Does anyone have any idea why an upgrade of graphic card would produce a "No gears".

Reinstall the 777-200 Base Pack (csx772_1200.exe) and select Repair, then reinstall the 1.3 patch. See if that gives you your landing gear back.

Note. When I upgraded my graphics card from the GTX470 to the GTX770, I didn't encounter any problems with the landing gear not showing up.
