Hey, keronflex! Just wanted to check and make sure this behavior isn’t caused by Razer. If you could try the steps on this post:
If it continues, could you provide a DxDiag file? Copy and paste the text file created and paste it between two ~~~ like so:
~~~
DxDiag Here

If you have issues pasting here, use Pastebin and post the end of the link. (ie. 123456 for pastebin.com/123456)
@shantimomo, this sounds a bit different from OP’s issue. If the system is fully shutting down when Diablo III is launched, there is going to be some major concerns with either driver corruption or with hardware issues. Diablo III alone cannot cause the system to shut down, but rather something on the system and Diablo III interacting with it caused a faulty driver or hardware to improperly work that resulted in the shutdown. Here’s our support article on unexpected shutdowns with a few suggestions that can help troubleshoot this. You’ll want to have a local technician take a look at the system for any errors to pinpoint the issue.
