Newly built comp turns on for about 3 seconds then restarts

[EShink]

Hello, the problem I am having is really getting on my nerves. When the power button is pressed, the comp turns on for about 4 seconds than turns off (no beeps coming from mobo). After it shuts off it turns on indefinitely with no display. Any ideas what might be causing the problem?

What motherboard are you running and what is the rest of your setup?
