No Sound or Jazz Drice


I am having a problem with OS X. I only had sound for the first two days and then all of a sudden it dissapeared. Also, my jaz drive does not boot up in OS X. the only way that i can get sounds(sometimes) or the jaz drive to boot up and display is if i restart in classic, and then restart in OS X. And that only works some of the time, but it is a pain in the ass having to reboot in 9 and then in X.

any help please??????
