I don't know if this is a hardware problem or not but I can't use my camera or my printing machine and if I try the computer hangs on restart and turn off. I also tried to install a new spyware program and it installed but would not run. I than tried to restart and PC would not restart and Task Manager would not End Task on the new spyware. I have had to shut power off and than power back on to get computer back up. I am on Internet and Networking with router plus digital phone. I have no problem with the other programs on my computer and never had a problem with the camera or the printer. Any help in which direction I should go.
