I am trying to build a pc from a motherboard and intel processor that I bought awhile back through the Intel Retail's Edge Program. I put the motherboard (Intel® Desktop Board DG965WH ) and the processor in (Intel® Core™ 2 Duo Processor E6300) in to the case (which I also bought new.) After troubleshooting different problems, I finally got the (heatsink fan) to turn on.However, it seemed that there was no video signal going to the monitor (I have a separate video card, but I was using the built-in VGA output.) and now...sometimes, when I turn it on, the heatsink fan turns on for a couple of seconds and then the fan shuts off. any ideas on what it might be?
