Windows 7 is installed on my PC. When I try to boot from the Window 7 dvd, a prompt comes up saying "press any key..." but I press keys and no keyboard input is recognized. Windows goes ahead and boots from the hard disk. Also, when I hit the Reset button on the case to force a re-boot, a screen comes up saying Windows did not shut down properly last time (something like that) and giving different options to be selected by the arrow keys. Again, the keyboard is not recognized no matter what keys I press. This is a brand new system I just built. Everything is working great except for this issue. Is there some BIOS setting I need to change to fix this? Some other issue going on?
