I put both values at 122 and Filter Keys (after coming back on when I restarted the computer to try and fix the shift key problem) is still on (assuming that this time it is indeed Filter Keys). I do have another keyboard, though when I plugged it in and used it, it reacted the same way as the original keyboard. I just don't understand this.
edit--- the other keyboard DOES work. Utilising the on-screen keyboard to see what's going on, The bad keyboard has both shift keys and both ctrl keys locked on.
The old keyboard does not. So this may indeed be a hardware issue.
double edit--- the other keyboard is now exhibiting issues as well. I was told to format my hard drive and reinstall Windows, so I will do that.
