Terminate action option not working

[teognost]

After last discussions -I reinstalled OS on this machine from the scratch.
It was relatively ok for long time -build remained frozen quite rarely at a step where C# solution was compiled in a Make VS.Net step -but 3 weeks ago started to be quite bad as i cannot have any build finished on this machine.
All the builds remain now frozen either at the "Make VS.Net" step (last line in log is "Pre-processing...") or at a "Zip Files" step (last line in log is "C:\SrcFolder\Release -> C:\TrgFolder\Release.zip")
I updated VisBuild to latest version 7.7a but no change ,builds are still freezing.
Any idea what to do next to fix this issue?
