Hello everyone,
I have PowerEdge R910. During my usual shutdown, I can't start up my operating system again yesterday. At the BIOS screen, it displays a message like "The memory configuration is not optimal" but I have not touched hardware. If I plug USB drive which has a portable operating system, it works fine. Only built-in system doesn't work. Or if it gives me some errors related to an OS, I can search on the net.
Any kind of suggestion would very much appreciated.
Thank you for your help.
