I recently built a computer from the ground up using a mix of new and used parts. After doing my research and getting everything assembled I'm having a problem getting the computer to boot.
I power up the computer and one of three things happen. (1) The system and CPU fans start to run and then after about 3 seconds, the power shuts down. (2) The system and CPU fans start to run the speaker emits one short beep and the power shuts down. (3) The system and CPU fans start to run the speaker emits one short beep, the monitor wakes up and then the power shuts down.
In any case there is no apparent drive activity and no on-screen messages. Here is my configuration:

ATI Xpert '98 8MB AGP Video Card - new component
