After building the computer up, everythings plugged in correctly and stuff. I have a centurion 5 q6600, ballistix 2x1gb ram at ddr2-800, an oczgamexstream 600 watt power supply, and a p35 ds3p motherboard, with no led light to show that its working.

i pushed the power button, the computer and power supply nworks for 1 second, then shuts off......any ideas? since it turned on, that means its not the case connectors, correct? really desperate for help.......cant find any on other forums......

Hi Coldness, and welcome to BleepingComputer.

Did you use thermal compound to the surface of the CPU heat spreader before installing the heat sink and fan?

Did you recheck to make sure that all of the components are properly seated, all of you cable connections are tight?

Is your RAM properly populated?

Did you connect the P4 connector from the PSU to the motherboard for the CPU?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

yes, i have done all that. it has just flashed on for 1 second, then turned off again. could it be a faulty power supply? or is it being shhorted? my motherboard is on the standoffs...

also, does the wires touching the case ause shorts as well, or is that negligent?

I would try it on the bench with a piece of cardboard underneath, just to be sure it's not grounding out of the frame some place. On my builds, I use insulated washers between the board and stand-offs. Start with just the mobo memory and hard drive and continue to add things as you go along
