Acer Aspire 4530 (w/Athlon X2) install problems

Greetings to the community, I'm davidpoiu, and I'm trying to install a patched Leopard in my computer.
My PC is an Acer Aspire 4530 (AMD Athlon 64 X2, 2 GHz, 3 GB RAM, 320 HDD...)
So, here's the deal:
First, I've downloaded iAtkos 7. It firstly started, but since I hadn't a clean partition for it, I couldn't install it (And I have important stuff in the partitions) So, after a few boots, it practically doesn't start right now. It always either reboots or freezes, no matters which option I type in darwin (-x, -s, -f, -v, -legacy, cpus=1, kernel change to mach_970 and ToH and so on)
So I got iDeneb, and it started... but it didn't recognized my HD, and it started to suffer the same problem as iAtkos (constant rebooting or freezing)
Now, I got Zephyroth' distro specially for AMDs. It starts... and then reboots. Now it shows less messages, and always reboots.
What can I do? I've tested a bunch of options right now.
Plus, why it becomes harder to boot? For me, that's kinda weird, because the CDs have no scratches or damages in their surface.
Any more information than you need, I'll give it.
Thanks for the help.
