OK Portal 2 gave me the bug and now ...
Having said that there are a few games I have downloaded from Steam that have had problems starting on my system (WIn 7 64-bit) and I think I have found the problem.
FWIW I offer it hear ... I found that some games (especially older games) load to the taskbar and the screen flashes a lot (presumably trying to change to the correct resolution etc.) and finally gives up and just sits on the taskbar until I close it using the task manager.
This was really frustrating but I discovered that part of my Samsung monitor setup installed Multiscreen which was starting with windows. This tool allows the monitors to be divided into separate screen areas that you can send windows to etc. - useful but not essential.
Exiting Multiscreen solved the problem and now all my Steam games work fine.
