Computer name and local hostname not recognized at startup

Question

I've been having trouble syncing with .mac lately. (This isn't syncing question.) Looking at my console and system logs, it would appear that my computer and network connection have a problem right from the start (except that I can connect to the Internet and can send and receive mail no problem). But I think the logs below indicate that there's some disconnect because later on, when I try to sync or do something with iDisk, "Failed to register NSConnection" and SFIDiskMirrorCopyPair returned NULL" appear in the console log. Here's some of what the logs showed. I was wondering if anyone out there can make heads or tails out of it. Wondering if I'll have to blow it up and do an archive and install.
Any help will be much appreciated.
Thanks, Bill

Thank you for helping me. My computer is very old and it gets a lot of non-taxing use, like email and word processing. I'm trying to get another year out of it before I replace it. I first had to reset the PRAM because I had full-on freeze a couple of months ago. I couldn't get the computer to respond at all. Apple Support helped. They had me reset the PRAM, but the reason I've been resetting it now and again is that it seemed to fix a problem I was having with audio. When I am using Skype, Facetime or Gchat there was a crackling sound so loud, I'd have to hang up. Resetting the PRAM seemed to take care of this. I read around a little on the Internet. There was some suggestion that maybe my logic board is failing, at which point I would really have to replace my computer. But I was hoping for some pointers about this keyboard. I spent a couple of days reading and didn't find anyone having quite my problem. I guess it wouldn't really be such a problem if I didn't have this audio problem as well.
