so I just download two games heroes 3 and disciples 2 and non of them is starting up??

Through Galaxy? Without Galaxy?

Is there any "error" message?

through galaxy but even before without galaxy it just start to launch but in like 4 sec it makes negative sound and stop launchingand disciples 2 says error IT cant iniciate or something like that

add them to the list of DEP exceptions (presuming you're on windows), run as adminstrator. call back when you've tried that.

any other idea boss I tryed .....and yes I have windows 10

Found this searching for "cannot initialize" and GOG. It just happened to be a thread about Disciples II:

[i]I had the same problem on Windows 7 x32.
I found the solution trying to run different game screen resolutions.
Go to Disciples 2 game configuration and change the resolution to 1024x768 or 800x600.
The game can't initialize on 1280x1024... It's a pity.[/i]

Please, for the love of god, include some more information about your hardware, exact error messages and troubleshooting attempts.

Right now your question boils down to "my mode of transportation made a sound and then stopped working" and people here are left wondering if you're talking about a skateboard, bycicle, motorcycle, car or plane...

And by "Heroes 3" do you mean Heroes of Might and Magic 3? If so then:-

If after trying to launch them, the CPU usage is abnormally high on a windows 7 machine :
