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.

Does ctrl-shift-esc work in starting Task Manager?

 

Right click on the Taskbar. Select Task Manager. Does that work?

It does not bring up task manager, but right clicking and selecting does.

I am not sure but from the looks of it somehow the motherboard is not getting the key sequence from the keyboard. Does the Windows key work when used with other keys like E for Computer and L for Login Screen?

The windows key works fine, so do any of the other keystrokes I've tried, just not ctrl-alt-del. I'm baffled. I thought that if there was somehow a corruption in the bios that wasn't allowing it to recognize the keystroke, that flashing the bios would fix it, but that failed, so I'm at a loss.

This is a strange one. The only thing I can think of is some startup item may be causing the issue or perhaps some setting buried in BIOS but I never heard of that one.

 

You can check your startup items by running msconfig and look under the startup tab. Disable one at a time and then do a Ctrl Alt Del after boot. You can use ProcessLibrary to determine if one is essential if you are not sure what it is.
