Why did you get unmanaged hosting if you have no idea how to do anything on your server? I would strongly suggest spending some time googling the OS your server is running and practicing some simple commands on your server to get to 'know' it. You should at least know how to restart the various services (apache, mysql) and restart your server. And, of course, how to backup and reimport your database. The commands to do this are different depending on what OS you are running. Who installed the mysql/php/apache on your server? If it was your host, then they should at least tell you were the configuration files are for those applications and I don't understand why they can't tell you how to restart those services. However, once you find out the OS, you should be able to google to figure that out.
