Just got win7,was running XP 32 bit home edtion,,I put the window 7 64 bit disk in and a message said not compatable with my system.I have installed Windows 7 32 bit and it runs fine.Is there anyway I could go to 64 bit?.Could format my hard drive then load Win 7 64?.The windows advisor says my system can run 64 bit.My system is,Q6600 (overclocked to 3.2),Asus P5Q motherboard,ATI 4850 512,4Gb ram.Thanks guys
