Startup and volume=broken

So, when using bootcamp today I was installing Republic commando for PC. While it loaded, it froze. So I turned it off and back on, but the windows parition wouldn't start up while loading. Neither did mac, unless I used the safe boot. It wouldn't detect my mouse, and I had to replug it. And finally, I discovered my sound didn't work. It shows that its at top volume, and its locked, with a transparent volume icon. So I can't listen to anything, use my windows parition, and I have to use safe boot (which takes about five minutes) to start up my mac parition. Is there any way to fix this?

 

Well, I can't access either if I start them normally.
And now when starting up iStopMotion 2 it says that my graphics card is insufficient to use the application, which I have used before and it had worked fine.
Yep, my mac is messed up.
