Ok, I just mounted an Iwill P4s, put a P4 1.7 in, then put my 3 sdram dimms in, then connected a graphics card, I also hooked up the HDDs and the power just to see if I could POST it. So when I turn it on, I hear the HDDs spin up and start to click..but then no video and I get that typical siren sound from the PC speaker.. any ideas what could be wrong? I checked the seating on the RAM and it's all seated fine.
