Whenever I am online with either IE9 or Firefox(doesn't matter which version - 3.6.17, 4.01, 5.0b1), after few minutes, my computer would get frozen, keyboard and mouse cursors disappear, and the only thing I could do is power off, then power on the computer. It is very frustrated. I wonder if there's something to do with modifying the spp files(when activate and un-hide features). Is there any other way to activate 7850 and un-hide all features without modifying any system files? Please do not refer to any other Win8 builds. Thanks in advance.
