I just encountered this for the first time. CTRL+C & CTRL+V would not copy and paste. I could see one burning out or something, but both control keys are not working. Tried a reboot and it didn't help.

I have a ps2 mouse and keyboard, both plugged into a USB adapter. Just unplugged the USB adapter and replugged it in and the keys work normal again. Seems odd that resetting the USB connection resolved it and a restart would not have fixed it, but at least it was a simple fix. Hope that helps someone else.

You may have already assigned these as hotkeys for another program like Skype. You may be experiencing this when both programs are running.

It's still work but so slow and have to put 4-5 times.
Sometimes it's disappear when I restore my windows some previous days ago, but happen again after half an hour working.
I dont know why? might be virus or some function conflict together.

I got this problem in Word, in MS Office 2007 on newly installed Windows 7 (on a new Lenovo X200 laptop). The reason was a keyboard switch with a certain key sequence. See the tiny language icon at the bottom right corner of the screen? It got switched from standard English US keyboard to English multilingual (also had a French keyboard option). I went and removed all English keyboards except US. No more CTRL key problems.

Ctrlkey on my laptop HP6910 (WinXP) doesn't work from the left side, but it works from the right. In BIOS restored to factory default and it's resolved issue.

i think you have installed windows updates, bacause of these updatessome functions stops working. similar case was there with me. then I restore my system and everything was normal

I found very easy way to get rid of the side affects, it normally comes in when you have your laptop on for long periods of inactivity, just load back control panel and it should resolve the issue.

Hi Everybody,
I have given the laptop to the service centre and they have replaced the keyboard and everything is fine....for desktop it's rather much easy to check with new keyboard.

I was using old keyboard. Replacing with a new USB keyboard solved the problem on my AMD FX-4100 Desktop.

I bought a brand new dell a few weeks ago, and the control key randomly is hot so that when I press t in the internet browser for example it opens a new tab. It is really frustrating especially when it deletes things or exits from things.

Dell sent me a new keyboard, and I switched it and thought all of my problems would go away, but it still does the same thing. I am probably going to send the computer back to dell, but any ideas as to how to fix it?

My brand new dell studio is that way...but it's a different broken key every day. I have to slam down on the key to make it work, but the others work fine. then another day, it will be a DIFFERENT letter!
