I have built a new computer with the exception on my grpahics and and optical drive. The computer boots and makes it through POST. It then shuts down at the windows 7 login screen or with in a few minutes after logging in. It does not BOSD or come up with any error, just shuts down. It does not turn on and off over and over again like alot of problems Ive read about.

As far as trouble shooting I have completed 22 of the 23 steps in the very wonderful guide http://www.tomshardware.com/forum/261145-31-perform-ste... . The only one I didn't complete was installing motherboard speaker to check beeps for errors. It was something I didn't think about ordering when I ordered my new set up. I've tried everything within my knowledge and skill level that I can think of and I am just lost at this point. If you need more specifics feel free to ask.
