Hello Whilst swapping over my case to another I accidentally caught and pulled off, with my video card, a yellow jumper that is connected to two of three pins and is between the PWR Fan header and the USB block, near the AGP port - just above it and to the left. I have downloaded the latest manual but that doesn't help me any more than the printed one so can anyone help me to know where this jumper is positioned on the pins...? Knowing what it does might be useful as well :) Thanks for your help Morgan
