Lion: Screen Frozen, can't click but can move mouse

Hi, not sure if this is the right section to post in.

I did an apple HDA rollback for audio using multibeast, and since my hack is taking very long to boot and once lion starts it's frozen. I can move the mouse around the screen but cant click anything, you can see programs loading in the background as well. It takes anywhere from 5-15mins for the computer to suddenly let me click again, then it runs very slowly and the spinning wheel continuously pops up as I try to enter certain programs. When I go to to the settings app it always crashes.

Does anyone have any advice on this problem?

Thanks for the help

Ok still having problems, looked at a lot of previous posts talking about the applehda rollback etc.

Have booted in verbose mode and attaching a screenshot. I dont understand much about what is going on here but it appears to me that applehda is definitely the probelm.

Any advice would really be appreciated!

Thanks
