I understand this is a hardware error, but since the system runs fine in safe mode (with networking) i am not sure where to begin in troubleshooting.
The only thing that jumps out at me is that the memory is not listed on the asus list of compatible memory types for this mother board (i have tried re-seating the sticks). However we have two of these exact same machines and the other does not seem to have any issues, so should i not worry about the compatibility?
on the new z77 mb asus has a lot of bios fixes for cpu code and ram..have you check that your mb bios is up to date.
on the asus bios also make sure you have xmp profile turned on to get the max speed from your ram sticks. also if you clicked the overclock button in the easy bios setting it switching the ram bus timing from 1:1 to 1:5 some ram and asus mb dont work right with the 1:5 speed timing.
