Hi all, Weird problem; since this afternoon I cannot access my BIOS, BIOS boot device selection, keyboard is unresponsive before Vista boots. I use F11 to select a boot device, as one HD boots to Vista and a second one has XP on it. That way I don't use the MS bootloader... I use XP for gaming (because of non-existant support for SLI on nvidia's 7000-series) and Vista for general use. SATA HD for Vista is set as first boot device in BIOS, and now it's the only OS I can boot. I played GRAW this morning, so I know everything worked few hours ago. I did not touch BIOS settings, I didn't install any new hardware or software either. I also noticed that Windows boot menu (F8) doesn't respond to the keyboard either. I was trying to get into BIOS and resetted the pc while booting vista, so on next boot I got the 'safe mode'-menu; keyboard didn't work, however I'm using the very same keyboard now. I tried so far: *unplugging all the USB devices (as my keyboard is a wireless USB keyboard from Logitech) * unplugging everything except the keyboard and the screen * using an old PS/2 keyboard with all USB devices unplugged * shutting down, disconnecting the cable and switching the computer off with the switch on the back and waiting for 5 minutes Is there a way to fix this without clearing the CMOS? Pc is overclocked and runs fine, but don't rememeber the exact settings for PCI-e and CPU anymore. So clearing the CMOS means: a lot of work afterwards... thnx L.
