I'm currently using the 2011 line iMac (specs below)

Recently I've installed a Windows 7 Ultimate 64bit on my iMac via Boot Camp.
Everything runs fine after boot camp driver installation, except the Blue Screen Crash.
It happens almost all the time on Windows 7, and the error that I recall appeared on the Bsod is 'PAGE_FAULT_NON_PAGE_' something like that.

I was wondering if anyone have a solution for this matter.
