iatkos Snow Leopard Problem

I am running Aitkos v7 updated to 10.5.8 dual boot with windows 7 .with everything working except wireless.I even have Quartz Extreme enabled and the right resolutions now on my Acer Aspire 5570-2609. But heres my problem.I have tried many times to install Aitkos Snow Leopard and every single time with all different customize settings i get a message after install saying hold power to restart over and over again.I googled this problem many times and got nothing heres the funny thing though, I can hit -x and boot to desktop of snow leopard no problem? Anyone have any ideas on this because i really need to run the 4.02 sdk and i need Snow Leapord to do it .I will gladly share any information i have on Leopard 10.5.8 on an Acer and how i got Quartz working ect. Please guys im hoping someone out there has the answers i quest for .Take care and thank you for all the silent information i got from this website in the past.I wouldnt even have Leopard if it wasnt for help i recieved here.
