My old PC finally died completely Saturday. I've now got a new one set up. I installed a PNY GeForce 9600 GT in it. Every thing is running fine thus far, but after finishing I noticed a leftover packet that contained a small three-strand wire that is about 6 inches long and has connections on each end about the same size as HD jumpers. I can find no mention of this in the manual. What is it? And where should it have gone?
