After turning the game unity is not responsible

When I want to test the game and I press my Unity stops responding. Unfortunately it gives me no error. I do not know what to do, everything I worked yesterday without a problem. You will say that it was my fault, but even as I want to launch a new clean design effect is the same.

I tried to uninstall Unity3D and install the new version from the official site but did not help.
No matter how much time will it take to turn on the game and so will not work (I waited over 1 hour).

Please help and sorry for my English.

 

You tried a blank project?

 

You probably have an infinite loop stalling the program.

 

@MD_Reptile So I tried to clear the project all the same.
@LaneFox It is not my fault codes do on pure project I have the same.

 

Which OS are you on? Have you checked your system logs?

 

When you say clear the project - you mean you created a completely blank new project? (Not just copied assets out of existing one)

I just want to clarify that, so we know it's not any setting or script from your project.

 

@StarManta I'm using Windows 7.
How do I perform Read user logs?

@MD_Reptile Yes, I created anew without any of my scripts or other objects.

 

editor log is at:
http://docs.unity3d.com/Manual/LogFiles.html

 

I'm not sure if it's for sure the logs.

 

Just to rule it out - you might try reinstalling/updating your drivers for the video card and sound card on your machine. Have you been able to play any games on that machine at all? I skimmed through your editor log but don't necessarily see anything wrong, but I didn't check thoroughly.

Are you using 64 bit windows 7? How much RAM does the machine have? Is it a fairly new machine (like less than 2-3 years old)? Have you had problems in any other software (not just games but maybe problems using office, mail clients, browsers...)?
