Couple of problems with suse sound and video

I have a dell e6500 intel core 2 duo with intel graphics. My sound clicks every now and then and it also beeps really loudly and obnoxiously. Also my video flickers with a scratchy image on loading x. One last thing it seems to be a bit laggy some times when i have a few applications open, i have a gig of ram and it is using around 300 or so. Any help is appreciated if not i am sure i will eventually figure it out, just thought i would see if some one else has ran into this.
