So the motherboard was an Intel S1200BTLR a very shotty board that i would not recommend to anyone. we had problems from day one. anyway. so i am doing a standard memory upgrade everything seems normal and fine pop in the new memory boot up bsod. then nothing. unbootable. it just sit's forever trying to boot. so i try the normal crap... DSR Safemode SysR chkdsk found and fixed a bunch of bleep but still unbootable.
So now i'm all freaking out thinking i'm going to be spending the whole weekend restoring the domain and i'm not happy about it. so out of desperation i throw in a S1200V3RP and the damn thing boots. domain intact... dns users i was amazed and compleatly relieved... So if anyone can give me a clue as to what the hell happened that would be swell.
I have since reloaded the BTLR and it is running just fine... I'm well confused by this turn of events and it's not a hell of a big deal at this point since everything is working but damn...what a day.
