Ctrl keys stuck on all the time, how to turn off?

Ive used 3rd party software to disable my v and both ctrl keys and my PC is otherwise appearing usable if inconvenient. I'm thinking maybe hardware after all. But even so my pc starts acting like ctrl is pressed in that it wont let me open a new tab window normally. Its odd. Need to try a new mouse and keyboard again to be safe. after that ill try a mobo replacement

Tried a Microsoft brand keyboard tonight, worked perfect for 10min then the Ctrl key issue started. This time on the OSK the left Ctrl was highlighted. I unxlicked it but no luck.

So that rules out my keyboard
I'm using the front usb panel so it's not the motherboard

I have no idea how to troubleshoot this.

After a few more reboots and running cclesner and Malwarebytes my session ran normally on the alternative keyboard. Fingers crossed that tomorrow it works just as well.

Wonder of wonders, seems resolved so far.
