Well, this one will be a tough one I think. Recently I decided to put the guts of my comp into a new case so that I could get more airflow using filters so that I would not have to clean the entire board every six months when it was full of dust and stuff. So, I transfered the motherboard (D865PERL) into the new case and printed out the entire product description and technical reference pages and read them all. Then I proceeded to hook up all the connections which I might say I think I did a pretty good job of, however, there is one connection I can't find and I believe it to be the reason my comp syas cable not connected when I start up. Incidently, when it starts, it shows the nvidia screen and RAM and then goes into a screen that says the comp did not shut down properly and askes if I want to start windows normally or in safe mode. No matter what I click on it eventually goes to a black screen and a little blue square pops up that says cable not connected. If I leave it alone it will just restart itself and go through the same motions. That said, The only loose cable I have appears to be a thermal sensor cable that is glued to the copper underside of the heat sink. It is a black wire, actually two black wires together, with a white two hole end and for the life of me I cannot remember what that was connected to. I have an intrusion plug open, two fan plugs open and the IEEE bus pins open, but the wire does not reach any of these and there is nothing open that I can put a connector on near the CPU. The CPU fan is in the right place and I believe I put the front panel wires where they belong according to the reference tables and images and I just can't figure out why it won't work. Now when I had it off I did add a TV tuner on one of the PCI slots, but everything else is good to go. I am hoping someone can tell me what to do either with the thermal wire or in getting this comp to boot and run. Thanks for any help in advance.
