes). You do not have to sit at your PC, you can check the results later. Your computer is then restarted.
Analyze the results
On the next Windows 7 start, the test results are normally displayed as a small bubble in the notification bar. If you do not have time to see where if the bubble does not appear, you can consult in the event viewer of Windows.
