Ctrl/Alt Button Issue

So I recently had to reinstall my operating system. And I'm not the smartest when it comes to computers but I do my best, push along, grab advice and help from those around me when I need it and generally try to learn as I go and figure things out for myself that will make me smarter in the long run.

So everything is up an running. I have downloaded all drivers and the likes for which I need to run smoothly. But it seems that I can no longer use my ctrl button as a hot key. I can no ctrl v or ctrl c or ctrl v anything that involves the modifier key of ctrl in conjunction with another key does not work.

While gaming i use a program called mumble that uses a push to talk button (push the button people hear you talk instead of having an open mic the whole time) and the button i use as my PTT is ctrl and that works fine. It just seems to be that when ever i use it in conjunction with another key it fails to do what I need it to do. Any help on this subject would be very helpful as I often use the modifier for many things to make life easier.

Seems to be the same issue with my ALT key as well
