HELP! iATKOS v7 Installation problem!

[cool7733]

Hi,
I have a very big problem with my installation of iATKOS v7.
After I finish installing it on my computer [with a succesfull installation!], on the first boot when it reaches the grey screen with the apple logo, it just hangs/crashes there! Also, the spinning circle never appears!
Also, while it is hanged, there is NO activity from my HDD!

My computer specs are:

HP Pavilion 760n
1.25 GB RAM
Pentium 4 1.8ghz CPU
Asus P4B266-LA Motherboard

Thank-you!! Please reply!
