iDeneb v1.5 10.5.7 Leopard installation problem :|

Hy all.
When the OS is installing the system reboots :( after the loading bar passes almost 70%(aprox),it reboots...I tried at least 4 times.
And when i want to open my computer,and i boot into mac OS, it loads a bit ,then again it reboots.But thats probably because the OS was not installed correctly(because of the above problem) so please help me if u know whats wrong.I dont think that a chosed the right drivers and stuff from the customize menu (ideneb)
MY SPECS
Gigabyte motherboard 945GZM-S2
Intel Core 2 Duo e6600 2.4 ghz
