Ok thanks, but I think I maybe have find what cause the reboot of my PC !
Have to investigate, but I think it's the turn off screen option of windows ! Not Trinity !
I have test to launch the bot, and immediatly put of my screen manually, the bot work good since 1 hour !
Will try when back to home to put screen saver on 10 min, and to see if it reboot my PC when DB is working !
