I just made my first attempt at building my own computer yesterday and since then have not been able to get it to start up. I know everything is connected properly. I've tried getting it to start up outside of the chasis as well, but the same thing happens whether it's inside or out. Anyway, here's the problem. I currently have only the power supply, processor with heatsink and fan, one memory stick, and a video card connected to the motherboard and the chasis connection in their proper places. When I press the power button, the fans on the power supply, the processor and the graphics card spin for about five seconds, then everything shuts down. Then, without me touching anything, everything will start to spin again for 3-5 seconds and then shut down again. This process repeats itself until I turn the power source off. Any ideas? I've been searching online for at least four hours and have found similiar questions but nothing that really matches this. Thanks.
