installing 2012.10

[Peter Vágner]

Hello,
Today My PC got hard power off due to power outage.
Unfortunatelly it is now broken and displays low resolution mode at the 
beginning.
I have not enough expertise to fix it my-self fsck did not help.
I am therefore speculating. Is there a more recent distro preferrably 
running gnome 3.6 which I can install without sighted help and get fully 
operational my self?
I think I can backup my files using live cd before installing.
I would be happy to do it tonight. Can you please give me some advices?

Greetings

Peter
