Hey everyone, i thought i had everything working fine until i tried to run chess lol. QE/QI is on and works cuz i see the transparent bar at the top and the general OS works very snappy and videos play fine but anything that involves graphics rendering like games, itunes etc causes the system to freeze completely. I find it ironic cuz i can watch HD videos in youtube or quicktime just fine. So what is the problem here? Any ideas?

Setup:
iPC 10.5.6

Pentium D 3.0 GHz
3.0 GB RAM
ATI X1300PRO (installed with Natit + edited ATI RadeonX1000 kext) QE/QI Supported.
BCM5754 ethernet

Any suggestions would be great!
