If a solder joint is bad, it will always bad either cold or hot.

This could only related to PSU. Can you try with a different PSU?
Did you uninstall Catalyt then reinstall after put 3 cards in? If you didn't do this, put 3 of them in with crossfire bridge properly seated. Restart PC, uninstall previous Catalyst then clean it with this:
ATIMAN Uninstaller v.6.1.3 Link
(Run with administrator privilege. Some antivirus software will give a false positive. Let it restarts to complete the uninstallation - Disable UAC to install tis cleaner).
Then install latest WHQL Catalyst 11.10 http://sites.amd.com/us/game/downloa...n_win7-64.aspx
You only have to do this 1 time because you are replacing your previous with 3 x6970s.
