Major help needed with my hackintosh?!

Hey guys,

I need some serious help. I'm new to all this apple stuff and I just yesterday installed ideneb Mac os X snow leopard 10.5.8 and it was all working good, but I don't have a internet connection, and I can't install imovie since it says "Imovie requires a graphics card that is compatible with Quartz Extreme. One or more graphics cards does not support Quartz Extreme" So what do i need to do to make all this all work. I am using my laptop Dell Inspiron 1440. It has a Intel Dual Core Processor T4400, 4GB of memory, 320 GB hard drive, Integrated Wireless 802.11b/g card, Intel x4500 Graphics card. It also comes with a webcam but that also doesn't work. But the sound does. Please guys I need your help. Anything would be greatly appiericated Thanks again. Also my keyboard isn't working at all when I press a key, and nothing types in =( and idk how to fix that either.

Don't have major help for you, just a little assistance which you may not need.
