Diagnose Computer Memory

A bad RAM memory stick, can cause many problems on your computer such as blue screens, crashes, disk read errors due to file corruptions, etc. Testing Memory for errors, is a necessary action to ensure your computer's stability if you have installed a newly RAM Module on your system, or if you suspect that you may have a problem with your existing RAM.
