Visual Studio 2010 keeps crashing on startup even after it has been removed and reinstalled fully

Hi,

I have been struggling for days on this issue now and nothing seems to work.

I have had visual studio on my pc (windows xp pro) for 18 months and it has worked fine, but recently visual studio (2010) has started crashing before it fully opens up.

I have tried uninstalling vs2010 fully then reinstalling but it is just doing the same thing.

The error message recorded in event viewer is a devenv runtime .net error.

Here is the full error message.....
