you have the same problems with seg. fault also in rescue mode? I don't 
quite understand from your mail. None of your applications work or just 
a few? Have you tried several different commands?

Hacked *is* a possibility. Check for open ports on your machine. Best 
thing to do is to scan it with nessus or something like that from 
another machine because netstat can be altered by the hacker not to show 
open ports corresponding to some processes.
Btw, I don't think that just resolving the problem is the good thing to 
do. I always try to find out what caused the problem so I can make sure 
the thing never happens again.
And this can be done *only* using another machine. I would then check 
the integrity of the files and of the hard drive. I incline to think 
that given the fact that you cannot reinstall the os it is a hardware 
problem. You might find a lot of bad sectors in wich case I would throw 
the HDD away and buy another one. If everything checks out I would the 
check the RAM.
