Hello, I've been browsing the forums for a while now and decided to finally register. Anyways, I have been using Windows 7 since the 7000 beta however, for some reason whenever i install the 64 bit version of the 7000, 7022, 7048 build i always get a BSOD right after the starting windows screen. The message i get is STOP : c000021a Fatal System Error. The weird thing is i only get this on the 64 bit version and not the 32. I thought it had something to do with my drivers but it also happens on a fresh install. Anyone have idea on how to fix this? I really want to use the 64 bit version since i have 4gb of ram.
