Sudden loss of LH Ctrl key function.

Best guess is that the membrane switch for the LH Ctrl key has failed.

Test it by poping the key off (carefully) and pressing the contact down and seeing if it works. If the key itself isn't damaged or broken in some way sometimes "stuff" gets under the key. I've had users with everything from the sprinkles on donuts to coffee spilled in there.

Chas is probably correct and ReWrite's suggestion may help.

If you have one of the newer cheap keyboards, go ahead and replace it if cleaning debris doesn't help.

If an older expensive model with replacable key switches (e.g. IBM PS/2 or Keytronic Pro), you may be able to obtain replacement key switches from the manufacturer.

If it's one of the newer, flimsy OEM keyboards, consider this an excellent opportunity to purchase a quality keyboard. Especially important if you use your PC a lot.

I have always considered the monitor, keyboard, and mouse the most critical components of a system. They are your interface with the beast. It's amazing how many people will fork over major bucks for speed and latest gadgets and then get the standard crappy keyboard, mouse, and monitor.
