I recently upgraded one of my computers to an AMD quad core, 3.0 ghz, 600 watt power supply, 16 gig of ram, an MSI 760GM. 64 bit mobo. and 500 gig HD. I downloaded the 64 bit rc version of Mint 11, and it would start to install and about 3/4 done would freeze. I then tried Mint 10 64 bit, and it barely got started before freezing. 32 bit installed without a hitch. First time I've tried 64 bit software, but I wasn't expecting this. Am I missing something?
