Hi i just picked up windows 7 Home Pro 64 bit, Im having trouble getting it to run on 3 different motherboards. MSI K9AG Neo2 Digital. nope MSI K9N SLI Platinum nope Asrock K10n780sli x 3 wifi nope can any of your Gurus please let me know if any of these Motherboards will be able to run windows 7 Home Pro 64 bit . Im using a AMD althon 64 X2 5000+ BE cpu with 2 8800 GT 512 in sli with 3 gig Kingston hyper X 6400 memory. Im thinking this hardwear should be recent enough to run Windows 7 home pro 64 bit O\S Im asuming its my Motherboard's that are not windows7 ready. if its my Motherboard ill surrender and buy another asus M4n72-e I just swapped my 2 GTX 260 and my 940 Be cpu to this from my asrock M\B. after upgradeing my 8800 gt's and my 5000+ BE cpu and some Kingston Hyper X sli ready Mem. any help would be greatly appreciated. I hope i dont have to buy anpther new M\B. as i have the pretty new asrock 780 ! i am hoping for an Bios upgrade anyone know of any for any of these 3 M\B's?
