I have my new business build. After a few trys I seem to have it running. During my set I did experience what I can only call no power. Sometimes when I would hit the power button I could see the fans starting and then everything just stopped .It happened a number of times. After I unplugged everything including the power pin on the mobo it would start again. It is now running overnight at work and I'll see what it looks like in the morning. I am worried there is a short or something and I don't want to put it in use until it is stable. All parts are new. xp pro os Foxconn mobo, lga774 3.0 cedar mill , 2gig memory, 2 hitachi hd sata, Antec 500 earth power 1 standard dvd rw. Fan in rear and front 120mm. What does it sound like to you? ps 1 hd has os the #2 just for backup The cosmos shows both as masters on different channels. Should 1 be a slave?
