the error code is quite explicit,

replace the failing menory module in socket 7 on cpu 0

if you want to make sure it's the module and not a hardware issue such as a bad socket contact, simply swap the module in memory socket 7 with another same sized module from another memory socket

the error msg should now change to the location you put the suspect memory module in
