Blackberry Z30 Touch not working

Hi guys, I got myself a blackberry z30 about a month ago, and it's been perfect until now. I go to unlock it, I swipe up just fine, exactly as it should, and then when I go to type in my pin I just get white boxes around the keys. Thats it. I can't even make an emergency call. Just sort of freaking out because I can not get into my phone. When it first starts up I can get in (literally as soon as the phone is ready to go) but it quickly goes to where only the swipe functionality is working (like the up and over swipe). Help?

What and what have you tried to do to resolve it?

Try resetting it if you haven't.
If that doesn't work, try an OS reload.
