Computer Shuts Down during Boot

I just bought some new pieces to build a new computer. Hadn't done so in a while. My problem though is that the computer is shutting down after POST every single time. This happens whether I am trying to install the OS or just load an existing OS. It will spend about 5 - 10 seconds then simply shut down. There are no flashes of BSOD, beeps, or warnings, just off.

I have unplugged everything but the hard drive (Tested this in another machine and its fine), 1 stick of RAM, video card, and CPU.

The components are as follows:



Motherboard -

Power Supply -

I'm not sure if this is a result of bad CPU or Motherboard. I tested the PSU on another working machine and it passed the test. I don't think the RAM is the problem since I don't get any hiccups or error messages. I unfortunately do not have another Intel compatible motherboard to try the CPU on.

I can sit in the BIOS all day long. CPU temp never exceeds 30c.

Any thoughts as to which piece might be the culprit here?

Thanks in advance!

  1. Please note that I have reset the CMOS and selected the lowest BIOS settings to make sure that there were no bad voltage or frequency settings.
  2. Can you go in BIOS? Check the Temp of you CPU. May be the Heat-Sink is not correctly installed? It's a protection to avoid melting your CPU.
  3. As mentioned, I can get into the BIOS and the CPU temp stays below 30c
  4. No other ideas?
