I just got done a 3 hour process of putting my brand new computer together piece by piece. I put on the defogger stuff using scothch tape and I know none of the lines where touching. I have all brand new parts and Ive checked and rechecked that everything is plugged in the right way. But still, all I can get it to do is turn on for a split second. The fans try to turn and then it goes off. It doesnt even do it everytime. Sometimes it wont do anything... then other times it'll flip on for a split second and try to spin the fans. I've found no pattern to when it will come on and when it wont. I have a Duron 950 and 300 W power supply trying to run a cdrw a 7200 rpm 60 gig hdd and only the fan on the thermaltake 7. I havent even got any case fans installed. Please help me. I'm so clueless as what to try next.
