Just updated to win7 to try and wipe out a vista update loop that wouldn't die. Oneof4 spent many days working it, and I ran out of time. Now the catalyst center shows nothing but CPU data. No video cards. Dev mgr says something about corrupt files. I have uninstalled the drivers, but this does not seem to change anything. I have updated the drivers, but this too has no affect. I uninstalled and tried driver sweeper, with no change. Driver sweeper choked. Instructions for manually removing files from registry look very risky. Any ideas?
