Hi - coming from a Mac background I recently built a new PC and decided to put Deepin on it. However I have several problems.
Mainly when I peform certain actions the OS crashes back to the log in screen and I lose any work that I have currently done. So far this happens when I:

1. Open the Deepin Store App
2. Plug in a USB key into any USB port on the PC.

I am totally up to date with packages and updates etc. Running driver manager informs me I'm using 1 proprietry driver. Intel-microde. However disabling this does not fix the problem.

Also - I cannot get my 4k monitor to be recognised. I'm using a dedicated graphics card.

As this is a new motherboard would I need to update the BIOS? Can anyone shed any light on this problem?
