Stuck shift keys - windows 7 64 bit

I've tried turning off all accessibility option. I've tried switching keyboards. I tried hitting shift 5 times, and every other key press combo purported to solve the problem. The only thing that temporarily helps is a reboot, but the problem resurfaces seemingly at random.

Using a Logitech G15 usb keyboard, also tried a microsoft wired ps/2 keyboard. I have installed several programs recently, mostly small apps dealing with overclocking. The cpu was briefly overclocked, then put back to default, I don't think it's the cause of the problem. 

Edit: Also, relogging temporarily fixes the problem as well.

_________  <--- Was able to do that because the keyboard behaved as though the shift key was always held down. 

Well, I sort of gave up. Rather than figure out what the problem was, I opted to go for a surefire solution. I used windows restore to roll back 36 hours. Problem solved.

I'm convinced it was a problem with overclocking software of some kind.

Anyway. thanks for all your help.

    I have the very same problem from time to time. It doesn't happen often, but when it does I am using Corel Draw.

    Basically Shift is turned on and I can't turn it off. A restart always fixes the problem.

    I have all the Sticky Keys options turned off too.

    It makes the system unusable as everything is shift clicked.

    Using Windows x64 too.

    If you tap left Shift and tap right Shift, this should flush any internal key state - does this clear up the problem for you?

    I have the same problem and I am using W7 64 Pro, so irritating !!!

    It began after some major update. I usually do the OS, drivers and software update at one go. So I cannot say exactly say what the root cause  is. I would need to restore the system a few month back and start installing the updates one by one, and then observe the system.

    The most annoying it starts by itself, one moment you scroll down, the next moment it zooms in or out.

    What I do is just press, shift, ctrl and alt in random and it usually goes away till next time the Shift stuck again.
