Hey guys longtime site user but new poster, just built a PC for my sister, my first build, nothing extravagant, sempron 2500+, 512 megs pc3200, fx 5200, etc, just a basic machine. I am having a problem with the mouse not shutting off after powering off the system. It is a microsoft optical mouse and it still glows after shutoff. I have a shuttle an35 ultra board and an antec slk 1650 case and power supply unit. What could be causing the mouse to stay on after shutdown? Thanks again guys!
