Help restore a Backup

Hello,
I have made a Full Backup of my PC with a RAID5 System with Acronis 2013 .
I have restored it several times on the same PC when i had problems.
Today i have tried to restore it on the same PC but cannot restore it.
It starts restoring but when it arrives at 2 minutes to the end,
it seems to stop.
I can see always 2 minutes to the end but it seems to be stuck.
The CD Drive led went off and the bar does not move.
As i have made 4 diufferent Backups with the same Configurations,
in different days, i have also tried to restore them but getting the same results.
I have tried also to delete and remake the RAID5 but no luck.
I tought that there was a problem with the Hard Drives so i tried to install the Wndows 7
as new as the first installation and the installation get trough till the end without any problems.
Please how to solve?
Thanks
Enzo
