Apologies if this is the wrong section on which to start this thread. Still new to this forum and just joined out of desperation. I decided to give a try at Windows 7. Looked up Microsoft W7 site, and downloaded the 64-bit version. I'm VERY sure that I downloaded the x64, as the filename says: 7100.0.090421-1700_x64fre_client_en-us_retail_ultimate-grc1culxfrer_en_dvd.iso (I checked the 32-bit filename to make sure, which says x86, so very sure) Installed without a hitch, and upon first bootup, I proceeded to install my newly downloaded 64-bit drivers (nForce, nVIDIA Forceware etc..) and to my surprise it reported that I'm not running the 64-bit OS. I checked system properties, and it reports: I reapplied for another CD-Key to make sure that I was using 64, and reinstalled from scratch (3 times) Windows 7 still reporting 32-bit. I have looked all over the net looking for someone with the same issue, but I simply cannot find anyone complaning about it. CPU: Intel Core2Quad Q9550 M/B: Asus Striker Extreme II (so yeah, pretty sure my system IS 64-bit) Anyone has any ideas? This thing is driving me nuts as it's not making any sense, unless Microsoft screwed up the versions on download page.
