I basically wanted to test everything out today and start by installing windows and all the drivers (touchscreen, mobo, gps) but the 2-pin jumper cable that goes from G at JP1 from the PSU to the Power on header on the mobo is acting very stupid. when i have it pluged in properly (yes i checked polarity) it totally ignores the ignition switch and i have to manually take it out and give it that start by plugging it in. so the PSU jumper cable is acting like its pushing the button in for a force shutdown. what should i do. as far as cabling goes i checked everything as well as my uncle.
thank for all advice
