Test out the RAM - Step 5

  • In your Filter Current Log window, you need to click on its drop-down menu located next to the “Event Sources.” Next, scroll down this menu until the “MemoryDiagnostics-Results” option is found. Check the box next to it & click on the “OK” option.

Test out the RAM - Step 6

  • Doing this will take you to your system’s Event Viewer. Here you would have 2 “Events” that are listed within the menu’s filter log. Click on each of these events & look at the information provided. In case you detect zero errors, opt for any other method. There is no problem with the RAM hardware. In case you do see the error, you have to continue ahead to the next step.

Test out the RAM - Step 7

  • The only right way to correct the RAM problem is to replace the RAM sticks. If preferred, you can opt to test each stick one by one. To do this, you need to shut down the system and remove other sticks except for the one being tested. You can then reboot the computer & rerun all the steps starting from 1 to 7 in this list.

Repeat this using all the RAM sticks one after another. You can replace any sticks that have factory errors. Check whether your Steam issue has been corrected after replacing the same.


Once you have tried out all these solutions explained above, your Steam client should be back to normal. However, if none worked for you, it could be a problem with the main Steam program.
