Data cable cancel power from Motherboard to IDE components
Posted on 2006-06-25
I am rebuilding a P4 generic system, simply the data strip when connected to hard drive or cd rom or any IDE equipment cancels the power to that component (ie: when i connect the power wires to the hard drive it runs with out a problem, then if i connect both the data cable with the power wire the hard drive will not run it loses the power, now the second i pull the data cable out the hard drive starts up.) i swapped out the mother board thinking there was a problem on the existing board,, results SAME, i pulled and swapped the power supply,, result SAME. process of elimination,, pulled sound card,, SAME, pulled graphics card,, SAME, pulled mem module,, SAME, pulled CPU,, SAME,,, i pulled all the wires from the board SAME on every instance. ergo,,, HELP!!!! any ideas please the customer is slamming my cell phone, i am at the end of ideas only thing left is the case it self, could this be some kind of ground problem?? i am hoping one of you has run up against this before and has an answer....
Also is there a web site where i can obtain motherboard info like jumper settings etc. or onboard peripheral drivers.
