I'm on a Windows 7 desktop with an external ps2 keyboard and its Caps lock key is behaving in opposite manner, like when I turn on the caps lock and the caps lock key light is lit its typing in small alphabets and vice-versa. It works fine for a while after rebooting the system however it re-appears again so I'm trying to resolve the cause.
I've gone through several forums and here are the several things I've tried :
- Press both shift keys down.
- Press tab and check if some shift key is down.
- Check for sticky keys.
I've also read that it could be some program modifying the way caps lock works but that's not the case either because I've checked the task manager and there is no such strange process running which could do so.
I've tried using On screen keyboard and its showed that the caps lock key is pressed whereas on my physical keyboard it wasn't and vice-versa. What could be the possible cause ? Thanks for any suggestions or help in advance.
