Hi, I am new to this Hackintosh thing, have never even touched a MAC but since my Kids keep wining they want a MAC I figured I'll try to give them a cheap one.

What I'm, working with is an HP pavilion a6618f, Motherboard ECS MCP61PM-HM Chipset: NVIDIA GeForce 6150SE nForce 430 Processor: AMD Phenom 8550 3 core, Integrated graphics using nVidia GeForce 6150SE, Audio Realtek ALC888S

HP Pavilion a6618f Desktop PC Product Specifications HP Pavilion a6618f Desktop PC - HP Customer Care (Canada - English)

I installed iDeneb v1.3 10.5.5. on a new 500gb HDD, there is no other OS on this drive.
I got as far as passed the Installation successfully screen. Click on reboot. I have to hold the powerbutton to reboot. Once it boots it displays the apple logo for about a minute and then goes to a screen which states. "You need to reboot your computer. Hold down the power button for several seconds....."
It ends up at this screen every time.
Could someone give me some pointers what to try next?
