Sometimes I can't even press the first button

[SneakadyBug 2]

So occasionally when I get on DayZ, it won't work AT ALL. The "I Understand" button will flash like it is clickable at first, but then it will just stop and freeze for a few minutes. If I decide to wait it out, The next screen that comes up does the same thing.  It will keep doing this until I try to join a server, and then it will never load. Whenever the screen becomes responsive after the few minutes of waiting, it will stay responsive and act like nothing is wrong until I click something. Does anyone know what is wrong? I thought I fixed this yesterday, because I figured my PSU wasn't putting out enough power, so I unplugged a spare hard drive, and everything started working flawlessly, but when I got home from school it stopped working. Any advice?

I have a similar problem, it is all the same but I can't even click the "I understand" button. This is also happening on my Arma 2 and OA.
I really just want to play some DayZ. And this isn't a spec problem, I have been able to run it before. So please, help!
