I have very big problem with my hack, i think it's problem with kernel or drivers

My hack works beautiful, but last week it crashed. I didn't do anything. I'm only powered off it. When I runed it my comp booted good, but when it started boot mac I see only "_"(without ", of course). Then I booted it with iBoot, but mic don't work and in sound sttings I see only one "stick" in mic sound level! It's very strange! My hack started lagging, almost every applicaition "freeze" when I run it. And my iPad don't connecting!!! I reinstalled mac, but problems hadn't gone.
Please help me!
If you need my IP for connect to my computer with ARD please send me PM.
