I have a I7 920, with 12GB DDR3-1600 Memory, 2 x 300GB Raptors in a RAID 0, 1 x 300GB standalone and 640GB Standalone, and a ATI 4870x2 video card. I am upgrading using a DVD, and basically it's taken 7 hours before I aborted the upgrade (62% completed migrating folders and files). All my other upgrades have gone reasonably quickly (Though not as quickly as some other installs and upgrades seem to go on lesser hardware) though the other 6 builds I have run. I don't really want to run a fresh install, can anyone suggest a solution? Does Windows 7 not really like ICHR10?
