Re: Both optiplex gx620 computers beep and don't do motherboard checks

Memory modules are detected, but a memory failure has occurred.

• If you have one memory module installed, reinstall it and restart the computer.
  
• If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
• If available, install properly working memory of the same type into your computer.
• If the problem persists, contact Dell.
