Upon turning on my Area-51m R2 I it does a system check before proceeding to throw up an error code 511, provide a code to scan, and make a horrible beeping sound.

This happens every startup. I can press esc to proceed as normal for now but obviously something needs doing.

I've completed the two suggestions on the dell website:

     1. inspected the laptop for clogged or obstructed air vents - they are clean and unobstructed

     2. update the BIOS - BIOS is up to date.

What else can I do?
