Hi everyone, this is my first post here, so here goes nothing... I just built a new box w/ Antec 350W PSU, Athlon 64 X2 3800+, 2GB Corsair XMS Ram 800MHz, Stock Cooling, 250GB Sata Seagate, Biostar TForce 550 MB socket AM2, w/ GeForce 6200 Biostar graphics card. Yesterday, I assembled and hit the power switch and - nothing happened. About 2-3 min later, the machine magically came on. after that, it powered up and down normally, enough to get Windows vista installed. I then proceeded to box it up and take it to my wife's parents' home (I built it for them) and try to turn it on, and again - nothing. I figured maybe PSU, but put in a vantec 520w which has known to work, and still nothing. So Reseated everything on the board and still nothing. So I removed the board from the case and tried to power on outside of case and still nothing. There are no jumper settings that I can find that would have any effect on the board not booting, and I've tried using the case switch as well as the switch on the board. All that I can figure is that the board must be bad. If anyone has any advice or help to give, I gladly welcome it! Thanks!
