how to reinstall snow leopard without install disc
I recently took my computer in to an authorised repairer (MyMac Flinders St., Melbourne Australia) to get my LCD screen replaced under warranty, as it had developed a yellow line running down the right hand side of the screen. Whilst it was in the shop I decided to have a new 1TB hard drive put in, and get the OS updated to Snow Leopard (they loaded it up, I did not get install disc). Since then, I have had massive problems with my computer. The computer sometimes would not turn on, turn off, or simply freeze. I took the computer back in and was told it was a software issue, so they did a format reinstall, and told me the problem was fixed. Within hours of getting the computer home, the same problem occurred. I took it back, was told the same thing, and with the same end result (computer not working). I then took it into the Apple store in Chadstone Melbourne, and was told it was the hard drive that was at fault, and not the software at all. I then tried to get the hard drive replaced through MyMac Flinders St., as I now thought it might be the hard drive that was the problem, and with great reluctance and many minutes on the phone they finally agreed. I had big problems getting this agreed to, because my computer was now out of warranty. So, I guess this is a two part question:
1. I've got the computer back now, with the new hard drive, and it seemed to be working fine, but i've since discovered my phone was not syncing up correctly, and was told by Apple support to check my iSync.. to which I was greeted with the error message "iSync can't be launched iSync Manager not available" to which Apple support gave me a step by step instruction download to fix:
In the Finder, choose Utilities from the Go menu.
Open Terminal.
In the Terminal window that opens, type or paste the following command on a single line:
/System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync .pl full
Press Return.
When the operation is complete quit Terminal
The only problem being.. the Apple Terminal was missing. The program logo was there, but unable to launch. I figure my best bet will be to do a reinstall of Snow Leopard, but I am unsure of how to do this without the physical install disc. I have a backup on an external hard drive.
2. With my computer being now out of AppleCare warranty, I would like to know my options if this problem is unfixable, as my computer was fine before I took it into the authorised repairer, and also in warranty. I don't think I should wear the financial costs of replacing this computer.
Your help would be greatly appreciated.
