I just put my new build together and I have ran into a problem. I plugged all my case fans into the motherboard fan headers. I plugged my power supply into the "pwr fan" header, it is a 4 pin going into a 3 pin header. When I press the power button the computer turns on but I get no video signal. I have the vga converter from dvi that came with my radeon 6950, not sure if that is an issue. Still besides video, I noticed that not one the 3 case fans are on/spinning. 2 are brand new with the case and one I just took out of my previous computer, it was working prior. The other thing I noticed that is wrong is I cannot hold the power button and turn it off. I have to turn it off via the power supply button. When I was hooking up the front panel buttons/lights the case connectors and the motherboard diagram were not exactly identical. The video card, cpu heatsink fan and psu fans all work.
I find it odd that I don't get a video signal and also do not get power to case fans, makes me think that the motherboard is faulty. I am hoping I have something plugged in wrong could cause all 3 fans to not work plugged into 3 separate headers. I don't have an internal speaker to listen for post, or error beeps. Anyone that has had a similar experience with case fans not working and video simultaneously? That is the only thing that makes me think it could be me, because its not just one thing. Should I reseat the cpu/heatsink? Could that even cause things like this?
