Error - Driver not Available (Error code 2-5)  

I have the exact same problem but I am using Vega 3 Graphics, also needing help.

Hi @billybeaw and @ruvikyu,
For further analysis, could you please run dxdiag.exe on your primary machine, click "Save All Information", then attach the output file (dxdiag.txt) on your next reply.
PS: Attach option should be visible on your side after your second post.

follow up: What is your Windows 10 build version?
You can see it by running "winver".

I have ran dxdiag and saved the .txt file, the problem is I can't seem to find the option for attaching .txt files, and my dxdiag report exeeds the character limit.

Hi @ruvikyu,  Attach option should be visible now on your side after your second post. Please check again..
