your onscreen keyboard or your physical keyboard has control key stuck. hope it is the former and you can fix it by open it and unstick it. otherwise you need to fix your keyboard.

you could have a stuck key(s) (higher possibility), software running that messes with the input, and having a virus (lower possibility) on the computer.
If it is wireless, then that changes all the possibilites. change the battery, or recharge it, test it on something else.
If a liquid has spilled inside the keyboard, It can take many days to dry it out, a liquid down in there can make a slight connection, or keep a key from moving properly.
If a key item is just stuck sometimes reletlessly pressing it over and over again can get it unstuck. When you can attribute the problem to a qualifyer key [CTRL] [Win] [ALT] [Shift] Sometime you can get that key unstuck by pushing it over and over again, until it begins to react.
Beating on a qualifyer key to try and get it operational, doesnt usually reek havoc on the rest of the system :-)
When testing keys it can be useful to open up a simple notepad , expand it to full screen, so keypresses (more often) land in something a bit more safe.
Just to be sure , it would not hurt to boot the computer into a "Safe mode" and test it there before assuming it was a hardware only issue.
If you cannot get into safe mode, it always helps to have Menu or shortcut access to Msconfig.exe. If the keyboard keeps you from getting into Msconfig, (using the mouse) in windows 7 , under administrative tools it is the item called System Configuration.
Assuming you can get into and use the system with the mouse, there are small utilities that can (sometimes) be used to see what the system thinks is pressed. Is it possible to show key presses and mouse input visually?.
