Compiler freezes

[Mays]

So I've been using Microsoft visual studio C++ 2010 for a couple of months. a couple of days ago I changes the name of project and cpp file in Sourses i've been working in, then thought about it and changed it back. Since then whenever I try to "Debug and Compile" whole program just freezes and doesn't respond. I have to force kill it. Also the project that I try to debug keeps hanging among active processes not just as one process but as three and I can't force stop it. Only restarting helps.

I tried reinstalling Visual C++ 2010, tried 2015 and I think 2013. It's the same story, even a simple "Hello world" freezes the compiler and the process is stuck in active processes 3 times...

Any suggestions on what the hell happened here? =)
