I'm trying to reformat and install Vista Home. I have the computers (Doing 2 Computers) set to boot from dvd rom, when the message hit any key to boot to disk the keyboard will not work. The same thing happens when booting to F8, keyboard will not work for those. Now I can hit delete key or F2 to enter Cmos and that works just fine. I have changed the keyboard 4 different times and they all do the same, (work to go to cmos but will not work to start the dvd to install Vista) this is happening on both of my computers. I have also changed vista disks and still no go. Hope some one can help with this problem.
