I have put together a DG45FC for a HTPC and am having strange problems with it. The board acts very flaky, sometimes not starting up until 5-10 min later (fans run, post beep then nothing, does this over and over) other times it boots but the video is corrupt. Sometimes i get a code 51. And once and a while it works perfectly goes into Windows 7 no problem works great. I have already RMA'd the board once and the new one acts exactly the same. I am at a loss as to what to do?
I have tried different power supplies, different RAM, CPU's, bios, etc. They all do a version of the problems above. The event log shows ME initialization failed. Anyone have any ideas?
