The keyboard is active through pressing F8, but does not move the selection bar up and down on the screen where one chooses SafeMode etc.
I can enter setup with F12 and can move up and down in the setup menu with arrow keys, but am locked up immediately on closing.
If I let Startup run its course with no keyboard intervention I get the Windows logon screen, but the PC is locked up. Cannot type in the password field, Ctrl-Alt-Del does nothing, no lights go on or off when toggle CapsLock or NumLock.
If I boot with a Linux disk I get a desktop, but keyboard is again nonresponsive.
Nothing works but power button.
Any suggestions where to start?
