Problems with installing iAtkos S3 V2 on a Compaq NX7400

Hello, I have an HP Compaq NX7400 with a Core Duo T2400, 1,5GB of DDR2 RAM and GMA950 graphics. It would seem that it should run Mac OS X 10.6 just fine, however after putting iAtkos S3 V2 installer on a USB,the installer stops at 18 minutes remaining, the log doesn't show any errors, I still can move the cursor around and the animated progress bar still animates. The hard drive LED blinks once in a while, the USB Stick LED doesn't blink at all. What could be the problem? Thanks in advance for help.
