Stuck at Apple logo after updating to 10.6.8

So I installed Mac OS X Snow Leopard through the installation CD along with iBoot and it worked just fine until I updated it to 10.6.8, which made it freeze at the Apple logo whenever I tried booting.

Can someone help me please?

If anyone with a Clarkdale/Arrandale processor runs into the same issue just go to the Extra folder, click on Extensions and delete AppleIntelHDGraphics.kext and AppleIntelHDGraphicsFB.kext
