Did you solve your problem? I have the same issue on z240 workstation.

Hello All,

This morning I experienced the same error on a 420z workstation. It had 1 4GB DIMM HP branded RAM installed. I updated the BIOS to the latest version, here is the link:

This didn't help much, but it did change the error screen which initially brought me here. I saw that nobody reall had the solution yet, so I got on the horn with HP, as the machine was still under warranty, she advised that I change the RAM. I pulled the 4GB stick out and replaced it with spares (HP branded), so far the issue is resolved. I am waiting for the warranty RAM to get here now. 

She said that along with the BIOS and MEMORY, a faulty video card might also be the issue. 

Hope this helps
