Hello i have a quadra 630 case, with a 5400 mobo, 6360 ps, maxed ram, ati xclaim vid card. the thing powers up and stuff but shortly after boot up it just dies, like if somebody pulled the plug. i try again and sometimes it goes a bit further-like to the smily mac face-then eventually it dies too. wtf? mobo battery? the battery was taken from the original 630 mobo, so its not new..or could it be something else? help thanks./
