Hello everyone This is my first post, as well as my first build attempt, so please be gentle. P4 3.0 ghz ASUS P4P800-VM 480w psu 1 stick MD4412UOE 512MB DDR-400 PC3200 Power Memory Integrated Intel Extreme Graphics I purchased all of my parts from newegg, and i finally found the proper time to put everything together. After getting a cpu fan that was too big, i purchased a AeroCool cpu fan. I had to remove the P4 retention module, and I now have the fan installed. I installed everything else (cd-rom, hdd, disk drive), and I turn the power on, to find that nothing is happening. I have taken the mobo out of the case to make sure it isnt grounded, and none of the fans power up. The only indication of power I get is the green stand-by light located between the second and third pci slots, and the keyboard lights flash on, then off. Whenever I turn the power switch on, the same thing happens with the keyboard and the rest of the mobo. I have a buddy who is also putting together his own build, and he said that it was strange to hear that not even the psu fan is starting up. The psu has two power receptables, that I can best describe as female and male. Dont know if this makes any difference. I dont know what to do, and I was wondering if this sounds even remotely familiar to anyone. Am I missing something with some of the jumper settings, or does it sound like a huge problem? Thanks again in advance for any help, and I'm glad I found my way to this place.
