I got a weird one for ya. I just formatted my hdd to install XP. It's my "secondary" computer and the monitor is quite old and not all resolution are supported so when it boot up the first time after installing, all I have is a blank screen. I use to go in safe mode, set the screen resolution than reboot and everything works.... But this time, when I tried to boot in safe mode, the moment XP started, my keyboard leds flashed than turned off. The "Welcome screen" of safe mode appear but I can't dismiss it because the keyboard and the mouse are not responding. For the record, I have what's most basic in keyboard and mouse model: ordinary keyboard with no special function and an oem logitech wheelmouse. Anything I can do?
