I don't know what to try but on install everything came up but at the install screen It showed a bunch of funny psychedelic colors. I could still make out labels and buttons but just barely and i could read text as well. Also i have a substantial amount of harddrive space left but it said i didn't have enough space to install. The only install i could make is the small and normal installs.
P.S. I would rather not do something as drastic as uninstalling SP 2 that would just cause a list of other issues.
