Rush keeps in crashing while working with it

Hello,

I hope some one can help me. 
I had a brand new desktop to work on Rush and I have 2 screens in front of me.

If I start Rush, I have the Adobe Express account, Rush starts normal. 

There are times that when I open a file, the music bar under de clips/photo's is crossed with a green stripe and the music bar itself is red. I can push play and the video's/photo's are passing but there is no music anymore.

When I want to load the previews in the Edit section, I sometimes get a green shot of a clip? Don't know what that is? 

Then when I upload a photo or a video, Rush starts to stutter. I can press play but but the needle stands put and het music and video/photo's are passing  or it is the other way around.

I cannot open Rush and just edit a video. Everytime Rush shuts of, my desktop is crashing, my screens are shut off. I can restart the whole desktop.

Does anyone knows what the hell is going on?
