I am building a new computer for myself (I have built them in the past). I have a motherboard, CPU, video card, sound card, DVD writer, CDRW drive, hard drive, 3.5" disk drive, 2 GHz memory and a 300 watt P/S (which said it was P4 approved). When I go to turn the computer on, there is a green light that comes on the motherboard and a green light behind the computer's power switch, but nothing else works. No hard drive spinning, no CD drives, making any boot up noise, etc. I thought it was the power supply, so I ordered another of the same case. The same problem happens with this new case. Any suggestions?

A place to start:
System designs based on Pentium 4 processors will require ATX12V power supply. The extra +12V power connector enables the delivery of more current to the Pentium 4 processor. The presence of the +12V 4-pin connector indicates that the power supply is an ATX12V. The absence of the +12V 4-pin connector indicates that the power supply is not compatible.
is the 4 pin connector connected?
Otherwise start with only the power supply, motherboard and cpu..... does it come up?
If so, start adding components one at a time, booting each time to isolate the bad part.
