C# Visual Studio 2010 doesn't start debugging

Question

I'm developing with the Framework 3.5 in C#. When I click "start debugging" nothing happens. I've tried with other projects(including a new project) and they won't start. Instead VS2013 project doesn't have problems. Until 10 minutes ago it worked, i don't know how to solve. If you need more details ask. Thanks.

I tried:

• Restart Computer
• Reload Visual Studio
• Create a New Project
• Reset Configurations
• Repair Visual Studio

I noticed that with audio on when I start debugging it does the error sound without show any error message. It's like the debug is starting because the pause and stop buttons appear, but the program doesn't start. I tried to put breakpoint at the begin of the main(), nothing. While the "debugging" is started if i try to pause it appear an error message: "Unable to break execution"

I tried uninstall VS2010, it gives me "Internal Error: 1058". I used Visual Studio 2010 Uninstall Utility, it says Uninstall complete but VS2010 is still in the computer. I don't know what kind of evil is in my computer

I use xampp, so i stopped the IIS service to keep the port 80 free, i thought that this could be the problem. Then i tried to start IIS service and gives me this error: "Cannot start service w3svc on computer '.'" so i followed this IIS w3svc error and it worked, IIS now starts and i was able to uninstall VS2010. Well then I reinstalled VS2010 hoping the problem was solved. I was wrong, debug still doesn't start, same problem as above.

Solved. I formatted and reinstalled Windows.
