If you dont run anything overclocked then maybe bad RAM.

 

Run memory diagnostic:

 

Press Win key + R and type in mdsched.exe and hit enter.

Allready did.... no errors etc. RAMs seem to be fine.
I also get Blackscreen when i trie to restart the system. But i get this Blackscreen only when i get up on a new day i turn on my pc, i use the pc for a while and when i trie to restart i get blackscreen. When i shut down the system (Blackscreen) and trie to start, the system starts fine but a blackscreen isnt normal i guess.

Maybe someone knows this but im wondering if the crashes could come from my Streaming PC, I use a 2 PC Stream Setup with the Elgato HD60Pro is it possible that if the streaming PC isnt updatet with drivers etc. could he be the reason that my Game PC Crashes? My Streaming PC never crashed in 6 years. My Gaming PC is hooked up with HDMI over the Elgato so if my Streaming PC isnt running i get no Picture from my Gaming PC but im fine with that i just wonder if a streaming pc can crashh the other gaming pc.
