I play ffxi, and it hard locks my system, and I hear the music looping. I have to power down my system, and power it on. Everything else works fine on my laptop. FF14 runs well. FFXI is the only game that locks up my system. Here are my specs
core i7 1.7 gig
6 gig ddr3 ram
5870 M

I have the newest drivers for all of my hardware, and I don't have any background apps running. Thank you.
