This has been a two part problem: My friend has a DP55WG but can't boot fully. The POST screen with the Intel logo comes up for a split second, the screen goes dark and then comes up again for a split second before moving onto the Windows loading screen. The loading screen comes up for a split second and then the system reboots. This will go on and on for as long as you let it without giving any error codes on the LED debug display. I took the entire system apart and tried it outside of the chassis to eliminate the possibility of a grounding issue. Now the board displays a 27 error code - "Initializing memory, such as ECC init" when even one stick is tried in any of the 4 slots. My guess is the board is pooched because it does the same with memory pulled out of my rig, which is 100% working. Any thoughts?
