Have you tried to clean the keyboard? Check in CONTROL PANEL country settings what is there?

touchpad driver

I've a suggestion. Turn off and unplug everything. With a thin screw driver pop the CTRL key off. Watch for a small rubbe ring that may jump. ( My toshiba A70 had this yours may not) It fits over the post under the key. See if the area is dirty or gooey,look under the key cap too. Clean and let dry.
See if you can pust the button to see if it's stuck down. Pull it up with a tweezer. Power up agin now to see if it's working. If so ...
Get this Lube ( Kmart auto), spray a small amount to ring an under key cap.

turn off and put back together.
Laptop keys don't wear out they usually gum out.

Did it appear to be functional? Popping back up after pressing it.

On a different computer so can give some more details.

The CTRL function seems to be self-enabled on an intermitant basis. So when typing all of a sudden I will open a new window, or start typing a in italics, open history or favs etc.

it happens on all accounts set up on the laptop.

I don't think that it has anything to do with sticky keys as this has been disabled.

Also the frequency of it occuring seems to change some days it is every other keboard stroke while others it is every 50.

Does any one have any ideas? Thanks in advance

Have you installed any new devices,hardware/software, updated drivers recently.
Remove them/it and see.
try a system restore to a point before the problem
Have yu performed virus scans
this one will check registry for conflicts as well as malware
click ONLY the box near mid page saying "Full Service Scan"

I had taken the hard drive out and reinstalled it. Problems seemed to start soon after, although I have no idea why the two should be conected.

the problem now seems to be resolved. I took the keyboard off the notebook and simply put it back in - that seems to have done the trick. No logic behind this I know but as it is working I will move on. If it starts to play up again I will let you know. Thanks for the suggestions.

Occasionally at school keys get stuck, like shift. And actually, the way to fix them is to just unplug the keyboard and smack that area of the keyboard pretty hard to unstick it. Surprised me just as much as it probably surprises you guys.

You can also try holding down ctrl+shift for 15 secs. This will release the modifier key lock. This happens when you hold down the ctrl key down for few seconds (happens a lot on laptop where the ctrl key is conveniently located right where you would rest your palms when typing.)

I know this is an older thread but this is the answer! On Toshiba laptops, satellite and tecra for sure, there is a lock function mode that can easily be set by accident if you're wrists or hands tend to rub across the touchpad/the fn key when you're typing. This is very inconvenient because, personally, I sometimes get mid sentence and then start throwing control keys. Sometimes turns out very badly.  

 

However, to disable the lock, you hit both the fn and ctrl keys OR ctrl and alt keys together and voila. There's nothing wrong with your computer, probably, its just this function toggle. Not sure yet how to disable it, but that's how to end it.
