It happens when the intro music is interupted, then it is going to quiet and quit to desktop. Is enoby here who is able to give me some advice? I dont want to reinstal… really
Because you’ve installed new cpu & ram, the first thing you should check always is your cpu temps and test your ram.
Do a quick stress test on your system.

If ok, search stop loading on this forum.
thx for reply… Unfortunately I did integrity game files check on steam… Now I am downloading the whole game again.
BTW… The temperatures were absolutely OK. The problem was somewhere else. Meabe the reinstaling will solve this
Hi!
Did you re-install Windows? I don’t see it listed in your post. But if you put in a new motherboard, it is best to reinstall Windows. Putting back in the old drive from the old motherboard install, may cause issues.
If I were you, I would start from a clean Windows 10 install. (that is, if you did not do it). 
Before you do anything else. Before you reinstall another program. Unplug all peripherals and start the sim with only the mouse and keyboard plugged in. Yes, even USB headphones need to go. I spent over 2 days reinstalling Windows, Steam, and the sim twice.
Mine was actively crashing at the exact spot your is. It started the first time I ran with nothing. I turned it off, plugged everything in. No problems since. YMMV, though.
It’s not one of Zendesk’s suggestions.
Hi yes. I removed all usb’s… no help. Will see after the reinstal
It’s now my first troubleshooting step. Ten minutes to try, and it might save a day or two. Ya’ never know.
!! You need to make sure you system is running properly before anything else. There are some very good answers and suggestions posted here in reply to your question that need to be done before trying to install and run msfs or anything else for that matter. Honestly it’s pointless to help until we’re sure your system is up and running properly to start with.
Guys I have to say… thx a lot. I did fresh instal of systém, Fresh instal of MFS2020 and now… ale is running as smooth as posibble.
