Having problems re-installing OS

hello world!

PowerBook + G4 +17 in Albania.

Have one big problem on to operation system,

At first he was in version 10.3 ....

But in many applications, "update your system to install".

(Example - skype, chrome, and other)

---> 1 Step = Download torrent 10.4 .... (CD 4) PowerBook system,

---> 2 Step = Initially I tried to start from (1 USB - but did not give any result in BOOT)

---> 3 Then, Burn 4 CD,

1 (boot-first) + Error or another version should begin.

2 (BOOT not start to enter this CD2)

3 (BOOT not start to enter this CD3)

4 (BOOT not start to enter this CD4)

---> 4 Step = After several days, the 4 CD outlines a DVD.iso

and finally went on smoothly, work from DVD.iso

---> 5 Step = Reboot and press "C" button, select Boot From DVD....

In the above process was to 89% ... loading, but the DVD was not in the paper.

after about an hour of ( Turn off - Power button )

The situation now is that there is no system left
