Memory Diagnostics Tool

How to Run the Memory Diagnostics Tool in Windows 7

   Information
This will show you how to run the Windows Memory Diagnostic Tool to test the Random Access Memory (RAM) on your computer for errors in Windows 7. The diagnostic includes a comprehensive set of memory tests. If you are experiencing problems while running Windows, you can use the diagnostic to determine whether the problems are caused by failing hardware, such as RAM or the memory system of your motherboard.

For more information, see: Microsoft Online Crash Analysis: Windows Memory Diagnostic Users Guide

   Tip
If you suspect memory issues, then you may also want to consider using and running Memtest86+ at boot. Memtest86+ is a comprehensive stand-alone memory diagnostic program that you boot from at startup to test your RAM. You can download a ISO file to burn to DVD to boot with, or a floppy disk package installable from Windows to a USB flash drive or floppy disk to boot with.

   Warning
It could take a long time (several hours) for the Memory Diagnostics Tool to finish running depending on how many passes you set, and if there are any issues found.





Here's How:
NOTE: Start with either step 1, 2, or 3 for how you want to start the Memory Diagnostics Tool. 1. To Start from within Windows 7 A) Open the Control Panel (icons view).

B) Click on the Administrative Tools icon, and click on Memory Diagnostics Tool.

C) Go to step 1F below.

OR

D) Open the Start menu.

E) In the Start Menu search box, type mdsched and press Enter. (See screenshot below) Start-Menu.jpg
F) Select the Restart now and check for problems option. (See screenshot below) Memory.jpg
G) Go to step 4.
2. To Start from Windows Boot Manager A) Boot into the Advanced Boot Options screen.

B) While in the Advanced Boot Options screen, press the Escape (Esc) key. (See screenshot below) Advanced-1.jpg
C) While in the Windows Boot Manager screen, press the Tab key. (See screenshot below) Advanced-2.jpg
D) With Windows Memory Diagnostics selected, press Enter. (See screenshot below) Advanced-3.jpg
E) Go to step 4.
3. To Start from System Recovery Options A) Boot into the System Recovery Options screen.

B) Select the Windows Memory Diagnostic Tool option. (See screenshot below) System_Recovery_Options.jpg
C) Select the Restart now and check for problems option. (See screenshot below) Select_When.jpg
4. The computer will now restart, and you will see this screen next. (See screenshot below.
NOTE: Windows Memory Diagnostic Tool will run the Standard test by default. 1.jpg

A) Go to step 6.
5. To Change the Memory Diagnostic Tool Options A) Press F1. (See screenshot above)
NOTE: If you have a multimedia keyboard, then you may need to press the Function (F-Lock) key for F1 to work.

B) Press the TAB key to switch between the option categories, and use the arrow keys to select the option. (See screenshot below) Options.jpg
C) When finished, press F10 to apply any changes you made to the options. (See screenshot above)
NOTE: Press the Escape (Esc) key if you do not wish to make any changes to the options and return to the screen below step 4.
6. When the test is finished running, it will automatically restart the computer. (See screenshot below step 4)
NOTE: If errors are found, the Windows Memory Diagnostics Tool will attempt to determine which particular memory module in your computer is causing these errors. If that information is available, it will be stated in the results after you log on from the restart. If bad memory is found then you will need to remove and replace the bad RAM module.

7. You can also read the Memory Diagnostic Tool system log in Event Viewer.
That's it,
Shawn

Sorry HammerHead, but this is running at boot before Windows 7 starts. You would not have the Task Manager as an option. Only after Windows 7 starts up you would. :)

Did you hit it a second time,

after the first 'Esc' stopped the 'scan-in-progress'?

Did you have computer power 'on' when you yanked the memory boards?

Certainly, with mainframe power off, the box is ready to boot from anywhere,
when power is reapplied...

No the system was powered off and power switch on the back was off also.
Hitting the esc button only paused the scan it did not stop it . i rebooted several times and memory tool still started every time. when i powered off and power switch on the back was off. I removed the ram and restarted my system it still went to memory tool but esc worked this time and rebooted and system came up. Also before running this tool due to a system crash action center told me to run this action and it did fix a problem i had with ATA channel 0 and channel 1the both had a yellow
warningicon.png
beside them and now gone after this happened.

when i powered off and power switch on the back was off.

I removed the ram
and restarted my system it still went to memory tool
but esc worked this time and rebooted and system came up.
What I have observed with my trial, is that a single Esc paused the testing.
It took a second keystroke to actually Exit.
I read your post as:

1. No, I did not hit 'Esc' a second time during initial memory test.

2. Memory testing started immediately, after every subsequent reboot.
(Did you ever hit 'Esc' key twice during these Memtests? Or just once?)

3. Finally, after several reboots, the ram was removed.

4. After ram removal, a single 'Esc' key exited the Memory Test utility and booted the w7 operating system.

5. You are currently running w7 with some ram still removed. 2 modules or 1?

The implication is that the removed ram is 'suspected bad' ram.
i.e. the single 1, or one of the 2, or both of the 2.

The next step would be to temporarily swap the installed ram with the suspect ram (but only 1 module at a time),
and run Memory tests again, restarting at square 1.
Keep the 'good ram' separate from the 'suspect bad' module.

(What happened prior to 'Memory testing' is of no concern here.)
(We're only 'looking at' the Memory test utility and the hw ram modules.)

More then twice

3. Finally, after several reboots, the ram was removed.

4. After ram removal, a Double 'Esc' key exited the Memory Test utility and booted the Windows 7 operating system.

5. You are currently running Windows 7 with some ram still removed
No reinstalled both sticks 2gb each 1066mhz OCZ.

Hello Hector, and welcome to Seven Forums.

Normally if you did not have a pop-up, it did not find a problem. You might consider running Memtest86+ to help test and verify your memory further.

Hope this helps,
Shawn

Until whenever it finishes. It may be best to start it before you head off to bed and let it run overnight though.

Where is the log file

Hi,

Do you know where the log file is located? I'd like to review it. (I mistrust the "usually means no problems". What about "unusually"...)

Thanks

Eric
