I have windows 7 64 bit with Asus p8z68-v le motherboard. The ctrl+alt+delete key stroke has stopped working. The individual keys themselves seem to work fine. I have tried different keyboards (USB and PS2), different USB ports, rebooting without the keyboard attached and then readding it and rebooting again, removing the keyboard from the device manager and rediscovering it, checking the bios to make sure nothing looked amiss there, trying it in safe mode which didn't work either, flashing the bios (mb is an , if that matters), reinstalling windows from scratch, and threatening to hit the machine with a hammer. Nothing has made the keystroke work.
Since I reinstalled windows, it had to be some kind of issue with the bios, and it hasn't always done this. Since flashing the bios didn't seem to help, I'm at a loss. If anybody has any ideas where to go from here, I'd appreciate it.
